Because there’s nothing worse than wet gear. Except getting eaten by a bear—that would definitely be worse.

The Outdoor Research Durable Dry Sack is just that—burly enough to withstand the regular beatings a river trip can deliver. A roll-top closure, fully taped seams, and Hydroseal coating all come together to keep your gear dry. A webbing bottom and daisy chain make this Outdoor Research dry sack easy to grab and carry.

Dry and good for river trips or camping

  • Familiarity: I've put it through the wringer

Used this on the Green River for a 5 day float originally. Immense sand didn't ruin it. Four years later the inside rubber is fully intact and flexible. It is durable, dry, and light. I use it for camping, river trips, whatever. Keeps your clothes dry camping when there is condensation on everything.

Keeps stuff dry!

  • Familiarity: I've used it several times

I took a group of 11 people to Guatemala a few weeks ago and was looking for a dry sac to replace my old leaky one. I didn't want to lug around some huge, stiff, bulky dry sac like I've used in the past so I gave the 5L a try.

Needless to say it kept our stuff dry! I used this one to stick my wife's $3,000 camera in when the rains started falling around 2pm every day! I also really like how soft this dry sac is. One's that I've used in the past have always been really stiff and cumbersome when I'm not using them.

Very Useful

I got the 5L bag and it was great to take to the beach on a surf trip or on the boat during river trips. Kept my things dry and rolls down to compress your gear if need be.

Good buy

Excellent for keeping your stuff dry and its super lightweight. Backcountry ships fast!

Excellent Bag!

Used this bag numerous times. From going to the beach, scuba diving, or just around the pool on vacation. Each time, it's kept everything dry! The 25L bag is big enough for a couple of towels, two sets of shorts and shirts, plus numerous little things. When it's empty, it rolls down to the size of a pair of socks. Lightweight material. Overall, excellent bag!

Versatile, durable, awesome, food bag+

  • Familiarity: I've used it several times

LOVE this dry sack. Keeps all my food organized when backpacking. The durable material, webbing and D rings allow me to tie it off and hang it at night without concern. Good weight considering the features. Aside from backpacking, I have also thrown this around in the canoe with phone etc inside. The OR ultralight sacks are great for sleeping bag and clothes; but, also having one of these durable bags is great for a little more use outside of your pack.

What size (liters) do I need for a down mummy sleeping bag (women's size)? Thanks.

Responded on

Go to the sleeping bag's manufacturer page and look up the "packed size" Down vs synthetic bags for different temp ranges will all pack down to different sizes. Good Luck

Do we get paid or get a discount?

...for doing this?

I already had an OR bag in olive drab or some such that I've used for a few years now and like/trust.

What I was looking for this time was one large enough to hold my large pack inside for stream crossings, so not being sure I went ahead and ordered the largest, 55 liters, and it still wasn't big enough. Seems to be made of thicker material but I haven't taken it out in the field yet.

I'm disappointed they don't offer more subdued colors. I settled for black because at least it's not bright red or orange.

Responded on

bright colors are good for when the bag comes loose from your boat and needs to be retrieved from the river...easier to see

Very Effective, Useful Bag

Bought this bag on a whim because I had a merchandise credit from and wanted to try one of the dry bags out. I made a good choice on this one. I have only used this a couple of times so far while Stand Up Paddleboarding and going to the beach in FL. However, it's done very well for me, particularly by keeping the beach sand away from my personal items like my wallet, beach towel, etc.

Great dry bag

I use these babies for caching gear in the mountains for climbing and for lining my backpack when backpacking during bad weather. Thus far they've been indispensable, and bomber. They are tough, but not bombproof so be careful not to drag them across super sharp talus or step on them on rock terrain. Other than that they're killer bags.

So much better than Sea to Summit.

I own three of these bags. (all 15 liter) and three sea to summit dry bags, of varying sizes. Of these, I use the three OR bags religiously and will only touch my 35 liter sea to summit bag, and my compression eVent bag. The other is garbage. These bags are thick, durable and truly waterproof. I've left them outside in the rain all night to test them, and had them completely submerged. I've never had any of the contents get wet. I trust this for my down sleeping bag in the Northeast, where weather changes every ten minutes.

Which specific S2S bags are you referring to?

works great

I typically use this for a liner in my day pack when storms are a possibility. It protected my camera gear in torrential storms.

I've also used it in my luggage to protect a suit during travel (holds air really well)

Which is the brightest colored bag? I've learned to love light colored bags because you can sort through the contents of a bright colored bag easier than in a dark colored bag. Do they only offer the bag in the dark red or dark blue colors? Thanks!

Best Answer Responded on

This style also comes in black, so not a great help in that regard. Check out the Double Dry Window Dry Sacks (the window should help the sorting process) or the Ultralight dry sacks (it comes in bright orange and is fairly durable).

Responded on

The interior of every color is the same gray. I have two blue and one orange and the interior is exactly the same, so don't let the colors stop you!

I used this in Central America to keep important stuff dry as I swam across channels pretty islands of the coast of Belize. I was a little doubtful at first since it is not as sturdy feeling as some Baja bags out there, but it worked like a charm. Really easy to seal too. I am not sure how it would hold up to a bunch of abrasion yet but for keeping stuff dry it works. For more technical, and rough, activities something more durable might be better. But for stuffing in a pack, or carrying by itself it is perfect.

An innovative use of the OR Dry Sack!

I've used my back pack, the sleeves of my fleece jacket, and mittens to keep my feet warm at night, but never thought of using my dry sack....very nice..!!

Responded on

Hi Ray, I was using the 35L ones...and when it gets so cold at night..nothing beats this dry sack as a foot warmer ! Cause its fully sealed. Only problem it creates moisture inside after a while :)

Looking at the loops sewn on the side...has anyone tested their duability? I'm looking to use this as a food bag and will need to hang it. Anyone have any idea how well the loops will hold up under weight? Will be packing food for two on a three day trip.

Responded on

I think the loops should hold for you fine. I've used the loops to carry them and have clipped it onto a backpack and they have held up fine. I've never hung one but if it will hold attached to a backpack there is no reason it won't hold while hanging.

Responded on

hey johnson145,
I have used the same 15L OR dry bag to hang my food on three Appalachian Trail tru-hikes. The bottom strap works great to hang the bag.

Responded on

I have a couple of these, mostly 10L sizes but a few other ones too. I feel more than confident using the side loops for any sort of lashing. The stitching would certainly hold the weight of the contents, but it would probably fail if you took a stumble where your bag caught a branch and tore off as you fell (or something similar).

Responded on

Although the straps are very strong and secure if you want to ensure no tugging of the seams then try this. Wrap the rope around the whole bag and through the loops. This way the rope is holding the entire bag and not just the loops, but the loop keeps the rope from rolling off the bag. I have lots of these bags straps to my motorcycles this way and they hold fine at 80mph and I don't have to worry about the bags slipping.
