About this product

The Rab Andes Infinium 800 is a women's expedition sleeping bag engineered for extreme cold, carrying a -23 degrees C (-10 degrees F) temperature rating. Its fill consists of 800 fill-power RDS-certified European goose down treated with a Nikwax fluorocarbon-free hydrophobic finish, delivering an outstanding warmth-to-weight ratio at a packed weight of approximately 1,358 grams. The outer shell is 100% polyamide bonded with a Gore-Tex Infinium Windstopper ePTFE membrane (45gsm) for windproof, weather-resistant protection, while the 20D nylon ripstop lining incorporates Tilt technology, a heat-reflective titanium layer that reduces heat loss by up to 32% without adding bulk. Trapezoidal boxwall baffles with a differential cut maximize down loft and minimize cold spots, and longitudinal chest and foot baffles with Flowgate technology manage down distribution. A 3D neck collar, face baffle, and three-quarter-length YKK zip with an insulated baffle seal in warmth effectively. The women's specific cut features a narrower shoulder and slightly wider hip for comfort. Packed size is 45 by 28 cm, and the bag is hand-filled in the UK. Available in Atomic colorway with a left-hand zip in regular sizing.

What people are saying

Reviewers consistently praise the Rab Andes Infinium 800 Women's sleeping bag for its exceptional warmth-to-weight ratio at extreme temperatures, with expert testers highlighting that it competes favorably against rival expedition bags in terms of packed weight and size. The Gore-Tex Infinium Windstopper shell and Nikwax-treated hydrophobic down are repeatedly called out as standout features, making this bag far more resistant to moisture and condensation than typical down bags. The TILT reflective lining and trapezoidal boxwall baffles also earn consistent praise for boosting thermal efficiency without adding bulk. The women's-specific cut, with narrower shoulders and a slightly wider hip, is noted as a thoughtful fit improvement. The most common criticism is the steep price point, which reviewers acknowledge is a significant investment, though most argue long-term durability justifies the cost. Some note the tapered mummy fit may feel snug, particularly at the foot box, for those unaccustomed to performance-oriented cuts.
