LightWool Undershirt Long Mens is a long-sleeved sweater with a round neck. The garment insulates well under a midlayer on cold days or by itself on warmer days. Suitable for sweaty activities such as alpine skiing, alpine touring, cycling and running. LightWool is soft and light and especially developed for warmer days. Do you know that wool actually has a cooling effect when its warm outside? Wool insulates against heat from the outside and therefore cools on days with higher temperatures. These are garments that ventilate and regulate body temperature as per activity, made of 100% merino wool. LightWool is perfect for long tours, and wool is naturally resistant to odour. Simply dry and air the garment, and its ready to use again. Aclima LightWool is possibly the softest wool underwear you will ever try.
