Why did our grandfathers wear woolen shirts even during the summer? Because wool is probably the only material that can keep us warm in winter, but is also cool and comfortable to wear in the summer. The reason is that wool is able to absorb up to 39% of its weight in moisture. That's why we do not sweat when wearing clothes made out of wool. COCO-MAT knows these unique thermal and insulation properties of wool and, after processing it with environmentally-friendly methods, uses it in the form of woolen padding in duvets, blankets, top-mattresses, mattresses and bed-mattresses.
