Designed for the harshest alpine conditions, the Alpha SV Jacket provides rugged protection. Super durable N100d GORE-TEX PRO delivers highly abrasion resistant water and wind proofing, without compromising breathability. As the clouds roll in, a helmet compatible Storm Hood ensures full coverage and visibility. Regular fit for easy layering, the articulated cut and no-lift gusseted underarms allow unrestricted mobility. For comfort and safety, Cohaesive hem adjusters function as Hemlock , preventing the jacket slipping when wearing a harness. Pit zips aid with ventilation and all zipper pulls are easy to operate with gloves for on-the-go adjustments. With a RECCO reflector to help emergency search and rescue, this hardwearing jacket leaves nothing to chance when facing high altitude challenges.
