how to choose a backpack

How to Choose a Backpack

Choosing a backpack becomes much easier when you stop asking:

Which backpack has the most features?

and start with:

What do I actually need to carry, and where will I carry it?

A backpack for commuting with a laptop should not be designed like a school backpack. A foldable travel daypack does not need the same support system as a hiking backpack carrying equipment for several days.

For most people, the right order is:

use → capacity → fit → organization → material → weather protection → details

Get the first three right and the rest becomes much easier.


1. Start with What the Backpack Is For

This is the most important decision.

Different uses create different priorities.

Backpack Use Main Things to Look For
Daily / city Moderate size, comfort, simple organization
Office / commuting Laptop protection, document storage, comfortable straps
School Capacity, durability, bottle pockets, organization
Travel Opening style, capacity, luggage compatibility, security
Hiking Fit, carrying system, ventilation, load transfer
Sports Ventilation, easy-clean materials, separate storage
Foldable daypack Low weight, packability, simple structure
Promotional Cost, branding area, practical everyday use

A backpack is easier to choose once you know which of these roles matters most.

Trying to make one bag perfect for every situation usually leads to a bag that is:

  • Too large for daily use

  • Too lightly built for travel

  • Too complicated for promotions

  • Too heavy to pack as a spare daypack


2. Choose the Capacity from What You Actually Carry

Backpack capacity is commonly expressed in liters.

But liter capacity is only useful when you connect it to real items.

Under 15L

Suitable for very light daily use, such as:

  • Phone

  • Wallet

  • Small bottle

  • A few personal items

  • Compact tablet

This size is common for:

It is usually too small for a full work or school load.

How to Choose a Backpack


Around 15–25L

This is one of the most useful ranges for everyday backpacks.

It can suit:

  • Office commuting

  • School

  • University

  • Day trips

  • Light travel

Depending on the shape, it may hold:

  • Laptop

  • Charger

  • Notebook

  • Water bottle

  • Light jacket

  • Personal items

For many everyday users, this is enough without becoming bulky.

How to Choose a Backpack


Around 25–35L

Better when more clothing or equipment needs to be carried.

Typical uses include:

  • Larger school loads

  • Gym + work

  • Weekend travel

  • Day hiking

  • Travel daypacks

This size gives more flexibility but can begin to feel unnecessarily large if the user normally carries only a laptop and a few accessories.

How to Choose a Backpack


35L and Above

At this point the backpack is moving more toward:

  • Travel

  • Hiking

  • Outdoor

  • Multi-day use

For backpacking specifically, trip duration becomes a major factor. REI currently uses roughly 30–50L for many 1–3 night trips, 50–80L for 3–5 nights, and 70L+ for longer trips, although the actual requirement changes with equipment, season and packing style.

Those numbers should not be applied to normal office or school backpacks.

A 50L commuter backpack would be excessive for most people.


Bigger Is Not Always Better

An oversized backpack creates its own problems.

It can:

  • Encourage unnecessary packing

  • Move more when partly empty

  • Add material and weight

  • Take up more storage space

  • Feel awkward on public transport

The best backpack is normally the smallest one that comfortably fits the normal load with a little spare room.

Do not choose capacity based on the rare occasion when you might carry twice as much.

Choose for what happens most days.


3. Check the Largest Item First

Before comparing pockets, measure the biggest rigid item the backpack must carry.

For an office backpack, this may be:

  • Laptop

For school:

  • A4 folder

  • Textbook

For travel:

  • Packing cube

  • Shoes

  • Camera equipment

For sports:

  • Shoes

  • Ball

  • Helmet

If the largest rigid item does not fit, total liter capacity does not matter.

A 20L backpack can sometimes fit a 15.6-inch laptop while another 22L design cannot because the internal proportions are different.


Choosing a Backpack for a Laptop

Do not choose a laptop compartment from screen size alone.

Two 15.6-inch laptops can have different:

  • Width

  • Depth

  • Thickness

A good laptop compartment should:

  • Fit the device without excessive movement

  • Have padding on the front and back

  • Protect the bottom edge

  • Keep zippers or hardware away from the laptop surface

A suspended or raised laptop compartment can also help prevent the device from directly hitting the floor when the backpack is put down.

If the backpack is primarily for work, this feature is more useful than adding several small decorative pockets.

How to Choose a Backpack


4. Fit Matters More as the Load Gets Heavier

For a light everyday backpack, fit is relatively straightforward.

The bag should:

  • Sit close to the back

  • Not pull heavily backward

  • Avoid pressure points

  • Keep the shoulder straps in a comfortable position

For heavier outdoor backpacks, fit becomes much more technical.

Shoulder Straps

Good shoulder straps should follow the body rather than cutting sharply into the shoulders.

Look for:

  • Enough width

  • Appropriate foam

  • Smooth edges

  • Adjustable webbing

Very thick straps are not automatically more comfortable.

Foam density, shape and load distribution matter too.


Sternum Strap

A sternum strap connects the two shoulder straps across the chest.

It helps:

  • Stabilize the backpack

  • Keep shoulder straps in position

  • Reduce side-to-side movement

It can be useful for:

  • Cycling

  • Hiking

  • Travel

  • Larger commuter backpacks

For a small lightweight city backpack, it may be unnecessary.

How to Choose a Backpack


Hip Belt

A proper hip belt becomes valuable when significant weight is being carried for longer periods.

Its purpose is not simply to stop the bag moving.

A correctly designed hiking hip belt helps transfer part of the load away from the shoulders and onto the hips. REI similarly identifies the hipbelt as part of the load-transfer system on daypacks and hiking packs.

For:

  • Technical hiking

  • Large travel packs

  • Heavy outdoor loads

this matters.

For:

  • School bags

  • Small laptop backpacks

  • Promotional packs

a large padded hip belt is usually unnecessary.


Torso Length Matters for Hiking Backpacks

For a technical hiking backpack, choosing only by body height is not enough.

Torso length is the more useful measurement because it determines how the shoulder harness and hip belt line up with the body.

Professional outdoor fitting guides therefore use torso length and hip measurement rather than simply saying:

Small backpack for short people, large backpack for tall people.

For an ordinary 20L office backpack, you normally do not need to measure torso length.

This becomes important as backpack size, load and carrying time increase.


5. Look at the Back Panel

The back panel affects both comfort and structure.

Common constructions include:

Simple Padded Back

Works well for:

  • School

  • Office

  • Everyday use

It provides cushioning without adding too much complexity.

Padded Mesh Back

Adds airflow channels or mesh-covered foam.

Common for:

  • Commuting

  • Travel

  • Outdoor backpacks

It can improve comfort, although no conventional back panel will completely prevent sweating in hot weather.

Suspended Mesh Back

Used mainly on technical hiking packs.

The backpack body is held slightly away from the user's back to improve airflow.

This is useful outdoors but adds:

  • Structure

  • Weight

  • Cost

and is unnecessary for many everyday bags.


6. Choose the Right Opening Style

The way a backpack opens changes how easy it is to use.

Standard Top / U-Shaped Zipper

The most common design.

Good for:

  • School

  • Office

  • Daily use

It is simple and familiar.


Clamshell Opening

The backpack opens much further, sometimes almost like a suitcase.

Useful for:

  • Travel

  • Clothing

  • Packing cubes

  • Business trips

It makes the full compartment easier to access.


Roll-Top

The top rolls down and closes with buckles.

Advantages can include:

  • Adjustable capacity

  • Fewer exposed top zipper areas

  • Outdoor styling

Common for:

  • Cycling

  • Outdoor

  • Commuting

The disadvantage is that reaching items at the bottom may be slower.


Drawstring / Flap

Common in:

  • Lifestyle backpacks

  • Hiking packs

  • Fashion bags

It gives a flexible opening but normally needs a flap or another closure if better security is required.


7. Do Not Choose a Backpack by Pocket Count

More pockets do not automatically make a backpack better.

Too many compartments can:

  • Add weight

  • Reduce flexible space

  • Make items harder to find

  • Increase zippers and sewing

  • Raise manufacturing cost

A useful everyday backpack often needs only:

  • Main compartment

  • Laptop section

  • One front pocket

  • One or two internal pockets

  • Bottle pocket

Then add more organization only when there is a reason.


When Extra Compartments Are Useful

Dedicated compartments make sense for things that need separation.

Examples include:

Shoe Compartment

Useful for:

  • Sports

  • Gym

  • Travel

Wet Compartment

Useful for:

  • Swimming

  • Fitness

  • Outdoor use

but only when the materials and construction actually manage moisture appropriately.

Camera Compartment

Requires padding and dividers, not simply another zipper pocket.

Laptop Compartment

Keeps electronics separate from general contents.

Bottle Pocket

Useful for everyday, travel and school bags.

The rule is simple:

A compartment should solve a real storage problem.


8. Choose the Material Based on the Environment

Backpack material affects:

  • Weight

  • Abrasion

  • Appearance

  • Weather resistance

  • Printing

  • Cost

Two of the most common materials are nylon and polyester.

INITIGIFT's existing nylon-vs-polyester analysis reaches the same practical conclusion: the fiber name alone does not determine backpack quality; denier, weave, coating and construction matter just as much.


Polyester Backpacks

Polyester is common for:

  • School

  • Office

  • Promotional

  • Travel

  • Everyday backpacks

Advantages include:

  • Good everyday durability

  • Wide color availability

  • Good printing options

  • Good cost control

  • Relatively low moisture absorption

Common constructions include:

  • 300D polyester

  • 420D polyester

  • 600D polyester

  • 900D polyester

  • Polyester Oxford

  • Polyester ripstop

A properly made 600D polyester backpack is adequate for many everyday applications.

How to Choose a Backpack


Nylon Backpacks

Nylon is common when:

  • Abrasion resistance

  • Tear resistance

  • Lower weight

  • Technical performance

are important.

Typical uses include:

  • Hiking

  • Travel

  • Outdoor

  • Technical backpacks

High-tenacity nylon can deliver strong performance at relatively low fabric weights.

But simply seeing the word “nylon” does not guarantee a premium backpack.

How to Choose a Backpack


RPET Backpacks

RPET is recycled polyester.

It can be used in:

  • Oxford fabric

  • Ripstop

  • Lining

  • Mesh

and can perform similarly to conventional polyester depending on the fabric specification.

If recycled content matters, check:

  • Recycled percentage

  • Fabric specification

  • Supporting certification or documentation

rather than relying only on an RPET label.


Canvas Backpacks

Canvas creates a different style.

It is suitable for:

  • Lifestyle

  • Casual

  • Fashion

  • Heritage-inspired designs

It usually feels more textile-oriented and less technical than nylon or polyester.

However, cotton canvas:

  • Absorbs more water

  • Is generally heavier

  • Needs suitable construction for demanding loads

It can be an excellent daily material without being the best choice for wet outdoor conditions.

How to Choose a Backpack


PU and Coated Materials

PU or synthetic leather is used where appearance matters more than technical outdoor performance.

Common applications include:

  • Fashion backpacks

  • Office bags

  • Corporate gifts

It provides a smoother, more polished appearance but requires attention to:

  • Surface durability

  • Flexing

  • Abrasion

  • Coating quality


9. Understand What “Water-Resistant” Really Means

A backpack is not waterproof simply because the fabric resists water.

Water can enter through:

  • Zippers

  • Seams

  • Needle holes

  • Openings

  • Mesh pockets

A PU-coated polyester fabric may resist light rain while the finished backpack still leaks through the zipper.

For ordinary commuting, a water-resistant fabric and protected zipper may be enough.

For serious outdoor rain exposure, look for more specific construction such as:

  • Better coating or lamination

  • Covered zippers

  • Roll-top closure

  • Seam sealing

  • Rain cover

Do not pay for “waterproof” marketing unless the complete backpack actually supports that performance claim.


10. Look at the Bottom

The bottom is one of the highest-wear areas of a backpack.

It repeatedly contacts:

  • Floors

  • Pavement

  • Tables

  • Vehicle surfaces

For school, travel and outdoor backpacks, useful options include:

  • Heavier bottom fabric

  • Double layer

  • Reinforced stitching

  • Coated bottom panel

A very good main fabric does little if the bottom wears through first.


11. Check Shoulder Strap Attachment

The strap material itself is only part of the system.

The attachment point carries significant load.

Look for appropriate reinforcement such as:

  • Bartacks

  • Box stitching

  • Reinforced seams

  • Internal backing

A backpack frequently fails at:

  • Strap attachment

  • Zipper

  • Bottom

  • Seam

before the main fabric tears.

This is why buying a backpack only because it uses “1000D fabric” is not enough.


12. Check the Zippers

Zippers are among the most frequently used parts of a backpack.

A good zipper should:

  • Move smoothly

  • Follow curves without excessive resistance

  • Stay aligned

  • Avoid catching lining fabric

Large backpacks and overloaded pockets place greater stress on zipper chains.

For everyday use, reliable construction is generally more important than decorative zipper features.


13. Consider the Backpack's Empty Weight

A durable backpack does not need to be unnecessarily heavy.

Remember:

Backpack weight + contents = total carrying weight.

Heavy:

  • Fabric

  • Hardware

  • Padding

  • Reinforcement

  • Extra pockets

can make a bag feel substantial in a shop but uncomfortable after several hours.

For:

  • Travel

  • Foldable designs

  • Daily commuting

lower empty weight is especially useful.

INITIGIFT's current foldable travel backpacks illustrate this trade-off: they use lightweight fabric, limited structure and breathable straps specifically because packability and low storage volume are central to the product.


14. How to Choose a Backpack for Different Uses

Daily Backpack

Look for:

  • Around 15–25L for many users

  • Comfortable straps

  • Simple organization

  • Bottle pocket if needed

  • Lightweight construction

Do not overcomplicate it.


Office or Laptop Backpack

Prioritize:

  • Correct laptop compartment

  • Bottom padding

  • Documents

  • Charger storage

  • Comfortable back panel

  • Clean appearance

A dozen small pockets are less important than protecting the computer properly.


School Backpack

Look for:

  • Enough capacity for books

  • Strong bottom

  • Comfortable straps

  • Bottle pockets

  • Simple organization

  • Durable fabric

Because books can become heavy, strap reinforcement matters.

How to Choose a Backpack


Travel Backpack

Look for:

  • Suitable capacity

  • Wide opening

  • Internal organization

  • Comfortable carrying

  • Luggage compatibility

  • Security for valuables

A clamshell opening is particularly useful when clothing is the main cargo.


Hiking Backpack

Prioritize:

  • Torso fit

  • Hip belt

  • Load transfer

  • Capacity

  • Ventilation

  • Stability

  • Outdoor material performance

This is where professional fitting matters most.


Foldable Backpack

Prioritize:

  • Low weight

  • Compact folded size

  • Adequate shoulder straps

  • Simple storage

  • Fabric strength relative to weight

Do not expect a foldable 15–20L daypack to carry like a structured hiking backpack.

They solve different problems.

15. A Simple Backpack Selection Checklist

Before buying or developing a backpack, answer these questions:

  1. What will it be used for?

  2. What are the largest items going inside?

  3. How much capacity is actually needed?

  4. How heavy will the normal load be?

  5. How long will the backpack be worn?

  6. Is laptop protection required?

  7. Does it need separate compartments?

  8. Will it regularly encounter rain?

  9. Does low weight matter?

  10. What usually fails first in this type of use?

If those ten answers are clear, material and feature selection becomes much easier.


Common Backpack Buying Mistakes

Choosing the Biggest Backpack Available

Extra unused space adds bulk and encourages overpacking.

Choosing Only by Liter Capacity

A backpack's proportions and internal structure matter too.

Assuming 15.6-Inch Means Every Laptop Fits

Actual laptop dimensions vary.

Thinking Thick Shoulder Straps Are Automatically Comfortable

Foam quality, shape and fit matter more than visual thickness alone.

Paying for Features You Will Never Use

Extra pockets, straps and buckles can add weight without adding practical value.

Choosing Material by Denier Alone

600D is not a universal durability score.

Fiber, weave, GSM, coating and construction all matter.

Assuming Water-Resistant Fabric Makes a Waterproof Backpack

The seams, zippers and opening still matter.

Ignoring the Bottom and Strap Attachments

These are common high-stress areas.


What Should Buyers Specify for a Custom Backpack?

For a custom project, start with how the finished backpack needs to work.

A useful specification includes:

Item What to Define
Use School / office / travel / outdoor / promotion
Dimensions Width × height × depth
Target Capacity Approximate liters if relevant
Expected Load Typical contents and weight
Main Fabric Polyester / nylon / RPET / canvas / PU
Fabric Specification Denier, GSM, weave, coating if required
Laptop Compartment Device dimensions and padding
Main Opening Standard / clamshell / roll-top
Pockets Front / side / internal
Back Panel Basic / padded mesh / other
Shoulder Straps Width and padding
Sternum Strap Required / not required
Hip Belt Required / not required
Zippers Type and specification
Branding Print / embroidery / patch
Quantity Estimated order quantity
Packaging Bulk / individual / retail

For a custom backpack, the most useful starting information is usually not:

“I need a 600D backpack.”

It is:

“I need a backpack for university students carrying a 15.6-inch laptop, books, charger and bottle.”

The second description makes it possible to build the specification around the real use.


FAQ

What size backpack should I choose for everyday use?

For many commuters and students, around 15–25L is a practical starting range. Choose from the items you actually carry rather than capacity alone.

Is a 30L backpack too big for daily use?

Not necessarily, but it is larger than many people need for basic commuting. A 30L pack makes more sense when you regularly carry gym clothes, extra clothing, equipment or larger school loads.

How should a backpack fit?

For normal daily use, it should sit close to the back without uncomfortable pressure or excessive movement. For heavier hiking packs, torso length, hipbelt position and load transfer become much more important.

Which backpack material is best?

There is no universal best material. Polyester works well for many everyday and school backpacks, nylon suits more demanding technical applications, canvas suits lifestyle designs, and RPET polyester is useful when documented recycled content is required.

Is nylon better than polyester for backpacks?

Nylon generally has an advantage in abrasion resistance and strength-to-weight at comparable specifications. Polyester often provides better cost efficiency, UV stability and everyday performance. The complete fabric specification matters more than the fiber name alone.

What should I look for in a laptop backpack?

Prioritize a correctly sized padded laptop compartment, bottom protection, comfortable shoulder straps and enough space for the charger and normal daily items.


Conclusion

The easiest way to choose a backpack is not to compare dozens of features at once.

Start with three questions:

What will I carry?
How much space does it need?
How long will I carry it?

Then choose the backpack around those answers.

For daily use, keep the design light and simple.

For laptops, prioritize fit and padding.

For school, focus on capacity, straps and high-wear areas.

For travel, consider access and organization.

For hiking, fit and load transfer become much more important than appearance.

After that, compare materials, pockets and smaller details.

A good backpack is not the one with the highest denier, the most compartments or the thickest straps.

It is the one whose size, fit, structure and materials match the load it actually needs to carry.
