What if UV sun protection was built directly into the fabric so it that it would never wear off? That’s exactly what the folks at Sun Precautions figured when they designed this Women’s Full Zip Workout top. Fortunately, they didn’t just rely on building in 100+ SPF sun protection. This top also includes a hidden zipper pocket, a full zipper front, cooling underarm and back panel for ventilation and a great fit. In the future, don’t be surprised if this sort of built-in sun protection becomes common in all sorts of outdoor gear.
