Thinsulate insulation works by trapping air molecules between you and the outside. The more air a material traps in a given space, the greater its insulating value. Because the microfibers in Thinsulate insulation are far finer than other fibers, they trap more air in less space, which naturally makes it a better insulator. Thinsulate is breathable, moisture resistant, machine washable and dry cleanable.
