This fitness pants are like skinny leggings, which are great for different types of exercises. I have tried on them running and doing aerobic exercises. It really keep me warm at first and finally help me sweat a lot even in winter days. The yellow fabric of the inner side doesn’t make me any itchy and uncomfortable. It can help build the body shape but not be too tight. Next time I want to wear the pants in the sauna room. Wow! I Can’t to wait.
