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.
