Sea to Summit Ultra-Sil Dry Sacks

April 15, 2009 by · Leave a Comment 

Sea to Summit now has Ultra-Sil Dry Sacks,  an ultra-light version of the Dry Sacks. Depending on size, they are more than 50% lighter than the popular Sea to Summit Dry Sacks.

The Ultra-Sil Dry Sacks are made of silicone treated Cordura, one of the lightest and sturdiest water-proof nylon fabrics. The seams are double stitched and sealed.

The Ultra Sil Dry Sacks are slightly transparent so you can easily see what’s inside.
Because the material is so fine, care should be taken with sharp objects.

Sea to Summit also points out that the Ultra-Sil Dry Sacks are not waterproof under water, i.e. when under pressure for some time. But for me they are the ideal supplement to a backpack inner liner (I use a garbage bag). Especially on long tours when I want a little more protection for my down sleeping bag or clothes. At this weight, you don’t need to think twice. I can get my winter sleeping bag into an 8-liter Dry Sack.
