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.
Some premium details on this button down include button-less cuffs and innovative under-collar buttons to keep the collar neat. They are tailored to fit shorter men perfectly, thanks to a shorter overall length. Like all of our shirts, these have a modern fit that is gently hugs the arms but gives plenty of room in the chest and stomach.

Love the fit. I'm 5' 2" and weigh 120lbs and I'm in good shape with natural muscle mass and this shirt fits perfectly. It affirms my gender identity and the quality of the shirt is amazing. Stretchy, nice cut, and breathable. I'm diggin" it and I will definitely will be picking up some more. Would love to see an army green. Thank again under 510! I've been struggling to find a true masculine pro outerwear. And you made my dream come true. Peace!

I’m 5’6” and fairly muscular. I’m stuck between a small size that looks too tight or a medium size that fits ok upper half, but looks like a blouse in the lower half.
I love this shirt because the medium is the perfect length in the lower half. The stretchiness is also great in showing off what I got, but not making it look like I went out of the way to wear something tight.
If you are questioning which size to order, I would order up. Just DON’T CUT OFF THE TAGs! Or you can’t return it. Luckily, it fit perfectly for me.
