Why We Like It

The Sea to Summit Ultra-Sil Nano Dry Sack Big River Dry bag is essentially the lightweight version of the Big River Dry Bag, meaning it's constructed with a thinner denier nylon and doesn't include lash loops. If all you want is a place to keep your important items dry and organized, than the Ultra-Sil is perfect. It comes in a range of sizes, but I've found the 8L size to be adequate for all my electronics and valuables. If you're bringing more than just a cell phone and camera, opt for the 35L.
