Recommended for Bodypump, Bodyattack, Bodycombat, and Bodyjam studio classes. It feels a bit smaller than a standard M size. I haven't worn it much because the size didn't fit. It has a unique design and color, so it's recommended for those who don't want to wear the same thing as others in the studio. First come, first served. It's also recommended for men, but personally, I recommend it for women for layering, etc. Please refrain from purchasing if you are looking for a perfect item or are very sensitive, as it is stored at home. Non-smoking home, non-smoker.
