Sizing and Fitting of your OSPREY pack
Fit is the key to pack performance. Take the time to get it right. If you're buying from our online store measure yourself carefully and don't hesitate to email or call customer service if you have questions. Once you have selected the pack model that meets your needs, you will need to choose the right size.
Step 1 - Pack Sizing
Most of our Opsrey packsvare available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the illustration) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).
Use the charts below for different osprey models to determine your pack and sizes.
How to pack your pack:
Be sure to use the red internal compression strap. Also, compress the contents solidly using the external compression straps. You want the pack to adopt a tall, thin profile. Remember to maintain side-to-side balance as well – a pack that leans over to one side places excessive pressure on your spine and irritates your shoulders. Make a point of getting as much gear inside the pack as possible. Odds and ends strapped on all over the outside of the pack wreak havoc with balance, especially if they are free to swing around. Finally, the top pocket has a tendency to become the repository for many, many small items that add up to significant weight and often make the pack distinctly top-heavy – be careful!
Since Osprey was founded in 1974, every single product design bearing the Osprey name has passed through the hands of owner and founder Mike Pfotenhauer, undergoing relentless scrutiny. From stitching the first lines of custom-fitted packs, to meticulously designing innovative products with intuitive features, to forging personal relationships with the sewing operators who construct the packs, Mike has been the unbreakable thread that makes Osprey a company like no other.
To celebrate its 35th anniversary in 2009, Osprey launched the All Mighty Guarantee, an enhancement of a lifetime warranty that was already one of the most robust in the industry. Free of charge, the company will repair any damage or defect in its product – whether it was purchased in 1974 or yesterday. If Osprey is unable to repair the item, it will happily replace it. The All Mighty Guarantee: any product, any reason, any era.
Osprey backpacks boast an innovative ergonomic design, ultimately designed to be comfortable and supportive.Thanks to their anti-gravity technology, the brand’s ergonomic backpacks allow all hikers to enjoy their walking adventures comfortably, without back pain or discomfort. These packs also offer incredible value for money. With the guarantee that your backpack will last for decades, if not a lifetime, you can rest assured that an Osprey purchase will be a great investment.
Great backpackBy: Fabian on 11 August 2019This is a great backpack. I have the Xenith and as it it also an Osprey, this backpack has more or less the same design and quality. I used it for my 13 year old and it fit fine. We also adjusted the pack for my 11yr old who was on the same hike so he could see what carrying a large pack was like for a while and it fit both of them really well. I would highly recommend
Ace 50 KIDS Hiking pack 50lyBy: Richelle Coundrelis on 9 November 2018Great pack for my 13 yo, he's not big enough for an adult pack but needs 50lt for his gear. Hikes a lot with scouts and loves that everything on this pack is adjustable and can be changed to suit his growing shape!
By: Simone on 12 July 2017Bought this for the kids (2 girls and a boy), after buying an Osprey hiking pack for myself. Similar design to mine which I LOVE and the easily adjustable harness means this works for all of the kids. Realistically it struggles to fit a decent sized sleeping bag in it but that's the only criticism I have. It is super comfortable for the kids which keeps the whining to a minimum, and the grown up features such as daisy chains and hipbelt pockets keeps them happy. Built in rain cover, which I still can't get in for my pack is also a nice addition. We are Ospreys newest biggest fans. Highly recommend.
Osprey kids hiking pack ACE 50By: Cass on 21 November 2016The highlight of this pack for us is the adjustable torso harness, allowing for growth of the child. The hip belt also comes with features that make it fully adjustable. The overall weight if the pack is extremely light which is another bonus to this pack.
My review of the Osprey Ace 50 kids rucksackBy: Emma Cooper on 7 April 2016This has to be by far the best rucksack on the market designed specifically for kids. I have found other manufactures say their packs are for kids but use an adult harness. The osprey pack has a harness the right size just for kids. It made such a difference to my kids enjoying hiking. Its also very lightweight which is very important for kids. My kids love the many pockets. I cant fault this pack. Really happy with my purchase.
