The Cube down jacket is built for cold-weather versatility, combining a 10D matte micro ripstop nylon shell with a durable water-repellent finish to keep moisture at bay. Filled with 650 fill power real down (90/10 grey down), it delivers reliable warmth and heat retention while keeping bulk to a minimum. Elasticated cuffs and hem create a close, ergonomic fit that seals in warmth and allows freedom of movement across a range of outdoor activities.
