This is a great tank for high-energy activities. It has a nice, long length, but feels cool against the skin with its polyester/elastathane blend. There’s a hidden pocket smartly positioned on the side for a bar, gu, or other quick-access snack. And the fit looks flattering on many body types. I’m 5’3” and 135lbs and a small works well for me. A small also fits well on my 5’7” and 140lb friend due to the long torso.
