The liners of the COCOON "Silk Economy Line" are a little smaller than the standard but they are still roomy sleep sacks or sleeping bag liners for hotels, youth hostels, alpine huts, boats, planes and trains. For the "Silk Economy Line" we use the same high quality silk as for standard TravelSheets. Silk is the optimum fabric for minimizing packing size and weight. Silk is breathable, soft to your skin and responds well to changing temperatures. It keeps you cool in the tropics and toasty in the mountains. A COCOON liner adds up to 5.3°C to the temperature rating of your sleeping bag. Temperatures may vary one degree Celsius in either direction.
