Rab Ascent Sleeping Bag

Yes, with a 0°F temperature rating and 650FP European duck down insulation, it is built specifically for cold-weather trekking. The L.O.F.T™ construction optimizes heat retention, making it a reliable choice for freezing conditions.

The Ascent is designed with sidewall baffles and a wide mummy shape, which provides significantly more room than a traditional, restrictive mummy bag. It is specifically engineered to accommodate side sleeping positions comfortably.

The secondary zip is a versatile feature that allows you to stick your arms out for reading or cooking while still inside the bag. It also provides extra ventilation if you start to overheat without needing to unzip the main entry.

The packed size is 10.2 inches by 17.7 inches. While it offers excellent warmth, it is a substantial bag, so you should ensure your pack has enough volume to accommodate it alongside your other gear.

The maximum user height for this bag is 73 inches, which is exactly 6 feet, 1 inch. If you are right at that height, you will fit, but you may find it snug if you prefer extra room at the foot box.

The shell is made from 20D Pertex® Quantum nylon ripstop, which is designed to be both windproof and durable. It balances lightweight performance with the toughness needed for mountain adventures.
