This tank it perfect to take to the gym or trail! I have used it a few times in the gym and love how lightweight and breathable it is. It will be my go-to tank this summer while out on the trail. The fit is perfect, loose so you can move in it, but not too much where you are swimming in it. My only call out is that the collar is tighter around the neck than I expected, especially since the rest of the top is loose. Other than that this tank is perfect!
