Osprey Airspeed

Osprey Airspeed
Using peripheral suspension design this lightweight, three dimensional suspension eliminates foam and backpanel materials and replaces it with lightweight suspended mesh. Three dimensionally shaped to allow maximum airflow and optimal tension and load carry sets Osprey apart from other tensioned mesh backpacks.

Osprey Peripheral Frame

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

Rated 5 out of 5 by from thru-hiked the PCT in '16. Loved this pack! my base weight was a little over 10 lbs and I used this pack (without the lid) for the northern half of a 2016 PCT thru-hike. I loved it. I was using the Exos 58 (a LOT of people used that pack happily the whole way), for the first half but other than the high Sierra, it had way more room than I needed. If I did it again, I'd take the 48 the whole way and maybe just use the lid during the high Sierra bear cannister section. A lot of people had holes develop in the mesh pockets, but if you're careful where you set it down, you'll be fine. I just washed the pack off and after 1,300 miles, it looks brand new. Definitely use a waterproof liner if you'll be in any rain.

Rated 4 out of 5 by from AT Thru-hike Took this pack on my AT Thru hike, like many other hikers. Almost half the hikers I met were carrying this pack, and for good reason. Light weight, easy to pack, quite comfortable with the trampoline back, even in hot humid weather. Could use more padding on the hip strap IMHO. Top zipper had a tendency to get stuck. Web mesh pockets couldn't stand up to Maines pine limbs that tore them up. True on the weight load, 35 lb comfortabley, and able to carry more with difficulty.

Rated 5 out of 5 by from Outstanding In contrast to the above reviewers, my EXOS 40 is generally loaded well over 30 lb: my loads average 37 lb. The extra weight is due to water: in Australia we have few water sources, so it all must be carried. I've been very happy with the ability of this pack to carry th load: after 50 km or so I get a few black bruises, but this is probably more due to my body type (featherweight) than the bag. The problem is certainly far less noticeable than any other packs I've used. Great mesh pockets that don't get caught up on scrub, excellent harness, nice and light, subdued colour for avoiding attention: all very important things to me. I think I'll stick with Osprey from now on: they make good gear.

Rated 4 out of 5 by from Professional Use I am a professional guide and outdoor educator who works all over North and South America. This pack has traveled with me for two years now, racking up nearly 200 field days of use. Here are some of my thoughts. Comfort and Fit: The pack is very comfortable. I have the medium and it fits like great. I am 5'9" and about 180lbs. It rides well just above the hips and the hip belt is comfortable with no digging in. Durability: The pack has held up really well, with the one exception of the stretchy material on the pockets. It has worn through there in a few spots, but nothing that affects the function of the pack. Uses: While this is a "lightweight" backpack, I use it on regular 30 day wilderness trips as well as lightweight trips. If you keep the weight under 35lbs it carries like a dream, anything above that and it does get a bit uncomfortable. It isn't designed for heavy weights, so don't use it for them and you will love it. That being said, there were a few times where I loaded over 50lbs in it and it carried it. Not the most comfortable, but doable. What could be fixed: 1. The hook system for the top is nice, but the flap that covers the pack with the top off gets in the way with the top on. 2. The hip pockets could be a little further forward, which is an issue I have with most Osprey Packs. Would I buy it or recommend it? Yes.

Rated 3 out of 5 by from Wider Belt Option Please! My husband has the Exos 58. I have a larger, heavier Osprey pack, wanted a lightweight for 2-4 days of backpacking. I am 5'9", about 150, with a 19.5 torso. There is not a women's equivalent to the Exo, in terms of weight especially. Really wanted the 48, but my hips are wide (as are many women!), about 37.5, and the padding ends with the buckle just where my hipbone protrudes. I wish they had extended the padding about an inch, or had an option for a larger one. Other then that, seems like a great pack, but deal breaker for me. Would only recommend this to those with skinny hips!

Rated 4 out of 5 by from Very nice pack, but fit may not be the best choice certain body types I bought this pack for my girlfriend as it was light weight while still having pretty good padding. Overall the features are great and the pack seemed really well constructed. She also really liked the blue color. Unfortunately, the shoulder straps sat a bit too far apart for her and the sternum strap would not tighten enough.,,,,Fit is VERY subjective, so take this with a grain of salt, but as always, I'd load down the pack and walk around a bit before heading off for it's first trip.

Rated 5 out of 5 by from Simply Amazing I have used this bag several times with some long mile days, loading it down with more than 25 pounds and it has performed phenomenally. It's so comfortable with that weight and every feature is just how it needs to be. The hip belts and shoulder straps are enough support, and breathe so well. The Airspeed suspension breathes well too, better than anything I've seen/used. Side mesh pockets are large and easy to use (fit an entire 1L bottle easily). Trekking pole attachment is a great feature. The Flap Jacket is great, I love not needing a large lid when you don't need it. I got the black and it looks great in person. I wouldn't put much more than 30 pounds in this bag though, not sure the shoulder straps could be comfortable with that much weight. I never want to take it off, and I plan on getting the new Atmos for longer trips.Try it on at your local store to feel it and you won't want another bag.

Rated 4 out of 5 by from Nicely been I would say that I am minimalistish. It's a great pack served me well for the last year. Has way better airflow than my Volt 65. I would also say that you want to keep the weight around 25 pounds after that it doesn't carry well I will say this my wife tried it on and said there wasn't enough padding around the hips for her.

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

- + Warranty Info

ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty

When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.

Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.

Some Osprey All Mighty Guarantee FAQs:

What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.

What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.

How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.

What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.

Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.

Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.

JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.

All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
