We produced this Tube to support the POW, Protect Our Winters, organisation. 1/3 of what You invest here goes directly to POW. Come on now let's be part of the force and make a change! Tuben 140 g/m2 warm 50% Merino 50% Recycled Polyester. Made in Europe. Our light merino, smooth to your face and neck. No smelling, no itching, keeps you in a great temperature comfort zone at most outdoor conditions. Merino won't ice up either even though breathing through it.
