From the beginning of my teaching career, I've had to deal with sweaty armpits. I've tried everything...sweat pads, prescription deodorants, none of it worked. A friend of mine suggested the Thompson Tee...It's a miracle!

High School Teacher

I [was] diagnosed with hyperhidrosis when I was 20. I've never had something that soaks up sweat like this, that doesn't show underneath and that's so comfortable.

Joe D.

Corporate Sales Operator

I was so excited when I bought my first set of Thompson Tees I bought each one of my three siblings some because we all suffer from the same problem. They love the tees and so do I and I'm still buying them two years later.
