The Rab Ascent Down Sleeping Bag (-6°C) is designed for comfort-focused mountain and backcountry use, delivering reliable warmth and practicality without unnecessary weight or bulk. It’s built for regular outdoor adventures where a balance of comfort, packability, and thermal efficiency matters most.
Filled with 650 fill power European duck down, the Ascent uses a well-designed baffle construction to maximise warmth while keeping weight low. Its wide mummy shape provides extra room compared to more technical alpine bags, making it especially comfortable for trekking, backpacking, and multi-day trips.
A windproof Pertex® Quantum outer fabric helps retain heat by reducing cold air penetration while maintaining a lightweight feel. Each bag is hand-filled in the UK, ensuring the down has never been pre-compressed, which preserves loft and long-term insulation performance. Durable and versatile, this sleeping bag is a dependable choice for cool alpine conditions and regular mountain use.
