First off, Shane was fantastic, I wanted to swap for a larger rash guard and he had that in the mail the same day.
When I got the rash guard it was much more durable than I expected, some rash guards feel very thin and as though they would rip after a few uses. This rash guard feels very sturdy and like it will for sure last for quite some time.
I will for sure be making more purchases from Gray Beard Grappling.
Thanks for the great customer service as well as the great product.

Love my rash guards. I like the sticky stuff at the bottom that helps it stay in place
