Review on Sea to Summit Ultra-SIL Compression Dry Sack, Lightweight Waterproof Bag by Brian Davis

The ultimate lightweight waterproof compression bag for hiking. I use it to carry clothes or when I'm very light in dry weather, a Mountain Hardwear Ratio sleeping bag that weighs less than 2 pounds. . It's lighter (2.6 ounces versus 4.5 ounces for the 10-liter). It has 3 compression straps compared to the normal one. 4 no ultras; The straps are also thinner and lighter. I use an eVent compression desiccant bag (white) for my 20 deg bag because it's much easier to fill without tearing outwards. Both bags are great.
