Sea to Summit Big River Dry Bag, Heavy-Duty Dry Storage, 20 Liter, Jet Black

Rugged bag that keeps things inside dry.

Bag works great - I use it to carry/store my workout clothes in my office but I've also taken it on some kayak trips. Zero leaks. It completely contains the smell, moisture, etc. While it's been very durable - after a year I had a small issue come up. I sent them a warranty claim just out of curiosity - they shipped me a new one immediately, no questions asked. Fantastic company - I'll probably order a larger one soon. They've got my business for life.

Purchased this bag after researching all the brands on Amazon as it was the sizes I was looking for and thought these were reasonable price. We took these to the Galapagos Islands and Antarctica to carry our camera gear on the zodiac boats from the main ship to the island landings. It was really a blessing. One person on our Galapagos trip had a big wave hit their zodiac boat and drenched them and their camera equipment. Everyone tried to help dry out her equipment, but it didn't work the rest of the trip. Highly recommend this bag, it has been tested. Just follow the folding up instructions!

I recently used a 20L HD Big River (HD - or you can save a little weight with the non-HD Big River which lacks a reinforced bottom and lash points).I lashed this to my rear Tailfin rack with a couple straps for a super slim and fast-packing setup. On top of this I layered a hydration pack and reflective vest which I prefer not to wear. The 20L size was perfect for what I carried. It was slim enough to not get in the way of my legs and not too long for the small-ish rack space on my small framed gravel race bike.But it was super hot for this trip (June/July 2024, central NC to the Coast and back. With temps in the mid-to-high 90°s) I slept in hotels and did not use the packed Big Agnes UL2 tent/fly, poles/stakes, footprint, sleep pad, etc. - which took up most of the space. Even with this bloated shelter/sleep setup I was able to fit in my change of kit (jersey, bib, socks- also not used as I cleaned it nightly in hotels) and off-bike clothes (underwear, shorts, thin long sleeve, short sleeve) as well as toiletries.So lesson learned. On trips where I'm not camping I'd use the 13L or smaller and carry a slimmed down emergency bivy/blanket setup.

High quality bag, robust materials. Time will tell!

I purchased this to protect a expensive 12v blanket I use in my camper. This bag is super strong and very high quality. The fabric is nice and the color is gorgeous. Pricey but I won't need to replace this bag for a long, long time.

I like that it does well for my purposes. It has kept my extra clothing dry through several rainstorms!I havn't used it long enough for an entirely thorough evaluation but, so far, it seems good.

I ordered this in 5, 8, and 13 liters and the two that have arrived so far are both functional/durable awesomeness. After some years tolerating other brands these are well worth the money imo.
