Insect repellent and sweat don't mix, which is why we've baked a powerful bug blocker right into this tricked-out half-zip. Our Insect Blocker technology keeps bugs at bay without requiring sprays, lotions and other potions that end up everywhere when intensity rises and sweat comes into play. But this multi-tasking top does more than bust bugs, it also repels harmful UV rays with UPF 50 sun protection. The contoured collar offers extra coverage for the back of your neck and sleeves are cut longer to protect hands. Use the extra-long front zip to customize your ventilation. FEATURES: Fabric: 100% polyester Bug SHield Double Knit, Insect Blocker, Omni-Shade UPF 50 sun protection, 4-way comfort stretch, Contoured collar, Center back length: 26", Imported,
