Warm, enveloping and comfortable, wool is the most known animal fiber and has been used by man for centuries. KOHRO has decided to only use Merino wool unrivaled in terms of quality and delicate consistency. This selected raw material provides multiple advantages: excellent thermal insulation, absorbing and wicking moisture up to 33% of its weight, it does not irritate the skin or crease easily, it is anti-static and light, and it neutralizes odors. Merino wool uses natural resources, regrows periodically and only needs water, fresh air, sun and grass. It is also completely biodegradable.
