I purchased these last year. Both are men's size S, but they fit like a slightly loose M. They can be worn in spring, autumn, and summer with the sleeves rolled up, so they can be used in a wide range of seasons. This is a set of two shirts, navy and beige, which are easy to incorporate into your wardrobe. The following is a quote from the official website: The classic and popular Bahama Long Sleeve Shirt, which is a symbol of PFG. It has a soft, cotton-like texture and is dry and quick-drying. The "Omni-Shade Broad Spectrum" sun protection function protects the skin from UV-A and UV-B rays, and the ventilation function on the back enhances breathability, comfortably supporting fishing in the sweaty summer. The sleeves have loops for rolling up, which helps with temperature adjustment and sun protection. The chest has a distinctive classic design and a trendy, relaxed international fit, making it a popular item for fishing, summer outdoor activities such as camping, and everyday wear.
