3M Thinsulate Thermal Insulation Foldable Bag

This item is insulated with Thinsulate thermal insulation. Microfibers make the difference. The photos (on item tag) shows the difference between the fibers of thermal insulation and those of competitive high loft insulations. Notice the microfibers in Thinsulate insulation are ten times smaller than those of the competition. This allows Thinsulate thermal insulation to “trap” more air in less space by providing many times more fibers for insulation air to cling to the larger fibers of the competitor provides less surface area to trap air that’s why Thinsulate insulation is nearly twice as warm as all the high loft insulations and nearly and a half times as warm as down. Please see pictures for dimensions and details as they are part of the description. Top B-3
