Tried sauna shorts for two weeks now. They fit snug, don’t chafe, and by the end of spinning class my shorts are soaked. It speeds up the slimming for me.

Zipping these up before a run, I can feel the heat building fast. Makes me feel lighter after my workout and they never roll down at the waist.
