About this product

The Rab Ascent 500 is a shoulder-season sleeping bag designed for camping and backpacking, carrying a European Norm comfort rating of 34F (1.1C) and a lower limit rating of 25F. Its wide mummy shape provides generous room to move, with a 78.7-inch length accommodating users up to 66.9 inches tall and a shoulder circumference of 61.4 inches. The shell is constructed from 30-denier recycled Pertex Quantum nylon with a DWR finish, while the lining uses 20-denier recycled nylon. Inside, 650-fill-power Nikwax hydrophobic down (17.6 oz fill weight) maintains loft even in damp conditions. A down-filled draft baffle runs along the 3/4-length zipper, and a 3D neck collar helps retain warmth at the shoulders. One internal stash pocket holds small essentials, and both a stuff sack and a storage sack are included. Packed into its 13.8 by 7.8-inch stuff sack, the bag weighs approximately 499 grams (claimed 2 lb 5 oz). A lifetime manufacturer warranty and recycled materials reflect Rab's responsible collection standards.

What people are saying

Reviewers consistently praise the Rab Ascent 500 for its durable Pertex Quantum outer, impressive feature set for the price, and Nikwax hydrophobic down treatment that maintains loft even in damp conditions. The trapezoidal baffle construction earns credit for eliminating cold spots, and the generous interior fit is frequently highlighted as a comfort advantage. Sustainability credentials, including RDS-certified down and recycled, PFC-free fabrics, are also well regarded. The most common criticisms are that the bag sits outside the ultralight category due to its weight, the three-quarter-length zipper can snag and limits ventilation on warmer nights, and some testers find the shoulder and hip area narrower than ideal. A few reviewers also consider it pricey relative to its temperature rating.
