The Trekmates Silk Balaclava is designed to be a liner because of silk's thermal properties, this balaclava will keep your head and neck warm without interfering with your hat or helmet. Made from 100% pure silk.
As silk is so thin you won't loose any freedom of movement, and it acts the same as a baselayer on your body. Ideal for hiking, trekking, skiing, or any expedition to high altitude where layers are essential.
