Patagonia Men’s Long Sleeve Bluffside Shirt. After the overnight train ride from Prague to Budapest, your travel-tested Bluffside Shirt still looks fresh. You, however, might need another cup of coffee. Soft and comfortable on the skin, the Bluffside has a 100% organic cotton garment-washed twill fabric that stays cool in the heat, washes in the hostel sink and withstands long journeys whether you’re traveling by rail or by foot. Softly textured with a button-down collar and clean-finish stitch detailing throughout, it features a passport-compatible left-chest patch pocket, a subtle, slim-fitting profile and traditional shirttail hem.
