The Bamboo Shade Long Sleeve II is the second generation of this womens style, now with an updated and super dialed fit. Same indulgently soft and stretchy fabric. Same impressive 50+ UPF rating. Naturally odor-resistant, its perfectly suited for travel or an active lifestyle. Its also temperature-regulating, so itll keep you that just-right temp when the forecast (or the airplane A.C.) throws you for a loop. The weight of the fabric has a really nice, flattering drape to it, and youll probably start to wonder why all clothes cant just be made from this stuff.
