This is the new base layer proposed by CMF. You can wear just this one piece as a base layer when climbing mountains, camping, or playing outside. The impression from the field test was that it is warm when standing still, and the wind can escape just by walking. It is made entirely of OCTA, the latest fabric that combines sweat absorption, quick drying, ultra-lightweight, and heat-shielding/insulating properties. Packable. Reversible. As an aside, Teijin Frontier said that this is the first time they have delivered to a Japanese brand.
