The Mountain Hardwear Men's Plasmonic Jacket keeps you completely dry and cool through sopping wet downpours and high humidity levels. The secret to the Plasmonic's boosted breathability lies within its Dry. Q EVAP membrane, which spreads built up perspiration across a larger surface area for rapid sweat dispersal and drying. Ultimately, this interior surface wicking technology works to keep you dry and cool, even when you're trekking through heavy rainstorms and sub tropical dewpoints. Other protection savvy features include a water repellent AquaGuard Vislon zipper, an adjustable hood for deployable storm protection, as well as hook and loop cuffs.
