The soft Ultra-Sil dry sack is tough yet flexible and is designed to keep your stuff dry in the great outdoors! It is made from a special waterproof polyurethane coated Siliconized Cordura with a watertight, non-wicking Hypalon roll top and stiffener for a secure closure.

The dry sack has a slippery surface which is helpful when you’re packing your things into a tight spot like a travel bag, backpack or bike pannier. The Cordura nylon is both lightweight and waterproof which is a great combination in a dry sack. To use the bag, pack in your gear then roll down the top of the bag at least three times and buckle to ensure a tight seal. For extra peace of mind, we recommend that sensitive and/or electronic items be “double bagged” or placed inside a waterproof case inside of your Ultra-Sil dry sack.

We are able to offer the Ultra-Sil dry sack in a variety of sizes from 1L up to 35L capacity and various colours to suit your outdoor and travel needs. Choose from orange, berry, kiwi green, pacific blue, red and sky blue. The bags are highly visible, but nearly transparent which means you can see the contents without having to open and dig through what’s inside.

The Ultra-Sil dry sack collection is a must-have for anyone who spends time outside. Order one for your own use or add one to your cart for a friend or family member who loves the adventurous life!
