Extraordinary warmth for minimal weight, the Mythic Ultra Down Jacket features a Pertex® Quantum shell. 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-to-weight ratio. It combines advanced heat-retaining TILT technology with the lightest, strongest fabrics and the unrivalled warmth-per-weight of goose down. We also use a combination of baffles to maximise performance. Lightweight stitch baffles on the arms and hood provide improved mobility, and box baffles around the core encourage the down to fully loft, maximizing heat capture. The baffles are offset, which distributes the down evenly around the core and reduces the chance of cold spots.

Positioning 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, providing comfortable warmth on icy belays and frozen summits. To keep weight to a minimum, we used an ultralight 10D shell that's 100% recycled. This ripstop-infused Pertex® Quantum fabric is strong, durable, weather-resistant and feels soft to the touch.

Designed for climbers 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 sack are designed to be lightweight and low-bulk.
