COCOON Thermolite Silkweight combines the advantages of silk (30%) and Thermolite (70%) in a unique new ripstop fabric developed by COCOON. It is even more lightweight and fast drying than pure Thermolite.
Thermolite provides warmth and comfort at the lightest weight, even when wet. Its hollow-core fibers trap air for better insulation. Thermolite dries 20% faster than other insulating fabrics and 50% faster than cotton. It wicks moisture away from the skin to the surface of the fabric where it can evaporate more quickly. Extremely lightweight, warm and fast drying sleep sack or sleeping bag liner for hotels, youth hostels, alpine huts, boats, planes and trains.
