Product Information
Full details
The Rab Ascent Down Sleeping Bag -6°C is designed for mountain explorers needing reliable warmth and comfort in cooler conditions, offering insulation down to -6°C. Its key benefit lies in its excellent warmth-to-weight ratio thanks to 650FP duck down and L.O.F.T baffle construction, ensuring durability and packability for multiday trips. A potential caveat is its specialized mummy shape, which may feel restrictive for some users accustomed to wider sleeping bags.

FAQs
What is the temperature rating for this sleeping bag?
The Rab Ascent Down Sleeping Bag has a 'Limit of Comfort' rating of -6°C (21°F). This is the lowest temperature at which a user in a curled position is generally comfortable. The 'Comfort' rating is 0°C (32°F) and the 'Extreme' rating is -24°C (-11°F).
How do I wash my down sleeping bag?
It is recommended to hand wash or machine wash on a gentle cycle using a down-specific cleaner. Rinse thoroughly. Tumble dry on a very low heat setting with dryer balls to help restore loft. Do not use fabric softener or bleach.
What is the difference between the Comfort and Limit ratings?
The 'Comfort' rating is the temperature at which a standard woman can sleep comfortably. The 'Limit of Comfort' rating is the lowest temperature at which a standard man can sleep for 8 hours in a relaxed position. Individual experiences may vary based on metabolism and personal cold tolerance.
Can I use this bag in wet conditions?
The bag features a DWR finish on the outer shell for water and wind resistance. The down also has a hydrophobic finish. While it offers some protection against light moisture, it is not designed for prolonged exposure to heavy rain or very wet environments. Proper care and drying are essential.
What are the included accessories?
The bag comes with a drawcord stuff sack for compression during transport and a separate zipped storage sack with a water-resistant base for longer-term storage and protection.
What is the packed size of the sleeping bag?
The packed size is approximately 20cm x 35cm (7.9in x 13.8in).
Is this bag suitable for side sleepers?
Yes, the bag features a wider mummy shape and sidewall baffles designed to reduce cold spots and allow for more comfortable side sleeping positions compared to a traditional mummy bag.
Troubleshooting
Bag feels cold or less warm than expected.
Ensure the hood is fully cinched and the collar is snug. Check that the main zipper is fully closed. Verify that the sleeping pad used is providing adequate ground insulation. Allow the bag to fully loft before use. Consider wearing additional base layers or socks if temperatures are near the bag's limit.
Zipper is difficult to close or snags.
Ensure no fabric is caught in the zipper teeth. Use the anti-snag insert and pull the fabric taut as you zip. If the zipper is stiff, a small amount of lubrication (like graphite from a pencil lead) on the teeth can help.
Down appears clumpy after washing or storage.
This is normal for down. Gently tumble dry the bag on a very low heat setting with dryer balls. This process helps to break up the clumps and restore the down's full loft and insulating properties.
Bag smells musty.
The bag needs to be aired out or cleaned. Store in a dry, well-ventilated area. If the odor persists, follow the cleaning instructions carefully, ensuring the bag is completely dry before storing.
Pros and Cons
Pros
- Excellent warmth-to-weight ratio for its temperature rating.
- Durable and wind/water-resistant outer shell.
- Comfortable fit with a roomy footbox and features for side sleepers.
- High-quality down insulation with hydrophobic treatment.
- Packable design suitable for multi-day expeditions.
Cons
- The mummy shape might feel restrictive for those who prefer more space.
- Requires careful packing to achieve its minimal packed size.
- Down insulation is less effective when wet, despite the hydrophobic treatment.
- The -6°C limit is a 'limit of comfort' and may be too cold for some individuals in true cold conditions.
Setup, Compatibility & Care
Setup: The Rab Ascent Down Sleeping Bag is ready to use out of the box. Unpack it from its storage sack and allow it to loft naturally. For best loft and warmth, give it a gentle shake before getting in. Ensure the YKK zip is fully open before entering the bag.
Compatibility: This sleeping bag is designed for use with sleeping pads for added insulation from the ground. It is compatible with standard sleeping mats. The wide mummy fit accommodates additional clothing layers for colder nights.
Care:
- Storage: Store the sleeping bag uncompressed in the provided breathable storage sack when not in use. Avoid storing it in its compression stuff sack long-term, as this can damage the down's loft.
- Cleaning: Hand wash or machine wash on a gentle cycle using a down-specific cleaner. Do not use fabric softeners or bleach. Rinse thoroughly and tumble dry on a very low heat setting with clean tennis balls or dryer balls to help break up clumps of down and restore loft. Air dry completely before storing.
- Maintenance: Periodically check the YKK zip for smooth operation and clean any debris. The DWR finish on the outer fabric may need refreshing over time using a suitable product.
