M BETA JACKET Connecting with mountain nature happens different ways – backpacking big terrain, hiking through a sea of trees, powering up a peak to take in the view. The Beta’s versatility frees you to explore your way. Durably waterproof and windproof, its GORE-TEX fabric with GORE C-KNIT backer technology is quiet, soft, and engineered for enhanced breathability. A streamlined hood quickly adjusts with a single pull, and the trim fit accommodates light layers and is patterned for mobility and freedom.
