These versatile and highly breathable GORE-TEX pants are suitable for a wide range of mountain activities. Movement in nature is accompanied by change. Changes in terrain, temperature, and weather. Wind brings rain, which eventually turns to snow. The versatile Beta Pants are designed to handle a wide range of conditions, environments, and activities. The durable waterproof and windproof GORE-TEX material uses GORE(r) C-KNIT backer technology for enhanced comfort and breathability. Full side zippers make them easy to put on and take off. The regular fit with articulated patterning enhances freedom of movement. Updated with an improved fit. I purchased these as a replacement while my other pants were being repaired, but I never wore them, so I am selling them. Tags have been removed, so they are being offered at a bargain price. Purchased from the Arcteryx online store.
