Inspired from heli missions and cat trip adventures, the Mountain Hardwear Boundary Ridge GTX 3L Jacket is the ultimate in weather protection and durability when you are facing exposed terrain on the line of your dreams. The durable polyester shell is ultra-tough against rugged terrain, and 3-layer recycled Gore-Tex protects you from the wettest conditions imaginable while still allowing your body to breathe and regulate temperature. Underarm zippers allow airflow when you're headed across the ridgeline to your drop zone or bootpacking up a couloir, and oversized drop pockets fit an extra pair of gloves, your climbing skins, or a radio for backcountry use.
