Merino mix

Very pleased ,this is my third purchase of different levels ,great prices fast shipping

Base layer to rule them all!

Super comfortable, odor resistant, 1/2 zip makes it very adaptable to activity. I just happened to see this at a random store and hadn’t heard of Terramar previously. Now I’m buying more to replace the others I have.
