Royal Robbins 3/4-Sleeve Passport Shirt - Women's - 06 The Passport is loaded with every possible convenience. The 95% nylon fabric combines durability with high performance, but still has a pleasantly soft feel. Flexibility and shape retention are provided by the addition of elastane fibers (5%). In addition to taking hardly any space in a pack, this strong 4-oz fabric dries fast for sink washes, has DWR Teflon® stain resistance from DuPont® and provides UPF 40+ protection for your skin. A zip secure front pocket is placed on the seam so it won't clutter the look, while a full zip front makes this a truly useful shirt or light jacket. Tabs on the sleeves keep them decisively in place when you roll them up. So named because once you have one, it will be almost unthinkable to travel without it.
