Best Hiking Backpack for Kids: What Parents Should Check First

The best hiking backpack for kids is not necessarily the smallest, the brightest or the one with the longest feature list.

It is the backpack that fits the child closely, remains comfortable when loaded and gives them access to a few personal essentials without making the hike harder.

That distinction matters because a kids’ hiking backpack is not a child carrier. It is a small daypack designed for a child who is already walking and carrying some of their own equipment.

Before comparing brands or capacities, start with the child wearing it.

Fit Matters More Than the Number of Liters

A backpack can have the right capacity and still be the wrong size.

When properly adjusted, the pack should sit close to the child’s back rather than hanging away from the body. The shoulder straps should rest evenly without rubbing the neck, and the bottom of the bag should not hang far below the waist.

The American Academy of Pediatrics recommends choosing a backpack that is proportional to the child’s height, with two broad adjustable shoulder straps and a chest or waist strap to help keep the load close to the body. It also recommends using both shoulder straps rather than carrying the pack over one shoulder. See the AAP backpack safety guidance.

For hiking, the same basic fit principles become even more important because the child is moving over uneven ground rather than walking through a hallway.

Check the fit while the backpack contains the items it will actually carry. An empty bag can look perfect and feel completely different once water and clothing are added.

Do Not Choose Capacity by Age Alone

Searches for a hiking backpack for kids often begin with age:

What size backpack does a six-year-old need?

Is 10L enough?

Is 14L too large?

When should a child move to a bigger backpack?

Age can be a starting point, but it does not determine fit. Children of the same age can have very different heights, torso lengths and comfort levels.

Capacity should follow the activity.

For a short family day hike, a child may only need room for:

A small water bottle

A snack

A lightweight jacket

A sun hat

A whistle

A small personal item

A compact 10–14L kids hiking daypack may provide enough space for that type of load, provided the backpack fits the child and the contents remain light.

A larger pack may offer more room, but more room often becomes more equipment. The child does not need to carry something simply because it fits.

Start With the Empty Weight

Children have less carrying capacity than adults, so the weight of the backpack itself matters.

Heavy fabric, oversized buckles and complicated frames can use up part of the comfortable load before anything has been packed.

A lightweight kids hiking backpack does not have to feel fragile. Look for a balance:

Fabric strong enough for regular outdoor use

Reinforced stress points

Reliable zippers and buckles

Enough structure to stop the contents shifting

No unnecessary frame or heavy hardware

Lift the backpack before adding anything. Then add water and the intended equipment and let the child walk around the house.

If the bag already feels substantial before packing, it is unlikely to become more comfortable on the trail.

Look for Two Adjustable Shoulder Straps and a Chest Strap

Two adjustable shoulder straps distribute the load more evenly than a single shoulder or sling design.

The straps should be wide enough not to dig into the shoulders, but they should not be so wide that they rub against the child’s neck or restrict arm movement.

A chest strap is particularly useful on a children’s hiking backpack. It helps stop the shoulder straps from sliding outward while the child walks, climbs or bends down.

The chest strap should sit across the upper chest—not at the neck—and should be simple enough for an adult to adjust quickly.

A waist strap can add stability, but it only helps when it sits in the correct position and matches the child’s body. A poorly positioned decorative strap should not be treated as a real load-bearing hip belt.

Decide What the Child Carries—and What the Adult Carries

A child’s backpack should not be treated as a smaller version of the parent’s pack.

Prepared adults remain responsible for the group’s safety equipment, navigation, first-aid supplies, emergency shelter and backup clothing. The National Park Service recommends that prepared adults carry the Ten Essentials when hiking with children, including water, food, sun protection and appropriate clothing. Read the NPS guidance for hiking with kids.

A child can carry a limited set of personal items, depending on their comfort and the hike:

Personal water

One snack

A light layer

Sun hat

Whistle

Small trail notebook

Lightweight gloves or spare socks

Keep the heaviest items close to the back and balance the left and right sides.

Do not depend on the child’s backpack for an item the whole group may urgently need. If the child becomes tired and removes the bag, the adult should be able to take over without losing access to essential group equipment.

Make Water and Snacks Easy to Reach

A kids hiking backpack should not require a complete stop every time the child wants water.

Side bottle pockets are useful only when they securely fit the bottle being used. A shallow pocket may look convenient in a product photo but allow the bottle to fall out when the child bends down.

If the child cannot comfortably reach the bottle, an adult may still need to help—but the bottle should remain visible and easy to remove.

Snacks should also have a predictable location. A simple front pocket can work better than several small hidden compartments.

Good organization is not about having the most pockets. It is about the child learning where each item belongs.

Compartments Should Simplify the Bag

Multiple compartments can help distribute equipment and prevent everything from settling at the bottom.

But too many pockets create another problem: the child cannot remember where anything is.

For an ordinary family hike, a simple structure is enough:

Main compartment for clothing

Side pocket for water

Front or top pocket for snacks and small items

Interior label or contact-information area

Sharp, hard or heavy objects should not press directly against the child’s back.

If the backpack has an internal sleeve, check that it adds useful separation rather than unnecessary weight.

Water-Resistant Is Useful; “Waterproof” Needs Context

Family hikes do not always happen in perfect weather. A water-resistant exterior can help protect snacks, spare clothing and small personal items from light rain and damp ground.

But seams, zippers and openings can still allow water inside.

Unless the entire bag has sealed seams and a verified waterproof construction, pack important items in small waterproof bags or reusable zip pouches.

A lightweight rain jacket should also remain accessible instead of being compressed at the bottom.

Test the Backpack Before the Trail

Do not let the first real test happen halfway through a hike.

Pack the backpack with the intended water, snack and clothing. Adjust both shoulder straps evenly and secure the chest strap.

Then ask the child to:

Walk for ten minutes

Go up and down stairs

Bend down

Reach both arms forward

Remove and put the backpack on again

Watch the backpack rather than relying only on “It’s fine.”

Warning signs include:

The pack swings from side to side

Shoulder straps slide outward

The child leans forward

Straps leave deep marks

The bottom hangs well below the waist

The child repeatedly pulls at the straps

Water or other items shift noticeably

If the child needs to lean forward to support the backpack, the AAP advises that the load is too heavy. Remove items or move them to the adult’s pack.

Comfort Can Change After the Hike Starts

A backpack that feels comfortable at the trailhead may feel different after twenty minutes.

Check again shortly after starting:

Are the shoulder straps still even?

Has the chest strap moved?

Is anything pressing into the back?

Is the child changing posture?

Are they asking to remove the pack?

Treat the first part of the hike as a second fitting session.

If the child is uncomfortable, move equipment into the adult’s backpack. Carrying their own daypack should help them participate in the hike, not become a test they have to pass.

Include a Whistle

A whistle is small, light and useful for every member of a family hiking group.

The National Park Service specifically recommends considering a whistle for each person when travelling with children because it can help searchers locate someone who becomes separated. See the NPS Trip Planning Guide.

Attach it somewhere accessible and teach the child that it is emergency equipment, not a trail toy.

A whistle inside a zipped pocket is less useful than one the child can reach without removing the backpack.

A Simple Parent’s Checklist

Before choosing a kids hiking backpack, check:

Does it fit the child’s current height and torso?

Does it stay close to the back?

Are both shoulder straps adjustable?

Does it have a usable chest strap?

Is the empty backpack reasonably light?

Can the child reach or identify important items?

Does the water bottle stay secure?

Can an adult take over the bag easily?

Does the pack remain stable when the child moves?

Is there room for the child’s essentials without filling every pocket?

The best hiking backpack for kids should pass these tests before color, brand or extra features enter the decision.

The Best Backpack Is the One They Can Forget About

A good children’s hiking backpack should help a child feel involved.

They carry their own water, choose a snack and learn where their jacket belongs. The backpack becomes part of preparing for the trail.

But once the hike begins, it should fade into the background.

The best kids hiking backpack is not the one that carries the most. It is the one that fits well, stays light and allows the child to keep walking, looking and enjoying the day.
