How to buy a backpack


In the same way a pair of too-tight hiking boots can ruin your day on the trail, an ill-fitting backpack can easily turn your fun trek into a nightmare march. But it doesn’t have to be that way.

The Gear Guy is currently researching new models and writing an update to this article. Watch for his updated tips and reviews in the April 2017 issue of Boys’ Life.

Backpacks come in many different shapes and sizes with tons of adjustability to fit just about any type of backpacker. The trick is finding the right pack for your body and the type of backpacking you have planned.

Your Gear Guy is here to help get you on the trail and easily shouldering that load.


To pick a pack that fits you correctly, first measure your torso length. Have a parent use a soft seamstress tape to measure the distance from the base of your neck straight down to your hipbone. Now find a pack that fits that sizing. Most youth backpacks have adjustable harnesses that accommodate a range of torso lengths.


The next measurement you need is your waist size. About 70 to 80 percent of the weight of your pack will be supported by your hips, so getting a hip belt that fits is key. Most hip belts offer a lot of adjustment, and some packs provide removable/swappable hip belts so you can size appropriately.

Deuter Fox 40 and Outdoor Products Dragonfly

Deuter Fox 40: ($109, Capacity: 40 liters/2,440 cu. in. Weight: 2 lbs. 14 oz. Adjusts to fit torso range of 11″-18″. The Fox 30 ($99) fits smaller guys. Outdoor Products Dragonfly External Frame Pack: ($67, Capacity: 45 liters/2,780; Weight: 3 lbs. 10 oz. Adjusts to fit torso range of 15″-18″.


There are two basic types of backpacks: External frame packs use a metal framework on the outside to support the load, while internal frame packs have their support structure hidden inside the pack like a skeleton.

Internal frame packs are more formfitting, bringing the load closer to your body for more stability and better performance on tight trails.

External frame packs are cheaper and provide better airflow between your body and the pack, while also offering more flexibility for packing bulky items.

When choosing between internal and external frame packs, make sure to consider the size of your sleeping bag. You might buy an internal frame backpack only to get home and realize there’s no way your sleeping bag will fit inside. If you have a lightweight, compressible sleeping bag, it should fit well in most internal packs, but if you have a big, bulky sleeping bag and won’t be getting a new one anytime soon, consider an external frame pack. It’ll give you plenty of room for strapping on a large sleeping bag.

Gregory Wanter 50 and Kelty Yukon 48

Gregory Wander 50: ($179, Capacity: 50 liters/3,051 cu. in. Weight: 3 lbs. 6 oz. Adjusts to fit torso range of 13″-18″. The Wander 70 ($199) fits larger guys. Kelty Yukon 48: ($170, Capacity: 48 liters/2,900 cu. in. Weight: 4 lbs. 13 oz. Adjusts to fit torso range of 13″-19″.


When it comes to backpacks, bigger is not always better. The amount of gear a pack can hold is measured in either liters or cubic inches. Your pack’s carrying capacity should mirror the type of trip you’re planning, whether it’s a simple overnighter, a full-on seven-day backpacking trip or something in between.

An internal frame pack with a capacity of about 40 to 60 liters would be a versatile size for most guys and perfect for a multiday trip. Of course, the smaller you are, the smaller the bag you should carry, so a 35- to 50-liter pack might be fine for you. You can also get by with a lower-capacity external frame pack since there’s lots of extra space to strap on a sleeping bag and pad.

Remember, just because you have space left over doesn’t mean you should fill your pack to the brim. Keep your load within 20 to 30 percent of your bodyweight. Carry just the essentials and your pack will be much lighter, you’ll use less energy getting down the trail and you’ll probably have a lot more fun, too!


They’re nice but not necessary. Comfort and fit are most important. Beyond that, look for a pack with compression straps that help keep your load from flopping around when the pack isn’t filled up. Some packs are top-loading only while others have side zips that let you access your stuff from several places. You’ll also find bells and whistles like built-in sleeves for hydration packs and lots of exterior organization pockets for easy access to what you need on the trail.


Ask around to see if friends have a backpack you can borrow. This will help you get a feel for what type of pack you want to buy and how it should fit. Some outdoor shops even rent backpacks, so you can try before you buy.

Osprey ACE 38 and Mountainsmith Youth Pursuit

Osprey ACE 38: ($140, Capacity: 38 liters/2,319 cu. in. Weight: 2 lbs. 6 oz. Adjusts to fit torso range of 11″-15″. The ACE 50 ($160) fits larger guys. Mountainsmith Youth Pursuit: ($140, Capacity: 45 liters/2,746 cu. in. Weight: 3 lbs. 6 oz. Adjusts to fit torso range of 13″-17″.


Before you go pack shopping, set a budget. Sure, you’ll see lots of tricked-out big brand-name backpacks in the $400-plus range, but you certainly don’t need to spend that much. The $150-$200 range will get you a nice pack that should last for several years or more.


Nothing beats a Scout shop or outdoor specialty store with knowledgeable sales people who can help with fit. Try on several packs, have them adjusted appropriately, then fill them up with gear and wear them around the shop for 15 to 20 minutes. The key is to simulate the kind of weight you’ll be carrying. So fill up the pack with 20 to 30 pounds of tents and climbing ropes from the store or bring your own gear. While buying online can save you some cash, you won’t be able to try out the pack before you buy it.

L.L. Bean Youth White Mountain Pack

L.L. Bean Youth White Mountain Pack: ($159, Capacity: 50 liters/3,051 cu. in. Weight: 4 lbs. 11 oz. Adjusts to fit torso range of 14″-16″.

REI Passage 65

REI Passage 65: ($159, Capacity: 65 liters/3,967 cu. in. Weight: 4 lbs. 4 oz. Adjusts to fit torso range of 15″-19″. The Passage 38 ($100) fits smaller guys.

All prices are MSRP — manufacturer’s suggested retail price. You can often find better deals in stores or online.

  1. Is it worth my money to buy the Teton Scout 3400 backpack?

    • Although the Teton 3400 is a bit heavy and has too many straps for a 3400 c.i. pack it is a good starter for a youth especially at the price. I would not recommend carrying any more than 30 lbs with it, though. The shoulder straps and hip belt are too soft to provide a lot of support. Good for a weekend trek.

  2. I have the Osprey Ace and it is great. My mom got it for me and it has been all over. The shoulder straps hook to back board that you can move up and down depending on how tall you are. It comes with a rain cover too.

  3. I bought a high sierra titan 65 perfect

  4. i can stuff my backpack a lot try buying and rei they’re really good.

  5. I want to buy a High Sierra Titan 65 Internal Frame Backpack, but I am afraid that it will be to big. What should I do?

  6. High Sierra is one of the best packs I had a small one for three years now I have the swerve nothing wrong with the first just a little small. swerve is perfect.

  7. I am getting foxhound 50 pack.

  8. I’m thinking about getting the osprey aether 85 ,is that a good pack? Please respond.

  9. Heading to Philmont next year; reducing my pack weight by purchasing a “Go-Lite” 45. Weighs only 2.1# and uses your mattress pad as the back support, really cool; works great. This pack holds the same as my old pack but weighs 4.1# less. costs $99.00. This is a pack for smart scouts; tough-light-inexpensive-roomy.

  10. I hope you’re right knife expert because I’m getting the Teton 4000

      Nice dude! let me know how it works for ya.

      I have hiked over 75 Northern Idaho miles with this pack. I bought it at a outdoor store for $70. Most stores don’t sell their products at retail price because the retail price is always too expensive.

      Go to amazon and look at the reviews… and at the price. I have hiked over 75 miles with this pack and know what i am talking about.

    I’ve packed on three continents, on lots of terrain. You’ve mentioned some good gear, but if you’d like good design and very good value, check out Alps Mountaineering. Prices are competitive and they offer very special discounts for scouts and scouters.

    • I can attest to the value, quality and customer service of Alps. Call and ask for their Scout Direct pricing. Quality is much superior to the Teton brand and very comparable to the big name brands. I am a Scout Master and personally own 5 Alps internal frame backpacks. The Caldera 4500 is my favorite. I also own external Kelty(s), Gerry(s), CampTrails and Jansport.that I let my boys use. The external Alps are a knock off of the Kelty Trekker.

  12. Where can I buy some backpacks?

  13. I’m looking into a kelty yukon 48 external frame. Is that a good backpack?

    Any osprey you can use them then sell them like crazy

  16. I have the Outdoor Products Stargazer 8.0.It has a lifetime warranty and is made of rip stop has a good amount of space has a removable internal frame and a comfortable padded hipbelt

  17. If you are willing to pay alot go with gregory baltoro 75. It is super comfy and feels like part of you. It has enough space for a weeklong winter trek. Expensive though…

  18. The North Face Terra 65 is a very good pack for $170. I took it on a week long trip in Utah’s High Uintas Wilderness and it had plenty of room for all my gear and was very durable and comfortable.

  19. I got the Osprey Ace for Christmas. Great Pack!! 🙂

  20. i’m looking to buy a backpack for under 70 bucks.

  21. i need a good internal frame pack but it needs to be in the high 50s or else my parents wont let me get it. please help me now

      As usual I recommend the Teton Sports Explorer 4000 or the teton scout 3400. both are cheap but extremely reliable!

  24. nice

    I just got a 4000 by Granit Gear, it’s awesome. Thanks for the tip.

  26. My youngest son (17- Eagle scout ) got a Duluth Pack 2800 ci We are minimalists, now he uses it all the time, school too. Nice to see him figure things out. Multi-use packs are great .This brand is guaranteed for life too. Find that anywhere else!

  27. I got a Kelty Coyote and I really like it and it holds enough, but if I was buying a new one I would either by the Kelty Red Cloud (The Coyote’s big brother that also has a sleeping bag compartment) or a Kelty Yukon (So I could strap stuff to the outside easier)

  31. I like the osprey 68, I found it for $150 my parents still think its too much. What would you suggest I get?

  32. I need a good cheap(hopefull) backpack.any ideas?

    • Knife Xpert 157 (aka Chad 101) // September 6, 2012 at 9:02 pm // Reply

      I would highly recommend Teton Sports Explorer 4000 or Scout 3400. They are fairly inexpensive ($70-$65 for the Explorer and $50-$45 for the Scout) they are made of RipStop and are very good packs.

  35. Sorry chad that was my bro who doesn’t even have a teton. Which is better out of the osprey range: the aether 70 or the kestrel 68? no other packs requested

      Thats ok bro. I would probably go with the Kestrel 68. But they are both Ospreys and Ospreys are SUPER good quality so either one would work great.

    Try Granit Gear, If it’s good enough for the military it’s tough enough for a scout. Made in the USA too.

      I have a feeling your not telling me the whole story but here’s some buyers advice… buy it from a store so you can try it on and look over it for any deformities, or if you really think a pack made of RipStop (one of the toughest fabrics) can just fall apart for no reason then dont buy it again, its your money and your choice of what to do with it. But as for me, Teton is my number one backpack company.

      • Just face it man! Tetons are mostly badly made!

        I have the 4000 and my brother and another friend have the SCOUT 3400 and none of our packs have broken in any way yet. are we talking about the same Teton? maybe you got a bad batch or something… all I know is if I know two other people that have packs just like mine and have been very rough with them for over a year then you are wrong Tetons are not mostly bad you just had bad luck that all.

    Alps Mountaineering and Kelty both make great packs of all sizes. I like the internals best.

  42. Chad 101 you are incorrect! I brought the pack back and got a new one and that one fell apart as well. I then swapped it out for a refund. Tetons suck! Long live LL Bean and REI!

        dude, HOW on EARTH did you break it! It is made of RipStop and is an EXTREMELY tough pack! did you stab it with your pocket knife or what? I beg you try the 4000 just one more time… and buy it from a different seller.

    Look at the Kelty series; They have super nice waist belts and superior back meshing to help keep you drier in hot weather. The are also very light yet strong enough for any outing. I prefer the comanchee model, 3# 6 oz.with 6 compartments.

    What is a good backpack for the AT trial and Philmont

  45. Internal frames are the best for off trail hiking of mountaineering.

  46. I going to buy the Rei pasage 65 backpack and I can’t find a pack I like better. I am going to philmont this summer and that hip belt looks real nice.

  47. I just bought an Osprey Kestrel 58 Backpack for my son. Just wanted to add that Osprey will repair or, if they can’t repair, replace any of their backpacks for free, no matter how old the pack is! Dick’s wanted me to buy a one year warranty on a Northface pack that wasn’t as nice. If Osprey has that kind of warranty, their packs have to be good! The built in rain cover sold me on it too.

        Dude give Teton another chance! My explorer 4000 is very good quality and has lasted me about 50 miles of rough hiking and im sure it is going to last me hundreds more! Maybe there was a defect in your pack… whatever the cause I encourage you to try them again. If they work for a experienced off trail Idaho hiker like me, they can work for you!
