Lovely shirt. I often find it really hard to find a true slim/athletic fitting dress shirt and was cautiously optimistic about this one after comparing the measurements against shirts I have.
The fit is amazing - not billowy but not plastered on either - which really hits the sweet spot in a business context. Fabric is great, soft out of the box with that slight sheen you get with twill. I'm sure there's better out there but unless you're the type to drop two bills for some supima cotton I doubt you'll be disappointed. I'm not sure what the buttons are made of but they look and feel great. Can't speak to durability yet.
I do really wish they would offer point collared shirts rather than just varying degrees of spread. I don't wear a tie and point collars just look better in that situation.
Shipping was incredibly fast. No issues.
