Super comfortable and excellent breathability. Perfect for long days on the court. Small slits under the armpit are great to keep you cool. I’m a big fan.

Flowstate* Zip Tee

The medium fits him perfectly, and most mediums do, so it runs true to size. The fabric is fantastic. He can wear it to work and then wear it to Pickleball afterwards.

Thrilled with this shirt. Comfortable and stylish. Fits true to size. Will be ordering more.

I've enjoyed the zip neck shirts from another company for years and when I saw Stack introduce them, I had to try one out. These shirts are very comfortable and the zipper neck allows just the right amount of ventilation. I highly recommend this product. I am 6'3", about 205 lbs and I wear a size large.
