Created as part of Columbia's Performance Fishing Gear range, the PFG Uncharted II Long Sleeve is a lightweight technical tee that works for anglers, hikers, runners and pretty much anyone else moving about outside over summer. That Omni-Wick™ fabric helps to wick away sweat and keep things cool, while those covert thumbholes in the cuffs give a bit of extra arm coverage when the sun goes in.
