Extraordinary warmth for minimal weight, the Mythic Ultra Down Jacket features Pertex® Quantum outer fabric. Combining TILT technology with 900FP down and baffle construction, it's our warmest lightweight down jacket to date, the product of extensive R+D.

Alpine down jacket with the best warmth/weight ratio. It combines advanced TILT heat-retaining technology with the lightest, strongest fabrics, and the unmatched warmth by weight of goose down. We also use a combination of baffles to maximize performance. Lightweight stitch baffles on the arms and hood provide better mobility, and box baffles around the core encourage the boom to be fully lifted, maximizing heat capture. The baffles are offset, which distributes the down evenly around the core and reduces the chance of cold spots.

Placing the TILT layer as close to the body as possible maximized heat retention. This heat-reflecting layer gives the Mythic Ultra Jacket a noticeable increase in thermal efficiency, pleasant warmth in icy gatherings and icy summits. To keep weight to a minimum, we use an ultra-lightweight 10D exterior that is 100% recycled. This Pertex® Quantum fabric with built-in ripstop is strong, durable, weather-protective, and feels soft to the touch.

Designed for mountaineers and mountaineers, it has a helmet-compatible hood, two-way front zipper for use with a harness, and fine articulation through the sleeves for climbing. All zippers, adjusters and stuff bag have been designed to be lightweight and low in bulk.
