Keep your spirits high and your body dry throughout the most daunting alpine endeavors with the highly fortified yet lightweight Mammut Men's Meron Light Jacket. Built to keep you comfortable through the varying conditions of the mountain, this technical shell has a Gore Tex Pro three layer membrane that'll shield you from whatever precipitation is thrown at you while maintaining high breathability to prevent your body from getting too clammy. The more you sweat, the quicker the moisture escapes, while retaining the heat your body has generated. If you're still feeling a bit damp because the climb is getting the best of you, pull the underarm zip vents to get rid of excess heat. There's no question that alpinism was at the forefront of this jacket's design with two backpack and harness compatible zippered pockets as well as a horizontally and vertically adjustable, helmet compatible hood. Keep your cell phone and car keys safe and dry in the external waterproof zippered chest pocket or internal zippered pocket. The incredibly rugged construction of the Gore Tex Pro fabric will allow you to focus on your route without having to worry about the materials wearing away from heavy pack loads or close contact with rocky surfaces.
