For decades I have sought light weight merino wool tops and bottoms as it is just the best material for a base layer. Polyesters smell bad after half a day wear and do not feel comfortable.Silk is not as good as merino wool for comfort and merino breathes better and dries faster than silk. The only problem I have with these is I bought a 2XL because of prior experience with merino shrinkage. The label says "MS" and I am not sure why- Misses size? I am 6 foot and weigh 170 and they fit perfectly and did not shrink with warm wash and warm dry cycles.
