The Big Agnes Yarmony is a lightweight, warm, and ultra-comfy synthetic insulated jacket. This jacket is insulated with Pinneco Core, which is designed to be more breathable, thermally efficient and sustain ably engineered than other insulation options. The fit is relaxed, with a flattering quilted design which allows for layering underneath. All the while providing excellent range of motion whether you're pedaling home on a cool night or ripping turns before work.
