Rab Ascent Sleeping Bag

This is a 2-season bag with a temperature rating of 25°F, making it best suited for spring and autumn conditions. While it offers excellent warmth for those shoulder seasons, it is not designed for deep winter temperatures.

The 650FP European Duck Down is treated with a hydrophobic finish, which helps the insulation resist moisture and retain its loft longer than untreated down. While this adds a layer of protection against condensation or light dampness, it is still important to keep the bag as dry as possible.

Yes, the design allows you to zip two compatible Rab Ascent bags together to create a double sleeping bag. This is a great feature for couples looking to share warmth on milder nights.

The Ascent features a spacious mummy fit, which is wider than a traditional technical mummy bag. This extra room allows you to wear additional layers inside on cooler nights without feeling overly constricted.

This construction method creates a stable, box-like shape for the down to fill, which maximizes loft and prevents the insulation from shifting. It effectively eliminates cold spots, ensuring consistent warmth throughout the bag.

The bag is equipped with a YKK anti-snag zip insert and an internal zip guard. These features are specifically designed to prevent the fabric from getting caught in the zipper track, allowing for smooth entry and exit.
