The Sea To Summit Ascent -9°C Down Long Sleeping Bag is a versatile three-season sleeping bag designed to provide lightweight warmth and adaptability for backpackers, campers and outdoor enthusiasts. Transition smoothly between the seasons with RDS-certified 750+ Ultra-Dry Goose Down, ensuring excellent insulation to keep you toasty warm when the temperature drops, complete with a hydrophobic treatment for quick-drying comfort. A technical, 3-dimensional hood provides additional cold weather coverage, preventing warmth around your head and neck from escaping and avoiding compression of the down. A panelled footbox ensures your extremities stay warm and protected. When the weather heats up, the Free-Flow Zip system allows for multiple ventilation options and the ability to open the bag flat as a quilt, enhancing its adaptability to varying temperatures. You can even fold the top third of the bag down by opening the right side half-zip, offering customisation of coverage and warmth. Its 20D recycled nylon shell features a non-PFAS DWR finish, providing moisture and weather protection in a lightweight package. Featuring a relaxed mummy fit, it offers increased comfort without compromising thermal efficiency.

  • Free-Flow Zip System: For customisable temperature regulation to enhance ventilation in warmer seasons, and versatility that allows you to lay the sleeping bag flat to function as a quilt when you prefer not to be fully cocooned
