The sun might be shining but warm weather hunting conditions bring challenges all their own. The Early Season 3/4 Zip Shirt is purpose-designed with long, hot late summer/early fall days in mind. The lightweight polyester fabric is durable and features 50 UPF sun protection to guard your skin against damaging solar rays. Human scent is always a concern, so Silvadur technology has been added to provide long-lasting odor control. The 3/4 length zipper and strategically-placed mesh panels on the back and underarms maximize ventilation to keep you cool. Flatlock stitching reduces chafing. The tall collar helps keep the sun and backpack or sling straps off your neck
