Fit Note
Designed with a comfortable regular fit for effortless everyday wear. The short-sleeve shirt offers a relaxed silhouette, while the coordinating shorts feature an elastic waistband for a secure yet flexible fit. We recommend ordering your normal US men's size. If you prefer a looser, more oversized fit or are between sizes, consider sizing up.
Measurements shown are for the finished garments laid flat. The shorts feature an elastic waistband designed to stretch for additional comfort. Actual garment measurements may vary by up to approximately 1.2 inches (3 cm) due to the manufacturing process.
