Threads technical enough to pack for the single-track trailhead, the Women’s Logan Short Sleeve is a sun-shielding button-up built for movement. This lightweight top starts off with an abrasion-resistant nylon Supplex & polyester weave, a blend that allows it to wick & quickly dry when damp. This shirt is constructed with an unrestricting underarm gusset & durable flat-felled seams; darts tailor a clean fit.
