    Go get 'em, tiger.

    Maybe your cute little monster isn't ready for a full sized pack just yet, but she can still load up the Osprey Ace 50 Kids' Backpack and lead you down the trail. The Ace packs the features of Osprey's adult packs into a size that's designed to fit kids up to 14 or so, and it has adjustable shoulder straps so your kid won't outgrow it in 16 hours. All the extras are there too, like a loop for her ice axe or fishing pole, an attachment for trekking poles, an integrated rain cover, and compression straps to lock the whole thing down.

    • Adjustable shoulder straps
    • Fit-on-the-Fly adjustable passed hip belt
    • Ice axe/fishing pole loop
    • Stow-on-the-Go trekking pole attachment
    • Stretch mesh front and side pockets
    • Removable lid with zippered under-lid pocket
    • Compression straps
    • Integrated rain cover
    • Item #OSP002F

    This pack grew up with me

    • Familiarity: I've put it through the wringer
    • Height: 5'9"
    • Weight: 160lbs

    My dad got the 48L version of this pack for me when I first joined Scouts many years ago. I compared it to the newer 50L and there are a few updates , but I still feel I can speak to the basics that make this pack great.

    Great airflow in the back panels, zip pockets on the hips is a great storage place for an inhaler and other accessories, the stretchy side pockets hold a water bottle easily, and there's even a raincover!

    This Osprey pack has stood up to hundreds and hundreds of miles of hiking, backpacking, and travel. I retired it with a backpacking trip around Europe during college. The torso length had tons of room for adjustment as I aged. The Ace series ideally will last until around the age of 16, but it fit me at age 21 just fine at 5'9 and 160lb. If it works, it works. I can even pass the pack down now as Osprey has a lifetime warranty.

    Kids are spoiled

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Ace 50
    • Height: 4'9"
    • Weight: 98lbs

    I recently bought this for my 10 year old. Somehow my kids have ended up very spoiled. I never had a pack like this when I was 10...or 30. My son recently expressed desire to start backpacking with me and after shopping around didn't like any of the cheaper options. I recently upgraded to an Osprey Aether AG 85 and loved it so getting him an Osprey seemed like the way to go. We haven't used it other than some day hike testing but initial impressions are very positive. It is 100% as well made and constructed as my adult pack. The torso and belt adjustments are very simple and well engineered. I wish I'd had anything this nice for backpacking when I was young.

    Seems to be the best option available

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size
    • Size Bought: Med
    • Height: 4'10"
    • Weight: 90lbs

    We got this for my step son for Christmas. He's10 and a little small for his age. In all the packs he tried on previously he was right in between sizes. What I like about this pack is the wide range of adjustment. I wanted to get him a back to last him into his teens and this was the only option I could find. He loves all the little pockets. Esp. the waist belt pockets for easy to grab things. We haven't had a chance to really test it out on the trail yet as the weather is not yet forgiving for his taste but I have high hopes that it will work very well. The only complaint he has had is he is not super fond of the color. It would be nice if each size had a couple color options.

    Great adjustable pack

    My son loved this pack after using some others. His attitude of backpacking changed drastically and he was so much more energetic on the hike up to the campsite than the other kids after 10 miles. He thanked me for getting him the pack as his 2 mile treks with other packs were less than fun.

    "This is awesome!"

      Says the 11 year old! Music to my ears! The Ace series is fantastic and fit my son well. We were long overdue for a backpacking trip, and the Ace made it easy. In this picture, he has on the Ace 38. But know that even if you go up in volume to the Ace 50 or 75, it has the same fit. Great adjust ability for this growing kid.

      Now that he is older, I am moving him into the larger volume Ace packs so he can carry all his own stuff!

      PS - no matter what I do, the image is sideways. Sorry!

      "This is awesome!"

      There is no perfect answer...

      • Familiarity: I've used it several times

      I’ve looked and looked for internal frame packs for my kids... The issue is the suspension - most importantly the hip belt and how it transfers weight from the bottom of the frames stays (rods) to the hip bone... My issue - none of these packs do it well in a size I need in torso and waist for my kids. The Ace 50 is a great pack: the weight is where you want it to be considering your kids are gonna carry between 12-20lbs... features are fine but the suspension ...ugh!... not terrible but really not much better than the rest. As expected 5 miles into day as the foam and material warmed up the suspensions started to sag on to my kids butts and they were not happy. On prior trips they carried REI Passage 40's - while a heavier pack by about a pound the suspensions were much better... BUT - they no longer make the 40's... only the 65's... which is too much volume for my kids... Murphy's Law.

      Hey there Sam, Leta with Osprey here. I am sorry that your kids had a not-so-great experience with this pack. I am wondering if everything was positioned right for them? My son (11) used the pack and had a great experience, except for the weight got "old" and he just wasnt used to wearing a pack. I will send this feedback over to my friend and the owner and designer at Osprey, Mike Pfotenhauer.
      I really appreciate you taking the time to write,

      Leta Kalfas -
      Thank you for your comment... Unfortunetly yes.. the pack was adjusted and fitted perfectly. 10 yeas in the industry selling and fitting Gregory and Dana Design Packs (Yes it was a bit ago) I know what I'm doing... Its a good pack but there is no active transfer of the load from the bottom of the stays/frame to the side (iliac crest) of the hip bone. The waist belt has no structure to it... like two basset hound ears... and the pack bag itself seems disproportional. Fully loaded the 'volume' of the pack (for a small torso kid) is too wide... I feel it needs to be narrower/taller - Most kids are going to be 'on' trail and the ability to get prevent the weight from sitting low is challenging in a pack that is more of a fat sausage and less of a longer hot dog... if you get my drift.

      Hi Leta,
      I would be interested to hear what the designer has to say. We just got the Ace 50. I bought it for my 11 y\o for Boy Scouts. I bought the Osprey because I love my Atmos an actually love all of my Osprey Packs. Were just doing a short hike next week, but November will be a longer one. A lot of the scouts have these PACS, they use them on a 12 day trip out West. Will have to check the model, I know they are 50's. On Inspection, Pac looks great...guess we will have to see...

      What size hydration reservoir works with this pack?

      Hey Cheryl!

      The Ace series is compatible with Osprey Hydration reservoirs up to 3L's in size. Honestly they should work with pretty much any reservoir you already have as well, as the reservoir area offers a fairly universal fit. Give us a call if you already own a reservoir you're concerned about and we'll help you determine if it will work or not.
