Marmot Men's Aegis Jacket The adjustable hood can be rolled into the collar for a streamlined fit. Water-wicking DriClime fabric lines the cuffs and collar of the Jacket, pulling moisture away from the skin for unbeatable dryness even during especially heart-pounding pursuits. Water rolls right off of the Jacket due to its built-in MemBrain Strata technology. PitZips allow you to control how much air gets in or goes out, making it a cinch to stay as warm or as cool as you'd like to be. 100% seam taped to provide optimal waterproof capabilities.
