When we're above the treeline, vulnerable against mountain winds, we pull the Chockstone Alpine Hooded Jacket from within its own pocket and zip it on. Mountain Hardwear's Chockstone doubleweave material quiets howling winds without suffocating our microclimate. The raglan sleeves and stretch fabrication ensure we have full range of motion whether we're climbing or belaying, while the pockets remain accessible and the hood remains functional when we're clad in our harness and helmet.
