Ascent Pro 600 Down Sleeping Bag (-7C / 20F)

The Rab Ascent Pro 600 is a three-season down sleeping bag designed for multi-day trekking and camping in cold conditions, carrying a Rab sleep limit of -7°C (20°F) and an ISO EN 13537 comfort rating of -2°C (28°F) with a lower limit of -8°C (18°F). It is filled with 600g of 650-fill-power RDS-certified European duck down treated with a Nikwax fluorocarbon-free hydrophobic finish, helping it retain warmth in damp or condensation-prone environments. The outer shell is 100% polyamide with a polyurethane coating and a fluorocarbon-free DWR finish using 20D Pertex Quantum Pro ripstop fabric, while the lining is 20D recycled nylon at 38gsm. Trapezoidal boxwall baffles with a differential cut encourage full down loft and reduce cold spots. A wide mummy shape accommodates bulkier base layers, and a 3D neck collar plus a down-filled YKK three-quarter-length zip baffle limit heat loss. An angled foot box promotes a natural sleeping posture. The regular size weighs 1,190g and packs down to 40x22cm (15.7x8.7in), and left and right-hand bags can be zipped together.
