3M™ Thinsulate™ is an extremely thin yet powerful insulation technology. It contains extra fine microfibers that trap body heat to keep the wearer warm while also allowing for a slim profiled garment with maximum range of motion and minimum bulk. Thinsulate™ also allows moisture to escape through its fibers, making it the perfect synthetic insulator for high performance sportswear.
