Osprey UltraLight 20 Dry Sack, One Size

I recently had to go on an international trip and I had to fit clothes good for 3 weeks inside a Deuter ACT Lite 50 +10 and still have the backpack small enough to be considered as carry on luggage with United. This dry sack was able to compress all of my clothes down into a manageable size and allowed me to carry all of my clothes with room to spare in the pack! I stuffed my clothes into this thing, sat on it to press all of the air out and then do the minimum three folds. The folding style clasp was good enough that it is able to keep the air out which maintained the "compackness" of my clothes inside. The material is REALLY light unlike the other heavy duty dry bags which I have used. I would highly recommend this product if you want to organize your backpack or to save space by compressing down clothes or if you want to keep things dry. Also, I am not sure of the exact weight but I can also see this as being used as a backpack liner to keep your gear dry instead of using a trash compactor bag which will make your pack river crossing ready.

Osprey never fails to deliver a quality product at a reasonable price. For an UL dry bag that won’t break the bank this is the way to go. So far I’ve made a point of testing mine out by overloading it, being rough with it and just TRYING to abuse it and it’s holding up perfectly. The water repellent coating is holding up well, but I suspect after prolonged and/or harder use you’d want to reinforce it a bit. I’ll definitely be picking up more of these in various sizes.

We bought it since we were going camping with some friends for the first time and they recommended it to use as a bear bag for our food. It did work great as that, but also it was fantastic as a bag for wet clothes while traveling, or to keep the contents inside of a back pack dry. We took it to HI and it was very useful for keeping our clothes dry while on boats. Truly worth it!

Not fully waterproof but good for snorkeling so long as the bag is not too full. I stayed in the water for up to 3 hours a time with the bag and only a cup or so if water leaks in, and I don't believe it was through the opening. Just roll the top at least 4-5 times and seal your phone in an extra ziplock bag. Very good quality and lightweight!

Brought several sizes of the Osprey dry bags on a cruise for our excursions and they all worked so well. Kept the wet towels and swimsuits from leaking into my backpack. Also used the 20L bag to wash these same items when I got back to my cabin. Durable, totally waterproof and ultra light weight. Cant wait to use them for camping in the fall.

I used this to replace the sleeping bag stuff sack. Stuffed my sleeping bag and all my clothes that I wanted to stay scent free in this bag while back packing. Also nice to know they would stay dry! Great item!

Bought a whole host of these for backpacking/camping. I love the various sizes and colors. They are super light weight, so far have been very durable, and don't take up much room, so I can always pack a spare one by hanging it from my backpacking pack.

Love the squared off shape, makes it easier to pack all corners of my pack. The sack is ultra light but still holds my Northface 20 degree sleeping bag and prana pillow with plenty of room to add sleeping clothes. Feels durable, but have only used it on one 2 day hike so far.
