Rated 5 out of 5 by from Waterproof is dustproof too I like this primarily because its non sticky material (rip-stop) on the outside which makes it easy to fit into other bags and easy to pull out. I keep equipment in them packed down with soft wraps for protection. all of the other dry bags Ive seen which are made of urethane or have a plastic or rubber finish dont work cause they tend to stick to each other especially in warm weather. Also these one have a nice set of loops on the sides for added fastening. Because its ripstop fabric theres less likelihood that these will split. Ive used mine in very dusty environments too and they perform very well.

Rated 5 out of 5 by from Best! I've tried Seal Line, Sea to Summit Lightweight, and another (i forget). These 'big river', in any size, are easily the best. The material is quite tough, but not overly heavy, and not the heavier "oil skin" style of Seal Line bags, which, IMO, don't hold up to folding or scrunching. By comparison, I don't care for Sea to Summit Lightweight bags -- mine have snagged something in the kayak and torn.

Rated 5 out of 5 by from Tough and dry! Awesome lightweight material. A dry bag that won't wear out. InItIally bought my first one to put food, phone and snacks in for short paddling trips. Now i have a few and use them for clothing storage in my Camping backpack also. They are easy modular bags that can throw around. I love the strap attachments (a feature that the others seem to leave out). Grab one and never have to worry about durability, weight, water tightness or how you can secure it down.

Rated 3 out of 5 by from Read the Details Make sure you read the details about this product (unlike me). It comes in assorted colors, and you can't pick the one you want. I thought it would be blue based on the photo, oops. Now I have a blaze orange bag I have to return. Any hunters out there need an orange waterproof bag?

I would like to use the Sea to Summit Big River dry bag as an waterproof ice bag on our sailboat. Would we be able to use the ice, or would chemicals in the bag leach into the ice?

Asked by: clarkchild
We do not recommend transporting ice for drinking inside of the Big River Dry Bag.
