Product Description

Keeping all of your gear organised and protected is a concern whether adventuring in the Antarctic or out hiking in a balmy summer’s afternoon. We’ve designed a range of ultralight and tough drysacks specifically to help you achieve this. Made from Siliconised ripstop nylon and in a variety of eye catching colours mean that you can trust they’ll keep your kit protected and visible even in the darkest depths of your pack. It will also allow you to colour code your contents for even quicker access. We know that your equipment and organisation requires a degree of flexibility, that’s why we’ve created our drysacks in a range of sizes, from 3L to 30L. Equipped with a fully waterproof roll-top closure, coated fabric and taped seams that keep your gear dry no matter how wet your pack gets. Unlike other drysacks they have a rectangular shape. This results in more efficient packing and when removed from your backpack, they’re able to stand unaided. What’re you waiting for – make sure your gear is protected!

Double Duty: Bear Bag & Sleeping Bag Cover
Used the 20L bag on a 35 mile 3-day hike on the Appalachian Trail. When it wasn’t protecting my sleeping bag inside of my backpack during the day, it substituted as a bear bag for my food and smellables at night. The bag has a loop on both ends that can be used with paracord for securing and hoisting. Worked great!

5.0 out of 5 stars Dry, lightweight sack
Reviewed in the United States on July 22, 2019
Color: Poppy OrangeVerified Purchase
It is what it is, a good, very lightweight, and compact dry bag. I've used it to hang food when backpacking in areas that allow hanging food. It packs down super small, which is why I was so interested to begin with. Seems pretty sturdy, I've thrown it around camp on various terrain and held probably about 5-10 lbs of stuff when hanging from the tree without issues. I haven't filled it with knives and sticks, but it hasn't been pierced yet.
I have not heavily tested the waterproofing, but it has rubbed up against water containers with a lot of condensation and sat out overnight with heavy dew on it and there were no issues with dampness inside.
I don't think it will, but if this bag fails, I'd probably buy it again for the price.

Reviewed in the United States on April 11, 2016
Verified Purchase
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.

I bought this specifically for a backpacking/camping trip in Hawaii and I was so glad I brought them along. It served as a place for me to store clean, dry clothes without fear of them getting wet (while kayaking for example) and then a place for me to store dirty clothes between trips to the laundromat. I even started bringing this guy on to the airplane while island-hopping as a carry-on since the loop on the handle was easy to carry and fit under the seat no sweat. A lot easier than trying to cram it into an 85-liter pack that I was checking. A little pricey but totally worth the quality of construction and materials.

4.0 out of 5 stars Use extra ziplock for electronics, otherwise suitable for snorkeling if used properly
Reviewed in the United States on March 23, 2017
Verified Purchase
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!

Simply put I have two of these bags and they are amazing. During the summer my wife and I hike/kayak extensively and these bags keep our important gear dry. We were in Alaska hiking Reed Lakes and I fell into a river up to my shoulders. I had a $2500 dollar camera in this dry back and when I got out of the water safely the camera had remained perfectly dry. What else could you want from a dry bag?
