The Mentor Jacket has been ruggedly designed, tested, and built for ultimate storm-worthy protection in remote, big-mountain environments. GORE-TEX Pro Shell fabric offers bomber abrasion resistance and a helmet compatible hood fits securely to keep the cold out. Engineered for motion, an alpine cut minimizes bulk allowing the jacket to move with you. With fully taped seams and water-resistant zippers, this alpine jacket keeps the weather on the outside. TorsoFlo hem-to-bicep side zips provide ample ventilation when the climbing gets steep and sweaty.
