Okay, so I impulse-bought this Sailwind henley after seeing it recommended in a menswear group. Wasn't expecting much but HOLY COW this shirt is comfy!
The cotton is that perfect Goldilocks thickness - not see-through thin but not heavy either. Wore it to a backyard BBQ last weekend and didn't sweat to death (major win). The three-button design gives it just enough style to look put-together with shorts or jeans.
Fit note: I'm 6'0", 190lbs and got the Large. Snug but not tight - exactly how I like my casual shirts. The arms are cut really nicely too, no weird bagginess.
Bonus points for the hidden details: reinforced stitching at stress points and an extra button sewn into the hem (why don't all clothes do this?!). Already threw it in the wash twice - hung dry both times - and zero shrinkage so far.
Downside? Now I want one in every color...my wallet isn't ready for this addiction.
