Here's what Neat fans have to say...

“My new go-to shirt!”

“This shirt kept me looking dry and fit perfectly! Hot and humid weather is here and I sweat super easy. It was a nice change of pace to wear this shirt and not look like I just ran a marathon...not that I run a lot of marathons lol! This shirt is perfect for any occasion and I will most certainly be adding more colors to the wardrobe.”

Matt P., Verified Buyer

“It's Like You Gave My Shirt Superpowers”

“In one day, the green Neat shirt stopped the rain when I was outside and then they had me looking 100% dry after 6 hours at an all day festival in 90 degree heat. I will be stocking up on more once you all get more blacks in stock.”

Jim H., Verified Buyer

“These shirts relieve my anxiety”

“I work in the film industry and always sweat when I work. I’ve always been so self conscious of it, sweating through my shirts - I would often bring an extra shirt to switch into. With these shirts, whatever magic they put in there, I can go all day, I’m still sweating, but not having to worry about the way I look.”
