The Button Up Shirt has a straight, classic fit that is neither too tight nor oversized. This menswear-inspired style features an exposed center front placket and straight finished hems. The shirt has full-length sleeves that can be worn rolled up or down for added sun protection. It is made using the Riviera Weave, Claudent’s answer to the perfect summer fabric. With cotton or linen shirts, 2 out of every 3 harmful UV rays reach your skin. Claudent pieces protect you from over 98% of UVA/UVB rays.
