Yep, it seems like a simple, lightweight, woven shirt, but on the South Fork of the American in the scorching heat, it quickly becomes our best friend. Lighter, softer, more breathable than ever, but still shuts out the sun and dries quickly. Holds on to water just long enough to cool us down. Drop tail hem with split back. Roll-tab sleeves. 100% poly; UPF 20. By Marmot. XS(2), S(4-6), M(8-10), L(12-14), XL(16).
