Very happy brotherI bought these for my brother who had your brand before but not these specifically. He loves the upgrade I bought him being a little warmer. He wanted a medium and he weighs 200 lbs. He says the fit is great and he loves these even more than the lighter weight ones.Reviewed by Estee on 1/26/2019
