The Florence RIFFE DIGI-TEK© Sun Pro Long Sleeve Hooded UPF Shirt features a 50 UPF rating, moisture-wicking fabric to keep you cool and a 4-way stretch knit construction. We grab this shirt for long days on the boat or whenever we're going to be out in hot, harsh elements for extended periods. For this style, we replaced the gaiter with a crossover hood for more low key sun & wind protection.
