Why We Like The Sea to Summit Big River Dry Bag
Whether we're floating down a small stream, navigating open seas, or blasting big rapids, we trust the Sea To Summit Big River Dry Bag to keep our goods dry. Rugged, abrasion-resistant nylon stands up to just about any surface, and the TPU laminate sheds water to keep our extra clothes, food, sleeping bag, and other gear dry. With the bag's 10K waterproofing rating, all we need to do is roll down the top, stash it or lash it, and spend the rest of the time enjoying the adventure.

Big River Dry bags
[This review was collected as part of a promotion.] We love our Big River Dry bags. We have several bags and in different sizes. We have been using the 65L for years for storing gear on our car racks keeping them dry and clean. The river bags are very strong and durable and the lash points are perfect for tying them down. We recently bought the 20L bag along with a sling strap to carry our 10L water cell to some of our hike to camp sites. This did a great job to stabilize it as we cradle it in front of our body to help distribute the weight. Another great resource for us. Thank you Sea to Summit in making excellent products.

Travel with confidence
[This review was collected as part of a promotion.] I purchased the Big River dry bag and am very pleased with quality material. I especially like the reinforced side loops for securing the bag. Previously I purchased your good quality water proof dry bags that are slippery.

Love these bags!
[This review was collected as part of a promotion.] I bought a few different sizes to use for my bikepacking set up, I appreciate the multiple lashing points, it makes it much easier to strap onto my bike. Have used them for a few rides and so far they’ve held up wonderfully. I also used them during a split boarding yurt tour to strap some stuff on outside of my touring pack and they kept contents dry. In that case, also appreciated the multiple lashing points.

Bomber!
[This review was collected as part of a promotion.] I absolutely love these bags. They're bomber, not light weight (comparatively), but bomber. Overall great layout, strong straps, and ready to get thrashed (mine have seen more than a few rock scrapings). Everything stays dry!

Dry and Secure
[This review was collected as part of a promotion.] The bag met all of our expectations. Its primary purpose is to protect a digital camera system when we are on adventures in wet conditions or areas. It is doing that function wonderfully. Could not be happier with this product. Thanks!

Quality gear
[This review was collected as part of a promotion.] I mostly use these bags for motorcycle camping - it’s kept my gear dry during literal down pours. Love these and will probably be buying more sizes.
