Osprey UltraLight 3 Dry Sack, One Size

I bought several of these dry sacks for a backpacking trip last year and liked them so much I'm purchasing more. They are great for not only keeping small items dry but also organising. The biggest trick is making sure you get as much air as possible out of them first. I find if I flatten them and squeeze as much air out as I can before folding the top closed they fit in my backpack much better. Once you've folded them a few times you won't be able to get any of the air trapped inside out, that's part of this whole waterproofing deal, so practice a bit and you'll get the hang of it. One of the nice things about these lighter bags is they're a bit more versatile than their heavier counterparts. I've used one of the smaller ones as a wristlet to carry my phone and camera plus a few odds and ends when it was raining just a bit and I didn't want to carry my whole pack but still didn't want to risk anything getting wet. I've also used a larger one as a mini washing machine for one or two pieces of clothes at a time, works great for socks and underwear, just put a bit of water and your travel laundry soap inside, seal it up with some air inside, and shake like crazy for a minute. Rinse out very well, add clean water, shake again, rinse again, dry. Clean laundry is yours! See, very useful! Wonder bags!

Pros: seams are sealed, rip stop fabric, solid stitching, true to size - all of these get a 5 star ratingI’m not completely aligned with calling the following as a con but...Sack will allow you to fill to the point that you will be unable to close and maintain water seal integrity. So just be mindful to leave enough room for rolling opening over to get that seal.Buckle, it’s OK, maybe even good, maybe. I don’t love it. Could be a little beefier. It is probably sufficient for the size bag, probably.This bag is awesome for keeping light jacket and other small items dry. I actually keep a 3 season waterproof jacket in mine.If you pack small and depending upon the clothing items, location/climate etc ‘‘tis possible to pack a change of clothes to keep dry. This bag is not as think as a SealLine, it is ripstop nylon with sealed seams.This bag is not a sufficient as solitary source of protection for any electronics

Purchased this dry sack to keep my electronics protected on a long-distance backpacking trip. Gets the job done perfectly - keeping everything safe and dry. The 3L size is perfect for this function and still has room to spare and would be perfect for small quantities of clothes, food, etc. The nylon material is very durable and water resistant. Color is very accurate to product description photos.Rectangular bottom shape is a nice touch compared to the more typical cylindrical bags. Bags are extremely light weight and pack down extremely small when not in use. Highly recommend these bags for their quality, style, and function.

When I first unpacked it, I thought "What no closure." Then I realized you roll top down before clipping it. Nifty idea. It holds a lot and is lightweight. Though it is not waterproof, it is water resistant. Great bag for holding all my muzzle loader ammo & gadgets.

I used this to protect my electronics on a backpacking trip. It held my camera, phone, paperwork, well... I don't plan to submerge this bag in water. When rolling the brim of the bag, then buckling/sealing the contents inside, it is necessary to purge the air. Otherwise, remaining air make this sack inefficient to pack. A good thing is that if it holds air, it will work well for the reason I purchased it--water resistance! I like the highly visible orange color that will reduce my chance of leaving leaving it behind.

I've owned and used a few of these in the past but the thing that separates this product from the rest of the dry bags, IT IS SUPER LIGHT and compact so you can even hold it in your pocket. So far no issues, leaks or breakage. Two thumbs up!

I used this to keep my sleep clothes/change of clothes dry and it worked just as it should.I was able to fit a full set of base layers (long sleeved shirt and pants) one pair of under armour underwear, an under armour short sleeved t-shirt (all size 2X) and an extra pair of wool socks.With all of this I was able to roll the bag 3 full times and it didn’t feel over stuffed or at risk of tearing.The material is very soft. The buckle is strong and secure.At the end of the day, it’s an Osprey product. You get what you pay for and I would gladly purchase this again. I have the 12 liter as a food bag and love it too!

This dry sack is used for electronics, such as a satellite communicator, that get transferred from backpack to backpack, depending on which bag is used for a particular trip. Besides the communicator, the 3L bag holds an oversized eyeglass case, headlamp, mini lantern, and a 1000 mah battery pack, with room to spare.I got it in orange to stand out so that it's not left at home or on a trip. The "poppy orange" turned out to be a bit darker than the seller's photo. The material of dry sack is translucent so that if the contents are dark the bag is darker.Also the bottom and back of the bag is dark grey material, if that matters to you. Would've gotten the fluorescent yellow if available but the orange is bright enough.
