The forecast calls for fairly warm temps, but windy conditions threaten to hit once you reach the top of the trail. Luckily you have the Montane Men's Featherlite Pullover stashed in your pack so you have nothing to fear. It's made with an ultralight Pertex Quantum fabric that blocks out wind while allowing breathability so you don't overheat on steep sections of the trail. The fabric is also remarkably compressible so you can keep the jacket in your pack without sacrificing a ton of space. A DWR coating repels light rain, and elasticized cuffs and hem prevent chilly breezes from sneaking in.
