Building   on the popularity of our short-sleeve and long-sleeve astroman shirts   designed with the help of legendary Yosemite big wall climber Hans florine,   the astroman polo does it all-just without the plaid. Same stretch   nylon/spandex fabric, same quick-drying lightweight feel, same sun snap   collar, same functionality for climbing big walls (or single-pitch climbs),   hauling heavy packs, day hikes-even polo, since it is technically a polo   shirt (although our testers haven't tried that yet).
