The poplin weave of these shirts is casually lightweight for suppleness and ease of wear. Made from 100% cotton, the 2-ply 100s yarn is considered a 'superfine' material that's crafted with maximum comfort in mind. We've used a split-back yoke so the shirt rests easily on your neck and shoulders. And, with sizes ranging from S-XXXL, you can even size up or down to achieve the optimal fit.
