Our Flex collection of polo and button down shirts were made for the man on the move. The fabric is made from a cotton blend jersey knit that feels incredibly soft against the skin. It also stretches in every direction making these shirts absurdly comfortable and effortlessly practical.
Like all of our polo shirts, these have a modern fit that is gently hugs the arms but gives plenty of room in the chest and stomach. Some premium details include a curved hem and innovative undercollar buttons to keep the collar neat. They are tailored to fit shorter men perfectly, thanks to a shorter overall length.

I'm 5'7" and the Mediam was too short in torso length which was unfortunate. Whenever I raise my arms, 40% of my torso shows and I have to pull it back down once I drop my arms. I'm super surprised that I am too tall for something.
The good things are that the material feels nice and smooth and the arm length was perfect.
Sadly, I will be donating mine to someone else who can maybe fit it better.

Flex Polo Black
Rated 5 out of 5 stars
Great fit and comfort
Just what I've been looking for in a Polo shirt. Sleeves aren't long and baggy, and I don't feel like I'm wearing a skirt. The curved hem adds a distinctive touch. Price is well worth it to have casual shirts that fit like they were made for me.

Flex Polo Black
Rated 4 out of 5 stars
Fabric Great! Fit Great! Length... Less great
I love the way that the polo looks and feels! Under 5'10 has upped their game year after year. One thing with the polos that has been the only thing about the polos has been the length. They are right on the cusp of too short. I feel like I need just a half in more in length to really feel 100 in them. The scoop hem was exactly what needed to happen to the polo though! That has made the difference.

Flex Button Down Shirt Black
Rated 5 out of 5 stars
perfect for casual or formal
Fits perfect, great quality. It is slightly thicker than the typical dress shirt fabric so if you're in miami or somewhere hot perhaps not. But the stretch and quality is great. I dress casual primarily so these can be tucked in or left tucked out which i really like. U510 is my go to brand so i'll get more of these
