Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Rated 5 out of 5 by from This fits well, and is easily adjustable. The bladder is easy to fill and clean, and the pack has just enough room for some additional supplies.

Rated 3 out of 5 by from Seems good quality, just not something I would purchase or use myself.

Rated 5 out of 5 by from This is a great little pack! I've been using it for rides on the trails right outside my town, where I don't need to bring as much as I do when riding in the National Forest. It took a little while to figure out where I wanted it to ride, though - it's more comfortable lower on my hips, but then it would catch on my saddle whenever I stopped. It's not quite as comfortable around my waist, but I've now gotten used to it and it works just fine there. Happy to have this pack!

Rated 5 out of 5 by from BSA Leader I've always liked Osprey products and was glad this new item came out. It's just the right size and does not need to be on my shoulders during the bike ride.
Date published: 2021-08-20
Rated 5 out of 5 by from Great brand Initial impression is great as I have been very happy with all other Osprey products.
Date published: 2021-08-16
Rated 5 out of 5 by from Perfect size for bike rides. Holds my keys and wallet in addition to water!
Date published: 2021-08-15
Rated 5 out of 5 by from Great little pack I used this as a little pack while out flyfishing, instead of biking, and it was great. A nice sized bladder for the packs and it held a good amount of gear for fishing.
Date published: 2021-07-27
Rated 4 out of 5 by from Nice product Was easy to adjust straps to size. The concept is nice but not sure how much it will be used when MTN biking. Bulky. Might use it for day trip backpacking.

Please note that the info provided above refers to the Torso Size / Length the pack will fit, and NOT any dimensions of the pack. Below are steps for how to measure your torso length. You should have someone help take this measurement for you so it is accurate.

HOW to MEASURE TORSO LENGTH:
1. 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.
2. Touch your chin to your chest to find the C7 vertebrae, the knobby bone at the base of your neck.
3. Make sure you keep your back as straight as possible while measuring.
4. Measure the full length from the C7 vertebrae to the iliac crest. This torso measurement determines what size Osprey pack you should carry. Refer to the size chart above to find your ideal size.
5. If you are in between sizes, it is ideal to try them both on before ordering.


HOW to MEASURE CHEST MEASUREMENT:
Measure around the fullest part of the chest.

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.
