This sack will carry our food nicely on a hike. Clasps easily and material is strong yet lightweight. Nice color.

I have the 15L and 20L and I use these dry sacks when I'm out in rainy weather. It's durable, especially for being lightweight, and easy to pack. All my gear was completely dry after spending days out in the rain, which is more than I can say for my friends who only used pack covers.

Went hunting in the Olympic National Forrest, was rained on, ever day. My gear stayed dry, though my backpack was soaked. If only OR made shells for backpacks...

Dry sacks are an essential for any backpacker, whether you’re a newbie, or an experienced trekker, and weight matters. This sack is the perfect balance of strength, packability, lightness, and dryness. I had previously stuffed clothes, and other essential items in the bottom of my pack to get smashed, but those days are over.

I bought two of these in advance of a packrafting trip. The only thing I absolutely wanted 100% dry was my sleeping bag. The 5L looked like a nice tight fit for my 35 degree down bag, unfortunately, when stuffing it in the first time, I ripped the seal right off. I was a bit more careful about how I went about stuffing my sleeping bag the second time and have managed to pack it without destroying the dry sac since. Still, I'm wary of repeating this and treat it a bit more delicately than I would like. Does it keep things dry? Thankfully, I haven't had to find out yet. It does seem a bit too fragile, even for an ultralight sac.

This lightweight dry sack is great and holds a lot of gear and keeps it really dry. I packed a weeks worth of clothes in the 35L and some other gear for a trip to Costa Rica and I had some room to spare. Keeps all your gear dry in that humid climate and when you are not needing it it packs down super small to not take up that much room. If you are looking for a great lightweight option check this one out.

These are very lightweight and due to that they are not the most durable nor are they the most waterproof. That is not the point of ultralight gear so that being said I love these for what they are. If you are looking for an ultralight dry stuff sack look no further.

The bag seemed to be airtight but not very waterproof. Used it to protect our camera bag while hiking in the rain. After a few hours of camping, we opened it up to check on our camera and the whole inside of the OR dry sack was moist. Our camera bag was moist as well. The camera did not suffer any damage, thankfully, but we lost confidence that it would keep our items dry.

I got the 2.5 litre size. I mostly put gear that I need to stay dry, in case of a downpour or leak in my pack cover. So far, it's done the job well. The clip is easy enough to handle with one hand. Also convenient size if you are at a campsite and need to bring a few things with you, but don't want to bring your entire bag/pannier.

Lighter than my other dry bags so durability is a concern but after the first river trip they seem to be up to the task.

I have both the 5L and the 20L on this and have used both of them with no leaks or anything like that. These are not the thick dry sacks that can be fully submerged in water, but are the lighter weight material, but still have fully taped seems. An added bonus is that these dry sacks float pretty well when some air is left in them when you roll it closed.

The 20 L is awesome. I love this size, I have several dry sacks. What I love about this one is that it fits perfectly into my small day bag and I can use it as a liner. It is almost the same size as my day bag and it keeps everything dry. If you want to size it down to a smaller size just roll down the top. Works great!

I got 10L and I'm super stoked on the size it came to be and I intend on using it often!

I knew we'd be backpacking in the rain. I also knew I wasn't always going to be carrying my gear as we had hired porters for our trek. So it was imperative to have a way to keep my clothes dry. We trekked. It rained (and snowed). And my clothes stayed dry thanks to this bag.

My bag is 2.5 liters. It held my one long underwear, short wool underwear, a pair of gloves, long sleeve light wool shirt and my one extra pair of wool socks. Fantastic bag for me. I backpacked from Milan to Sarche Italy in rain and wet brush for 116 miles over a week long period. It kept my clothes dry. What more could I ask. Light/compact/dry : Quality. Now get this bag, smile and have a fantastic time :)

None of my gear got wet on a recent rainy sailing trip. This is the sort of gear that you should always have on hand. When you need it, it's priceless. highly recommend for any outdoor gear arsenal.

I really like the bag compared to the sea-to-summit ultra sil bags. This feels better made, the top closure is a smoother material that will seal better, and the polyester is more slippery then the Sea-to-Summit making stuffing a sleeping bag easier. OR also has a fantastic warranty. None of these ultra light bags are ever totally waterproof, but I will update this review again once I get it in the rain. I don't anticipate any issues. The 10L weighed in at 1.4oz.

I've used this bag a few times and it has held up well. I left it on the ground in a downpour and everything inside stayed completely dry. The bag is very light, so the exterior isn't as robust as a that of a heavier bag would be, but that's a sacrifice you make since this one is lightweight and not expensive. Great product. UPDATE The bag is tougher than expected. On my last trip, I accidentally left a metal fork in the bottom and piled stuff in on top of it in preparation for a bear hang. Even though the prongs pressed hard against the bag overnight, it didn't tear. Not saying you should try it, but it may be good to know.

Over the years I seem to have accumulated a number of down garments stuffed in their own sack pocket or stuff sack.Keeping all these pieces together can get to be chore.An ultralight dry sack is the perfect ticket.

Outdoor Research makes awesome dry bags and dry sacks. The stitching and seams are great. This particular model is lightweight and won't take a ton of abuse being tossed and drug. If you need a more durable bag or sack that will see the outside of your bags etc, get one of the non-ultralight sacks or even the "durable" dry bag or sac. I use this for ensuring my down bag stays dry in case of emergency.
