Product Description Item No.   10270424

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.

FEATURES of the Osprey Ultralight Dry Sack

  • Rectangular shape
  • Roll top closure

OSPREY MEASUREMENT GUIDE

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.

HOW TO MEASURE TORSO LENGTH:
• 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.

HOW TO MEASURE HIPBELT SIZE:
• 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.

Rated 5 out of 5 by from Product is good, MooseJaw - Fantastic I bought this as a gift for my daughter to contain a camping "rope kit". There is room for this kit, an extra 100ft of 555 cord, because you never know when parachute cord will save your life or make camp more comfortable. There's room for other survival items too. Compress it and it fits nicely in her kit. Blue is her favorite color and this blue is the perfect shade - true blue... MooseJaw is fun to deal with, their brand of humor, knowledgeable reps, rapid delivery and on some parcels "sealed with a kiss" sticker make me smile big. I recommend this small compression bag and especially MooseJaw to anyone.

Rated 4 out of 5 by from Very Light Weight. Wide Mouth. I purchased the Osprey 3L Dry Sack since I have 2.5L from Seal Line and it is a long and narrow cylinder, but fits a water bottle nicely. I like the wide mouth of the Osprey, but the light weight material is very thin -- basically one layer of silnylon. The Seal Line bag is a much thicker material and water sealed better. However, for my use, the Osprey works great! I put my rolled-up Patagonia down vest inside, quickly and easily, and it's just the right size (I'm a Medium). I carry the bag in the inside pocket of the vest when not in use. It's very light weight.

Rated 5 out of 5 by from Great Light Weight Sacks Bought the 3L after already having a using the 6L and 12L sizes. These bags are great light weight bags for camping or other travel. I normally use the 12L for clothes, the 6L for food etc., and the 3L for toiletries while camping. I have not used them in super wet conditions yet so can't really comment to how well they work against water.

Rated 4 out of 5 by from Works as Expected Bought this awhile back and am satisfied. I have brought it on a few kayaking adventures and is great to keep keys, phone, wallet, extra clothes, etc. dry, even if/when it fell into the water. Sometimes it's a bit hard to efficiently pack everything in (oftentimes lots of air gets in there) but that's just a user thing, not necessarily the product). Haven't tried to leave it in the water yet, but I'm sure it would be reliable.

Rated 5 out of 5 by from I have been a huge fan of Osprey products for years because of their durability and superior workmanship. This stuff sack does not disappoint. I bought it to use during climbing and plane trips to facilitate packing small items or things I want to keep separate from the rest of my pack. Great for snacks and toiletries, grab bag to keep in the car for workout stuff, just about anything. Replaces ziploc bags.

Rated 5 out of 5 by from good sac... always wanted to say that! everything in my pack is in dry sacs. this one is keeping freeze dried food stuff to hang in a tree to keep away from big critters... Yep, it's pretty lightweight. like the extra loop on the bottom so im not suspending by the clip alone.

Rated 5 out of 5 by from Best Dry Sack Out There Light, durable and waterproof, what else do you want? I've used this bag on countless backpacking and kayaking trips, it has never failed me. It, so light and packable, there really is no reason not to use it with anything that you do.

Rated 4 out of 5 by from Roomie Very nice quality, I am pleased with the usability of this bag, just wish there had been a better description of the sizes. Maybe show what can fit in them. I could have used a size down. but still happy I bought it!

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!

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 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!
