Unisex beanie perfect for work and sport activity, manufactured with 3M patent thermal insulating material. 3M Theinsulate special microfibers are about 10 times smaller than other synthetic insulating fibers, i.e. they are much more efficient in holding air and more effective in keeping the body warm. This system allows to have much more fibers in the same space, where they reflect most of body heat. Ideal thermal insulation: it guarantees high performance with low thickness (less than 60gr). Synthetic insulation helps staying warm and dry capturing and keeping body heat, while allowing moisture to come out. It's made of elastomeric fibers 40% stretching in all directions to move with the body. More freedom of movement and maximum comfort.
