The Alpine Jacket in our Mythic series is designed for those moving fast and light. For those who want an extremely warm down jacket you can climb in, stash easily, and throw on when you need an instant boost of heat. Shaving grams wherever possible it has lightweight, low bulk, stitch-through construction to stabilise the down while allowing excellent breathability. Squares around the core maximise warmth while regular baffles on the sleeves improve mobility. Pre curved and articulated the sleeves have also been designed to allow easy arm lift, movement, and articulation for climbing.To keep weight at a minimum we used an ultralight 10D outer which is 100% recycled. This Pertex® Quantum fabric with built-in ripstop is strong, durable, weather protective and feels soft to the touch. Slim-fitting and low bulk, the jacket layers easily under a shell and helps manage moisture through your gear, perfect for moving at pace. When a balance of weight, mobility and warmth are critical for success, the Mythic Alpine Jacket is the ultimate choice.Details Fit: Slim Insulation: 900FP European Goose Down with Nikwax Fluorocarbon-Free Hydrophobic Finish (140g / 4.9oz, Size M) Centre back length: (Size M): 75cm / 29.5inch Weight: 313g/11oz (Size M) Lightweight zoned stitch-through construction for optimum warmth and down stabilisation Down-filled hood with part elasticated opening and stiffened peak Lightweight YKK® VISLON® centre front zip with fleece lined chin guard for comfort Precurved and articulated sleeves for improved fit and movement 2 YKK® concealed zipped hand pockets Part elasticated cuffs for optimum fit and reduced bulk Dual sided rear hem adjustment with anti snag tether Supplied with a lightweight stuff sack Outer: 100% Recycled Polyamide.
