I have bought the midweight tops & bottoms the past two years and thought I'd try the Heavy weight bottom. I really love them and from now on the heavy weight is what I'll buy. They are not super thick and stiff. You can move around and work out doors as I do just fine. I think these are a little stronger made and I ruff on cloths, so these fit the bill for me. I don't know that I could say they wick water as well as the adds say, but other then that they are really great.
