Great fit, true to size, comfortable, professional, good quality
Color: Dark Grey, Size: X-Large
I’m 6’4, 220lb with an athletic build. Great fit, good around the chest and sleeves and shirt are perfect length. Great shirt for work or a night out. Well made and comfortable! I’ll be ordering a few more colors without a doubt.

Nice shirts with inconsistent fit
Color: Light Grey, Size: X-Large
I received the black version of this as a gift which I really liked and I got a lot of compliments for it. So I purchased this light gray but it does not fit as well. It's a little tighter and a little shorter. I was hoping they all would be the same fit but apparently they are not.

This shirt brings mens dress shirts to a new level. My husband wears it with slacks or jeans.
Color: Army Green, Size: X-Large
Kudos to whoever designed and manufactured this shirt! It is stylish with interesting details. It can be gently washed in your washing machine and dried on a warm setting. The fabric is next level, feels like cotton with a tech stiffness to it. It has a dull sheen. I'd say "give it a shot". I ordered one and it was sooo handsome that I got my husband some other colors. Bonus.....The cut is generous enough to make a bit of a paunch disappear.

Well-made shirt.
Color: Light Grey, Size: Small
Material doesn’t feel light or flimsy. Very soft and fits well. Not too loose or too tight. Plan to purchase another one down the road.
