The Prism Belay Jacket is engineered to provide critical warmth and protection during prolonged periods of inactivity on exposed ridges or ledges. Climashield Apex insulation delivers reliable thermal efficiency and retains loft even after repeated compressions, ensuring performance through repeated packing and deployment. Composite body mapping enhances functionality by placing dual layers of insulation in the torso for superior core warmth, while single layers in the hood, lower arms, and underarms reduce bulk and improve mobility, allowing for free arm movement during technical tasks. The 15-denier nylon shell is treated with an additional coating developed to enhance water resistance, achieving a 1000mm hydrostatic head rating. This advanced treatment sheds snow and light moisture effectively, ensuring the jacket performs in stormy, high-altitude conditions. Designed to layer over alpine gear, the Prism Belay Jacket is an essential piece for climbers needing dependable insulation in extreme environments.
