The Ultra Sil Compression Sack is a lightweight waterproof drysac ideal for squeezing your gear into its smallest possible form whilst protecting it from geting wet. Made from 30D Ultra Sil fabric it has excellent strength as well as a 2,000mm waterhead.
The base is made from eVent breathable waterproof fabric to allow air to escape the bag when compressing but without letting water in. The seams are double stitched and have been reinforced on stress points as well as being fully taped, plus the Hypalon roll top closure is secure and does not wick moisture, so you won't have any leaks.

Customer Reviews of Sea To Summit Ultra Sil Compression Dry Sack
I bought this sack to compress a marmot phase 20 sleeping bag to half the size of the compression bag that came with the sleeping bag. I was not disappointed.
