The Sira Eco Knit Hoody was designed with health in mind. It's made from an ultra-lightweight, eco-friendly recycled polyester that's treated with PROTX2® AV, a fabric treatment developed to decrease bacterial and viral loads. It also includes a built-in interior neck gaiter with an adjustable elastic cord lock, so you can fit the gaiter to comfortably cover your face. The breathable, moisture-wicking fabric is anti-microbial to keep it smelling fresh. It's snag-resistant and anti-pill, so it looks new even after all those washes. The women's styling has the details important for her: a slightly longer length with a shirttail hem, a crossover hood, shaped seams and tapered waist to create the perfect fit. It features UPF 15-24 sun protection, making it great for the outdoors.
