Men's Prologue Insulated Jacket

Tested against the unpredictable shifts of Colorado’s high-altitude weather, the Prologue Insulated Jacket is built for the in-between moments that matter—brisk mornings at the trailhead, chilly airport transfers, or that quiet transition from race-ready to recovery mode. It’s a performance-driven layer designed for comfort off the bike, with technical features refined by the demands of riders who live in ever-changing conditions. The jacket features 37.5® Technology in both the shell and lining to regulate temperature and manage moisture in real time, keeping you warm when you’re still and breathable when you’re in motion. Lightweight and packable, it includes active insulation that adapts to your output—trapping warmth without overheating. With a low-noise construction and a clean, modern silhouette, the Prologue Insulated Jacket is the piece you’ll reach for when comfort and capability both count.
