Criquet | The J.R. Shirt | NavyOur modern take on the old school chamois shirt can take you from the ranch to the boardroom. Wear it layered or rock it commando. It's the softest brushed cotton shirt you will ever own. Our shirts and jackets are a classic fit not boxy or too snug, just right. Check out our size chart above or chat with one of our customer caddies. For reference, a 511, 180 lb man would most likely wear a size medium in regular fit and size large in slim fit. 100%
