The O'Neill Men's Mutant Jacket is what happens when a street savvy style gains snowboard worthy protection. It has a waterproof breathable HyperDry membrane with critical seams taped to prevent snow from seeping through places that most likely let wetness in. 3M Thinsulate insulation in O'Neill's Firewall body mapped design gives you more warmth where you need it. The Mutant also features zippers under each arm for ventilated airflow, and the protective powder skirt zips off in order to transition into winter casual without a problem. There's a jacket to pant interface that connects to O'Neill ski pants for complete coverage. Hand gaiters keep snow out of the sleeves, and yes, there are thumbholes. O'Neill configured this jacket with pockets specifically designed for phones, goggles, and media players.
