This Outdoor Research compression sack solves the age-old problem of keeping your down sleeping bag dry in a rainstorm. You can leave those garbage bags at home from now on because the Hydroseal coated nylon on this stuff sack is extremely waterproof and durable. The fully taped seams and roll-top closure seals the deal, enough so that it’s submersible.
The most impressive part is the air permeable waterproof fabric that purges air during compression. An instructional video with an OR Rep shows how this innovative fabric holds water back without a leak but allows air to pass through. It’s impressive technology that allows you to compress your bag to fit into your pack and trek into the wild without fretting about the impending rain in the forecast.
