This new Ossa Overshirt from Arc'teryx is an ultra lightweight button up overshirt that is made with a lot tougher stretch nylon UPF 50+ fabric than your average sun/windshirt that is this light in weight. Excellent durability for a lot of your outdoor needs. The fabric is slightly stretchy, highly breathable, and wind resistant. Features include textured nylon ripstop fabric that minimizes skin-sticking in hot conditions, a pop-up collar to help protect your neck from the sun, a button-up front closure with placard, and a single zippered chest pocket. Perfect for when you need a little more warmth than a t-shirt can provide, or a little extra protection from the sun and wind. This is a very new unique piece from Arc'teryx that will most likely be different from any other Arc'teryx item that you have ever owned. Hike in style and protect yourself from the sun with this new Ossa Overshirt.
