Great Purchase

It has provided me with peace of mind knowing all of my things are well contained and I have never been afraid of anything getting wet.

Nice Dry Bag Material

Not sure how it will work in freezing temperatures.

Not Waterproof After 3 Years Of Use

These are good durable bags, but I noticed that my clothing was damp coming out of the bag. After the 2-week trip I filled two of the bags half full of water and watched a steady drip of water coming off the bottom. It seems that the bottom seams are not watertight. I carefully examined the seams and along the 360-degree run, and about 20% of it had a gap. Apparently, the bottom 'weld' had not sealed all the way around, hence the leak. 2 bags, 2 leaks, damp clothes.

35l Dry Bag

Did everything I needed it to. Fit all of my camping gear inside and kept it nice and dry. Bag was easy to secure to the motorcycle. Always a plus.

Love The Big River Dry

Love the Big River Dry Bag for bikepacking. This last purchase augmented my collection of various sizes of this bag. This bag stands up to the hard use I give it. I would probably choose a lighter design for backpacking, but for cycling, this is the one.

Best Dry Bag On The Market!

I can't say enough about this dry bag and the company that sells it. It's my number 1 travel bag for motorcycle camping and backpacking. It's like a bag out of Harry Potter with nearly infinite space. The Sea to Summit crew is absolutely amazing and I will always come back to this company. Incredible gear and incredible people!

Excellent Drift Boat Bag

I’ve got 2 of these that I use for emergency gear in my drift boat. Works great! Solid construction and a steal at the price.

Great Durable Dry Bag

Bought the 20L and 13L for a rear relentless rack on my bike. 20 was a little big 13L for a little better. Looks and feels very durable. Love the sewn in straps on this version as well.

Dry-ish Bag With Great Tie-down Points

I brought several of the Big River dry bags into the Grand Canyon on a twenty-five day winter rafting trip. These bags kept my stuff dry-ish. The main seam running the length of each bag was not fully sealed and allowed air out and water in. Additionally, the bag material allows for water to wick into the bag at the roll closure no matter how careful and diligent I was to roll it perfectly flat. The tie-down points are amazing though.

Excellent

Man, I love these bags. Fork bags. Laundry bags. Trunk bags. Super solid. I love the built-in lash points. Favorite dry bag for adventure travel & happy to use for general travel, too.

Airtight, Tough

Bought this to use as a bearbag for hiking. It's tough, airtight, not super heavy, haven't had anything get wet inside.

Works So Well For Bike Packing!

Using this both to attach directly to the fork and just as a general bag for bike packing, and it’s great it is totally bombproof through dust and mud

High Quality Dry Bag

I bought the dry bag to use for miscellaneous stuff on the back of my motorcycle. It's high quality and good looking, holds everything I need it to with room to spare. The texture helps keep it from sliding around and keeps compression straps secure. Would 100% buy again.

Seriously Quality Dry Bag

Over nearly three decades of sea kayaking I have used a lot of dry bags�and these are certainly among the best. I particularly appreciate their shape: The flat sides keep them from rolling around and make them easier to pack. They also tend to fit my boat better.
