Our dry sacks are made out of 1.0 oz dyneema composite fabric. All the seams are sealed with dyneema tape giving a complete seal to the inside and outside of the bag. We have also used our Omni tape at the top of the bag making it easy to open and close. You will be able to conveniently roll the top of the bag down and close it with a quick release buckle.
