What Our Gearhead® Experts Are Saying:"This jacket is a game-changer for active cold-weather adventures. The Gilltek insulation keeps me warm when I'm still, but when I start moving, it vents excess heat to keep me from overheating. The lightweight ripstop fabric is durable and packable, making it my go-to midlayer for ski touring, hiking, and chilly days in town."Designed for those who never stop moving, the Morrison Gilltek Hybrid Jacket blends warmth and breathability for ultimate versatility. When we're stationary, the Gilltek insulation lays flat to trap body heat, keeping us warm during cold morning starts. As we pick up the pace, the jacket’s unique gill-like vents open to release excess heat, preventing us from overheating. Stretch side panels enhance mobility, while moisture-wicking and quick-drying fabrics ensure all-day comfort. Whether layering up for a backcountry ascent or staying cozy on a crisp fall hike, this jacket is the ultimate companion for year-round adventures.
