The B400 consists of 400grs 3M thinsulate. 3M Thinsulate insulation ensures that it stays comfortably warm. The sides and waist of this undersuit are made of stretch fleece, so you have a lot of freedom of movement. The B400 is a slim-fit model, which means that the suit fits nicely. The undersuits are designed and made in our own factory in Europe. This allows us to have the undersuits made to measure or to meet other requirements.
