    Great workout shirt

    I do lots of stairmaster for warmups and am soaked after 30 min. Leaving the rest of my workout wet and messy. I tried this shirt and it def keeps you dry-er than the cotton shirts I normally wear. Works great.

    perfect workout shirt

    I can wear this 3-4 times if needed between washes. Just make sure you can air it out if you sweat a bunch. I've worn dozens of times and washed a bunch. Looks brand new
