Getting kids excited about hiking starts with making them feel like real participants — not passengers. When a child has their own backpack, sized for their body and packed with their own snacks, water, and layers, the trail becomes their adventure too. It’s one of the simplest ways to shift hiking from something they tolerate to something they ask for.

The challenge is finding the right pack. Kids’ bodies are proportioned differently from adults, they grow fast, and the wrong pack — too heavy, too large, or with poorly adjusted straps — creates discomfort that ruins the experience. A properly fitted, age-appropriate hiking backpack makes miles easier and keeps the focus where it belongs: on the trail.

This guide breaks down the 10 best hiking backpacks for kids by age group — from first-time toddler packs to serious overnight rigs for older kids — all available on Amazon. We’ve organized them to help you find the right match for your child’s age, size, and the kind of hiking your family does.

For parents still carrying younger children, check out our guides to the best hiking backpack carriers for toddlers and best hiking backpack carriers for babies.

How Much Should a Kid Carry?

Before the picks, one rule that applies at every age: kids should never carry more than 10–20% of their body weight in a backpack. A 50-lb child should carry no more than 5–10 lbs. A 90-lb child, no more than 9–18 lbs.

Exceeding this puts real strain on developing spines and joints, especially on uneven terrain over long distances. Start lighter than you think necessary, and let them ask for more responsibility as they build strength and trail fitness.

Ages 3–5: First Trail Packs

1. CamelBak Mini M.U.L.E. — Best First Hydration Pack for Toddlers

The CamelBak Mini M.U.L.E. is the gold standard for young kids’ first trail pack. Designed specifically for small bodies with a 13-inch back length, it fits kids from around age 3 without swallowing them. The included 1.5-liter Crux reservoir delivers hands-free hydration through CamelBak’s reliable bite valve — which young kids can operate independently without help from parents.

The back panel uses breathable air mesh that keeps little backs cool on warm days, and the design is light enough that even a toddler barely notices it’s there when loaded appropriately. Multiple reflective accents improve visibility on the trail, and a safety whistle on the sternum strap is a genuine safety feature parents appreciate.

Storage is intentionally minimal — a main pocket for a small layer and a front pocket for snacks. This is a hydration pack first and a gear carrier second, which is exactly right for the age group. Kids this age don’t need to carry much beyond their water and a snack.

Best for: Kids ages 3–7 who need their first independent hydration pack for day hikes.

2. Deuter Pico — Best Toddler Daypack Without Hydration

Not every young hiker needs a hydration bladder system. For toddlers who are happy with a water bottle and just want to carry their own stuff, the Deuter Pico is the best introductory pack available. It’s lightweight, brightly colored, durably built, and sized perfectly for small bodies.

The chest clip is the standout feature for young kids — it keeps the shoulder straps in place on narrow shoulders without constant adjustment, which makes a real difference in trail comfort for children who haven’t grown into standard strap spacing yet. At 5 liters there’s room for a small snack, a thin layer, and whatever treasures they collect on the trail.

The Deuter Pico is also versatile beyond hiking — it works as a daycare bag, a park bag, and an everyday carry that gets years of use. For families who want a first pack that builds the habit before investing in technical trail gear, this is the smartest starting point.

Best for: Toddlers ages 2–5 who want their own pack without the complexity of a hydration system.

Ages 5–9: Growing Trail Kids

3. Osprey Jet 18 — Best All-Around Kids’ Hiking Pack

The Osprey Jet 18 is the step up from a toddler pack to a real hiking backpack — and it makes the transition well. Designed for kids ages 5–11, it features Osprey’s adjustable harness system with a 4-inch torso adjustment range that grows with your child through multiple seasons without needing replacement.

The AirSpeed mesh back panel creates genuine ventilation between your child’s back and the pack — a feature that makes a real difference on warm hiking days when kids overheat quickly. The hydration sleeve fits a 1.5-liter reservoir (sold separately), and dual side mesh pockets handle water bottles if you skip the bladder setup.

Seven exterior pockets give kids the organizational satisfaction of finding their own snacks and gear without asking parents — a small thing that builds trail independence in a meaningful way. At 18 liters, there’s enough room for a day’s worth of layers, food, and first aid without overloading a small frame.

Best for: Kids ages 5–11 who need a well-ventilated, adjustable daypack for regular trail use.

4. Ivygreen Kids Hydration Backpack — Best Budget Kids’ Hydration Pack

The Ivygreen Kids Hydration Backpack is a solid budget alternative to the premium CamelBak and Osprey options — delivering hands-free hydration with a 1.5L water bladder included at a price that makes it easy to gear up multiple kids without breaking the family budget.

Designed for both boys and girls, the pack fits comfortably on smaller frames with padded shoulder straps and an adjustable sternum strap that keeps the pack planted during active movement on the trail. The 1.5L bladder is appropriately sized for half-day to full-day hikes in the 5–10 age range — enough water to keep kids hydrated without adding unnecessary weight to a small frame.

Organization goes beyond just hydration — the main compartment handles a snack, a thin layer, and small trail essentials, giving kids the independence of carrying their own gear alongside their water. Multiple exterior pockets keep frequently accessed items within reach without opening the main compartment.

For families who want to get two or three kids geared up with their own hydration packs without spending $50–65 per child on a CamelBak, the Ivygreen delivers reliable trail performance at a more accessible price point.

Best for: Budget-conscious families who want a complete kids’ hydration pack for boys or girls without paying premium brand prices.

5. MOUNTAINTOP 12L Kids Hiking Backpack — Best Budget Kids’ Daypack

The MOUNTAINTOP 12L is one of the most practical budget kids’ hiking daypacks on Amazon — sized right for ages 4–10, durable enough for regular trail use, and priced well under $40 so parents can gear up multiple kids without the premium brand price tag.

At 12 liters it hits the sweet spot for young hikers — enough volume for a water bottle, snacks, a thin layer, and small trail items without overloading a small frame. The waterproof exterior handles light rain and trail splashes without soaking through, and the padded shoulder straps distribute the load comfortably across narrow shoulders.

Dual side mesh pockets handle water bottles for easy independent access — kids can grab their own water without stopping or asking for help, which builds trail confidence and independence. A sternum strap keeps the pack planted during active movement without slipping around.

For families who want their kids to have their own pack for the trail without spending $50–85 on an Osprey or Deuter, the MOUNTAINTOP 12L delivers reliable everyday trail performance at a price that makes it easy to say yes.

Best for: Budget-conscious families who want a properly sized, durable kids’ daypack for ages 4–10 without premium brand prices.

Ages 8–12: Serious Young Hikers

6. Osprey Ace 38 — Best Kids’ Pack for Day Hikes and Overnights

The Osprey Ace 38 is the benchmark kids’ hiking pack for the 8–12 age range — a pack that delivers genuine technical performance in a size built for smaller bodies. The adjustable torso system accommodates 11–15 inch back lengths with 4 inches of adjustability, meaning it grows through multiple seasons without requiring replacement.

The AirSpeed mesh back panel provides real ventilation, and the hip belt is padded and functional — not decorative — making it one of the few kids’ packs that actually transfers weight to the hips the way adult packs do. Hip belt pockets add the quick-access storage for snacks and trail items that kids consistently love.

At 38 liters there’s room for a sleeping bag, a change of clothes, and a full day kit — making it the first pack on this list genuinely suited for overnight adventures. A rain cover stores in a dedicated bottom pocket and is ready when weather moves in unexpectedly. For families planning their first overnight trip with kids, the Ace 38 handles the load without overwhelming a young hiker.

Best for: Kids ages 8–12 who are ready for serious day hiking or their first overnight backpacking trips.

7. Gregory Wander 50 — Best for Older Kids on Multi-Day Trips

The Gregory Wander 50 is the pack for older kids — typically 10 and up — who are tackling genuine multi-day trips and need the volume and suspension to carry a real overnight kit. The adjustable torso system and hip belt grow with the child, and the padded suspension transfers weight to the hips in a way that makes 25–30 lbs manageable over long distances.

Panel-style access through a U-shaped front zipper makes packing and unpacking efficient without emptying the whole bag to find buried items — a practical advantage on trail when you need to access gear quickly. The stretch front pocket provides easy access to a rain layer or snack without opening the main compartment.

Durability is where the Wander 50 earns its price — Gregory builds packs to last, and this one is designed to handle years of hard use across multiple seasons of family adventures.

Best for: Older kids ages 10–15 who are ready for multi-day backpacking with a full overnight kit.

8. Deuter Junior 18 — Best European-Style Kids’ Pack

Deuter’s Junior 18 brings German outdoor engineering to a kids’ daypack — which means attention to fit detail, material quality, and ergonomic design that most budget kids’ packs skip. The back system uses Deuter’s Aircomfort contact padding that creates ventilation channels across the back panel for better airflow than a flat foam alternative.

The Airstripes shoulder straps are designed specifically for narrower, underdeveloped shoulders — angling them inward to distribute load without digging into the neck or arms. At 18 liters it’s the right volume for full-day hikes in the 7–12 age range, and the compact, well-organized design keeps gear accessible without clutter.

A hydration-compatible sleeve accommodates a standard reservoir for kids who want the hands-free hydration option alongside traditional water bottle pockets. The build quality gives it multi-year durability even with the kind of daily use that kids apply to their gear.

Best for: Kids ages 7–12 whose parents want European build quality and ergonomic fit in a mid-size daypack.

Ages 12+: Teen Transition Packs

9. Osprey Ace 50 — Best Transition Pack for Tweens and Teens

The Osprey Ace 50 is the bridge between a kid’s pack and an adult pack — sized for older children and teens with torso lengths of 13–18 inches, covering the transition years when most young hikers outgrow dedicated kids’ gear but aren’t quite ready for full adult sizing.

All the features that make the Ace 38 exceptional scale up here: AirSpeed ventilation, adjustable torso and hip belt, hip belt pockets, and a rain cover included. At 50 liters there’s genuine capacity for multi-night trips — enough for a tent, sleeping bag, and clothing without compromising organization.

The weight at 2.9 lbs is on the heavier side for a kids’ pack, but for teens ready for serious backpacking that weight is justified by the suspension capability and volume. This is a pack that grows into an adult’s trail partner with a young hiker.

Best for: Tweens and teens ages 12–16 transitioning from kids’ gear to adult-level trail performance.

10. Kelty Coyote 65 — Best Budget Overnight Pack for Teens

The Kelty Coyote 65 is the go-to budget overnight pack for teens ready to carry a full kit on multi-day trips — delivering serious load-hauling capability at a price well below premium brands. Kelty has been building trusted, affordable outdoor gear for decades and the Coyote is their flagship expression of that.

The Fit Pro torso adjustment system dials in fit on the fly without tools — important for teens whose proportions change quickly and who need a pack that keeps up with growth spurts. The Amp Flow ventilated back panel keeps airflow moving on warm hiking days, and the aluminum frame stays provide real load support for heavier overnight kits.

Organization is a genuine strength — Kelty Signature wing pockets, dual front zippered pockets, daisy chains, water bottle pockets, and a sleeping bag compartment keep gear sorted and accessible without digging through the main compartment. The J-zip top loading access makes packing and unpacking fast on the trail.

At 65 liters there’s ample room for a full overnight kit — tent, sleeping bag, food, and clothing — with enough extra volume for teens who haven’t mastered pack minimalism yet. For parents who want to set a teen up with a complete, functional overnight rig without spending $200+, the Kelty Coyote delivers everything that matters. As teens grow into adult sizing, our best hiking backpacks for tall men guide is a natural next step when they’re ready to transition to a full adult pack.

How to Size a Kids’ Hiking Backpack

Match volume to age and trip type. Ages 3–5: 5–15 liters. Ages 5–9: 12–20 liters. Ages 8–12: 20–40 liters. Ages 12+: 40–55 liters. These are guidelines — always match the pack to the trip, not just the age.

Torso length matters more than age. Just like adults, kids need packs matched to their torso length — not their age or height. Most quality kids’ packs list their torso range in the specs. Measure from the C7 vertebra at the base of the neck to the top of the hip bones.

The hip belt should actually function. On quality kids’ packs, the hip belt is padded and wraps around the actual hip bones to transfer weight. A decorative hip strap that sits on the stomach doesn’t transfer weight and doesn’t help. Make sure the hip belt sits correctly before hitting the trail.

Adjust before the hike, not on it. Take 10 minutes at home to dial in the torso length, hip belt, shoulder straps, and sternum strap before the first trail day. A properly fitted pack on a child makes hours of hiking comfortable; a poorly fitted one makes the first mile miserable.

Start light and build. On a child’s first hike with their own pack, put almost nothing in it. Let them feel the independence without the load. Add weight gradually over subsequent hikes as they build strength and enthusiasm for carrying their own gear.

Final Thoughts

The right kids’ hiking backpack is one of the best investments a hiking family can make. It shifts the dynamic from parent carrying everything to a genuine team effort — and kids who carry their own gear develop a sense of ownership over the adventure that keeps them engaged and excited about the trail.

For toddlers just getting started, the CamelBak Mini M.U.L.E. and Deuter Pico are the standouts. For the core 5–12 age range, the Osprey Jet 18 and Osprey Ace 38 lead the list. And for teens ready to carry a full overnight kit, the Osprey Ace 50 and REI Passage 55 make the transition from kids’ gear to serious backpacking seamless.
