Last summer, my 8-year-old son's first multi-day backpacking trip in the Sierra Nevadas started with me cutting corners on his gear, assuming he could "tough it out" like I did as a kid. I grabbed his old day-hike pack, a cheap hand-me-down adult sleeping bag, and shoes that were half a size too big "for growing into." Halfway through day one, the pack straps were digging into his shoulders so bad he cried, the sleeping bag left him shivering for 3 hours when the temperature dropped to 38°F, and we had to cut the 3-day trip short. He refused to even look at a backpack for 6 months after that.
That mistake taught me that kid-friendly backpacking gear isn't just "shrunken adult gear" --- it's built for their smaller bodies, shorter attention spans, and far lower tolerance for discomfort. Bad gear doesn't just make a trip miserable: it can turn kids off the outdoors for life. Over the past 3 years and 7 multi-day trips with my two kids (now 8 and 10), I've figured out exactly what to look for (and what to avoid) when packing for little hikers. And no, you don't need to drop $500 on custom gear --- most kid-specific sets are affordable, and you can find barely used sets on local hiking groups or resale sites, since kids outgrow it so fast.
The Backpack: Fit First, Features Second
The single most important piece of gear you'll buy for your kid, and the one most parents mess up. The #1 mistake? Buying a pack that's "a size too big so they grow into it." A pack that's too large throws off their center of balance, strains their developing back, and means they can't reach their own water or snacks without taking the whole thing off. Stick to these non-negotiable rules first:
- Capacity matches their size, not the trip length: Kids 6--10 need 15--20L for 2--3 day trips, 20--25L for 4--5 day trips; kids 10+ can handle 25--30L. No exceptions for "growing into it."
- Total pack weight (including their gear) should never exceed 10--15% of their body weight. A 50lb kid? Max 7.5lb pack.
- Look for padded, adjustable shoulder straps and a hip belt that sits on their hip bones , not their waist. Most kid packs have thin webbing belts that dig in; opt for one with at least ½ inch of padding on the belt to distribute weight evenly.
- Prioritize easy access: Side water bottle pockets they can reach without taking the pack off, a top lid pocket for their favorite found rock or pinecone, and no overly complicated zipper compartments they can't open on their own. Pro tip: Let them pick the pack themselves. My son spent 2 hours scrolling for a pack with a dinosaur patch, and he was so proud to carry it on our next trip, he didn't even complain when it rained.
Sleep System: Skip the Hand-Me-Downs
Adult hand-me-down sleeping bags are the second biggest cause of kid backpacking burnout. Kids have a higher surface-area-to-body-mass ratio than adults, so they lose heat 2--3x faster --- a sleeping bag rated for the same temperature as an adult one will leave them freezing. What to look for:
- Get a bag rated 10°F lower than the expected nighttime low. If the low is 40°F, spring for a 30°F rated bag, not a 40°F one.
- Skip adult-sized bags entirely. Extra space inside the bag means cold air circulates, and they'll be colder. Go for a size-specific mummy bag (they trap heat better) or a rectangular bag made for their height, not a "one size fits all" adult bag.
- A sleeping pad is non-negotiable. The ground saps heat faster than cold air, and a cheap foam pad or small inflatable pad will make the difference between a good night's sleep and 3 hours of shivering. Look for a kid-sized pad that's easy for them to roll up and carry themselves. Budget hack: A sleeping bag liner adds 10--15°F of warmth, costs $20, and is easy to wash if they spill juice or roll in dirt on the trip.
Clothing & Footwear: No Cotton, No "Growing Into" Shoes
Kids' body temperatures fluctuate way faster than adults, and their small feet are prone to blisters if shoes don't fit right.
- Ditch cotton entirely. Cotton stays wet when it's sweaty or rainy, and saps heat fast. Stick to moisture-wicking base layers even in summer, and pack 2 extra pairs of socks per day (wet feet = instant blisters for kids).
- Footwear is make-or-break. Never buy shoes that are "a size too big so they have room to grow." Too-big shoes cause blisters, tripping, and sore feet within the first hour. Get shoes that fit perfectly right now, with a thumb's width of space at the toe, and break them in for at least a week before the trip (wear them around the house, on short local hikes). For younger kids, Velcro straps are better than laces --- they can put them on and take them off without your help, which builds independence.
- Pack extra layers even if the daytime high is 70°F. Mountain and desert temps can drop 30 degrees after sunset, and a wet kid from a stream splash or rain will get cold fast. A lightweight fleece and waterproof shell take up almost no space in their pack, and save you from a miserable, cold night.
Hydration & Nutrition Gear: Make It Easy For Them To Use
Kids forget to drink water when they're having fun, so don't make it hard for them. Skip the heavy, bulky adult water bottles --- get a 1L hydration reservoir that fits in their pack's side pocket, or a small, lightweight BPA-free bottle they can lift and open themselves. Set a rule: take a sip every 15 minutes, even if they say they're not thirsty. For snacks, get a small, easy-open pouch they can reach without taking their pack off. Let them pick their own snacks for the trip (within reason) --- if they get to pack their favorite gummies, pretzels, and fruit snacks, they'll actually eat them, instead of complaining every 10 minutes that they're hungry. Skip complicated snack packaging with hard-to-open lids; you don't want to stop every 5 minutes to help them open a granola bar.
Small Comfort & Safety Gear That Makes A Huge Difference
You don't need a bunch of extra gear, but these small items will make the trip better for everyone:
- A kid-sized headlamp, not an adult one that's too heavy and slips off their head. Let them pick one with a fun color or glow-in-the-dark feature --- they'll fight to be the one to turn on the camp lantern at night.
- A small, lightweight first aid kit tailored to them: blister pads in their size, their favorite dinosaur band-aids, anti-itch cream for bug bites, and a tube of their favorite lip balm (their lips chap 10x faster than yours).
- Ear plugs for sleeping. Campgrounds are loud, from other hikers to distant dogs, and kids have a much harder time falling asleep with background noise.
- A small, lightweight kid-sized camp chair (most weigh less than 2lbs). Sitting on the cold, rocky ground to eat lunch or roast marshmallows gets old fast for little legs, and a cheap $20 camp chair will make them feel like they have their own special spot at camp.
- Let them bring one small comfort item: a stuffed animal, a favorite picture book, a small toy. It takes up almost no space in their pack, but makes the backcountry feel like home when they're tired or missing their own bed.
What To Avoid At All Costs
- Don't buy gear they'll "grow into." A too-big pack, too-big shoes, or too-big sleeping bag will make the trip miserable, full stop. Buy gear that fits them right now, and replace it when they outgrow it.
- Don't cheap out on the sleep system. A bad sleeping bag and pad are the #1 reason kids hate multi-day backpacking. Spend the extra $30 on a good kid-specific bag and pad --- it's worth it.
- Don't bring gear that's too complicated for them to use. If a stove has 10 knobs they can't figure out, or a water filter is hard for them to operate, you'll be doing all the work for them, and they won't learn anything. Opt for simple, kid-friendly tools if they're old enough to help with camp chores.
- Don't overpack their bag. Stick to the essentials, and let them carry their own water, snacks, and extra layers. The goal is to build their confidence and independence, not to carry their stuff for them.
After fixing all our gear mistakes, we did a 4-day trip in the Colorado Rockies last fall. My son carried his own 9lb pack, slept through the night in his dinosaur sleeping bag, hiked 6 miles a day without complaining, and even helped filter water and set up the tent. Halfway through the trip, he turned to me and said, "This is way more fun than Disneyland." That's the real goal, right? Not to check a multi-day trip off your bucket list, but to build a love of the outdoors that lasts a lifetime. The right gear doesn't make the trip easy --- it makes it fun, for both of you.
