A lightweight 150gsm Merino wool blend helps you manage your temperature and wick the sweat away from your skin when you're out on the trails.

Every great adventure starts from a solid basecamp. At 150gsm, the lightest TERREX Merino Base Layer in the range uses a blend of 60% merino and 40% Tencel which keeps you comfortable all the way up the trails, and all the way back to base.
