The Osprey Ultralight Dry Sack is waterproof gear storage for your sleeping bag, clothing, and whatever else you need to keep dry on the trail. The 40D nylon ripstop fabric is durable, yet ultralight, with waterproof coating throughout as well as coated seams. The roll-top closure secures it closed with a clip. Conveniently shaped like a rectangle so you can align your backpack Tetris-style. Too bad Osprey doesn't make an L-shaped one.

Rated 5 out of 5 by from Nice and lightweight I bought this a month ago and have yet to use it in the field, but it is the perfect size for a point and shoot camera, a journal, and other small necessities. Looking forward to testing it out soon for durability.

Rated 5 out of 5 by from Gets the job done I bought this bag and used it on a canoe/backpacking trip in Canada and it worked perfect. The sack is light and keeps everything dry. I have a 12L and a 24L. I use the 12L for my sleeping bag and have never had problems with it!

Rated 5 out of 5 by from Lightweight Bought for small storage during kayaking trips. Folds up really small when not in use and is easily compressible. Small size is perfect for a sweater and lunch.

Rated 5 out of 5 by from Exactly as described! I received this as a Christmas gift and can't wait to use it. The dimensions are perfect and it's exactly as described. I plan to use it to keep my phone/wallet/etc. extra safe while on boats/scuba diving.

Rated 5 out of 5 by from Nice! Purchased to use as a bear bag for several multi day trips. Very lighweight, yet seems extemely sturdy. The clasp is good and tight and I like that it has the loop you can use to hang.

 What size would be best for carrying a Compressible lightweight down sweater or vest

Asked by: Azrider
Hiya Azrider, thanks for your question! A very compressible jacket and vest should fit in a size small (6 liter) sack. Hope this helps!

What are the care instructions for this product? Can it be washed? Rinsed only? dried?

Asked by: dhco
Hey there, Thanks for reaching out to us! If there's one thing I love....it's dry sack questions. So, with Osprey dry sacks, you're going to be absolutely fine with putting these in the washing machine. Settings won't matter. However, once the washing cycle is done, avoid the dryer. Just to be safe, you're going to want to air dry this bad boy. Hope this helps you out!

Does this come with a strap to wear crossbody or backpack style?

Asked by: Molly
Hey there, Thanks for the awesome question. Unfortunately this item does not come with crossbody or backpack straps. What you see on the product page is all that will come with the item. There is a small loop to attach it to a backpack but no straps to be worn as a backpack. I hope this helps!

what size would fit a standard sleeping bag?

Asked by: Irene
Thanks for the question! The size will of course depend on the size of your sleeping bag. The most common dry sack sizes are 12-15 liters. Hope this helps a little!

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.
