Best Hiking Backpack For Kids

Choosing a kids' hiking backpack comes down to matching torso length and load capacity to what the child can comfortably carry, not to liter size or character branding alone.

What size backpack does my child need for hiking?

Most young kids need a small daypack in the 8 to 15 liter range, sized by measuring torso length from the C7 vertebra to the iliac crest rather than by age, height or shoe size. A 4 to 6 year old typically fits an 8 to 12 liter pack holding little more than water and a comfort item, while a 7 to 10 year old carrying a real share of the ten essentials usually needs 12 to 18 liters.

What features matter most on a kids' hiking backpack?

The features that matter most are a light overall pack weight, buckles and zippers a child can operate independently, a chest strap to keep shoulder straps in place during scrambling, and a hydration sleeve if the child will carry a reservoir. A structured hipbelt matters less on a young kid's daypack than on an adult pack, since loads stay light enough that the shoulders can reasonably carry most of the weight.

• Pack weight: as light as possible empty, since every added ounce competes directly with the child's own load allowance
• Closures: buckles and zipper pulls sized and shaped for smaller hands
• Chest strap: keeps shoulder straps from sliding off narrow shoulders during scrambling or stream crossings
• Hydration compatibility: a reservoir sleeve and drink-tube port for kids old enough to manage a bite valve
• Reflective trim or a whistle: small safety features that don't affect fit but add visibility and a way to signal if separated from the group

Daypack or hydration vest for young kids?

A simple daypack suits most young hikers carrying only water, a snack and a layer, while a hydration vest — a minimal harness built around a reservoir with little to no storage — suits very young kids who need almost nothing else on their back. Vests weigh less and interfere less with arm movement, but they can't hold a rain shell, first-aid kit or extra layers the way even a small daypack can.

How much should a kids' hiking backpack weigh empty?

A kids' daypack should weigh as little as possible empty, typically well under a pound for packs in the 8 to 15 liter range, since a heavy empty pack eats directly into a young child's already-limited safe load. Frameless or minimally framed construction is standard at this size for that reason, unlike adult daypacks where a frame is often worth the added weight for comfort.

What safety features should a kids' pack have?

Useful safety features on a kids' pack include reflective trim for visibility on shaded trail or near roads, a whistle built into the sternum-strap buckle for signaling if separated from the group, and a chest strap that keeps the pack secure during scrambling or creek crossings. None of these substitute for supervision, but they're reasonable, low-cost additions worth checking for when comparing packs.

Honest trade-offs when choosing a kids' pack

The honest trade-off is between a pack a child will actually want to wear — often driven by color or character branding — and one built with the lighter weight and better-fitted suspension that makes hiking comfortable. The best outcome usually comes from narrowing choices to packs that fit correctly and weigh little, then letting the child pick among those rather than starting from appearance and hoping the fit works out.
