Feels great
"Very nice - soft, fits well, and feels nice and light in the heat and humidity. Not as cozy soft as the EZ tee or perhaps quite as cooling as the IcePerf tees, but I'm glad to have this in my wardrobe, too. I would definitely buy this again - it feels light and soft. I'm often between a L and XL in many brands, and the XL was a good fit for me (I prefer things on the looser side)."

Great lightweight shirt for summer running
"I live in Florida and run outside all year long. I like this shirt because it's very lightweight when wet, which is all the time in the humid summer months. It also works great under a hydration vest."

Perfect running t-shirt
"Lightweight and super soft! Love the vents on the side to help with airflow. I get super sweaty so I typically only wear sports bras to run. But this is my go to shirt when it’s a little chilly. The only comment I have is that the white stains easily. I wore this to lift and the weights left black stains on the front. 75% of them came out in the wash but they’re still faintly there if you look closely. But would recommend buying in a different color!"

Fav Trail Running Shirt for Summer 2025
"Fantastic top! I wore it for a 50k ultra race & loved it! I got the coral color. If you sweat a ton like me, you don’t have to worry about the shirt sticking to your skin! Also, super breathable & I never felt claustrophobic wearing the shirt. Like I mentioned above, I wore this shirt for a 50k ultra & even wore a hydration pack on top of it. No chafing, no issues! Highly recommend for any trail running this summer or just as a nice top to help keep you cool!"
