## Summary

Men's long-sleeve button-down sport shirt in a blue and sky blue check poplin fabric, featuring a classic button-down collar.

## Description

A cheery addition to your warm-weather sport shirt rotation. The collar on this one’s got a particularly nice roll to it with just the right amount of “bloom,” plus an extra button at the back of the collar, which is an old-school detail originally designed to keep your tie in place. (We just like the way it looks.) The cut is slim but never skinny, with a high armhole for mobility and a shirttail long enough to stay tucked in. (Sid likes it this way, but it's easy to shorten if you prefer.) It's made with single-needle stitching, flat-felled seams, and thick, 3.5mm Trocas shell buttons.
