From backpacking to our daily commute, the Mountain Hardwear Stretch Ozonic Jacket keeps us covered on our adventures in wet weather. Made with Mountain Hardwear's Dry. Q 2. 5-layer fabric, this jacket blocks out all water to keep us dry and stays breathable so we remain comfortable. Zippered underarm vents let us release our heat when we are getting too hot, and the adjustable hood and cuffs cinch up the jacket to keep out the cold wind and water. Dual hem adjusters allow us to get the perfect fit and the packable design ensures we can always have it stuffed in our bag so it is ready to use when needed.
