The Silver Ridge can be classified as a necessity for any wardrobe. The color scheme is bold dual color blocking and the fabric is basket weave nylon. It has the unmistakable look of a dress-casual button up, but look closer and you''ll see vented back panels, UPF 50 sun pr otection, and roll-up sleeves with tab holders. So you''ll have peace of mind knowing that-while you''re at the office on Friday morning-your shirt is just as excited for the weekend as you are. Silver Ridge 100% nylon basket weave.
