The Merino fabric is super convenient to hiking, jogging at a walk just go with anything where you do not always want to carry around even a hat! It stays where it should be, without that (as with most towels) anything slip and down depends! By merino wool it is pleasantly warm. Taking the cloth additionally over the head, you have a warm hat to boot, which is sometimes necessary in the fall. In winter, it would be me but too cold, but I am sensitive to the effect. What I can imagine that it's also great to wear under a helmet. If this winter tried the same. The cloth is available in very many different colors and patterns! I am very happy with it !!!
