We've worn this gear beneath our riding suits in temperatures ranging from 50 to 100 degrees. It is very comfortable and is very effective at wicking moisture from the body. Although like all things BMW, it is a bit expensive. But you get what you pay for.
The fit is snug. But the material is very stretchy and does not make you feel like you're in something too small.
The fit is pretty normal. I normally wear a large tee shirt or golf shirt and the large size fit me well, although is was snug by design.
This new version is more attractive than the older "grey" version. But they are both very functional. I guess that's why they call it "functional" underwear.
