The Minimalist Men’s Rain Jacket is a lightweight shell featuring GORE-TEX with PACLITE Technology, making it waterproof, windproof, breathable, and extremely packable. The hydrophobic GORE-TEX membrane contains over 9 billion pores per square inch to reduce internal moisture, and the PACLITE layer regulates temperature while keeping weight to a bare minimum. The Minimalist jacket also features fully taped seams to prevent leaks, a storm flap to protect the front zipper, and an attached hood that adjusts for better facial coverage. If interior heat should begin to build up, simply open the PitZips—zippered ventilation openings under the arms—to increase air flow. Your arms will retain full mobility through it all, thanks to the built-in Angel-Wing Movement. Marmot does not recommend dry cleaning for any of it’s products. GORE-TEX fabric products, MemBrain fabric products, goose down insulated products and fleece are all machine washable. Always follow the wash & care.
