Outdoor Research utilizes legendary tech in their Headwall GORE-TEX 3L Pant. Designed for the harsh conditions of alpine adventures, these pants are weatherproof, durable, and comfortable while we're wearing a harness. GORE-TEX technology keeps moisture out while maintaining breathability, and fully-sealed seams double down on waterproof protection. Full-length side zippers allow easier layering, even while wearing boots, and the snap-adjustable cuffs fit comfortably over our skiing, climbing, and mountaineering footwear.
