Overview

Meet Rab’s Ascent Down Sleeping Bag in Ink, designed to blend lightweight performance with reliable warmth. Built for camp nights that range from brisk days to dew-wet mornings, this bag emphasizes comfort without sacrificing packability. It uses ethically sourced down and a thoughtfully chosen shell to balance warmth, weight, and durability—perfect for car camping, backpacking, or hut trips.

Key Benefits at a Glance

• 650-fill European duck down certified to the Responsible Down Standard (RDS) for peace of mind and dependable warmth in exposed conditions.
• A recycled Pertex Quantum shell keeps the bag airy and compressible, so it easily fits in a backpack or duffel when you’re on the move.
• The Ascent line favors a bit more space for sleeping positions, while staying lighter than many alpine-focused bags.
• An internal zippered pocket keeps essentials like a phone or small energy items within easy reach.
• Regular size weighs about 2 lb 13.5 oz with a packed size around 15.7" x 8.6", offering a balance of warmth and portability.

Materials and Construction

The bag is built with a lightweight yet weather-resistant shell, designed to handle a range of conditions. The recycled Pertex Quantum fabric provides a protective layer that is both durable and packable, while keeping overall weight down. The interior layout includes a left-side zipper for easy entry and a secure pocket for small items, so you can stay organized on the trail.

Temperature and Use Scenarios

The Rab Sleep Limit for this version is -9°C (16°F), making it suitable for cool evenings at high elevations or damp climates when paired with appropriate layering. It’s equally comfortable for car camping setups, hut trips, or overnight backpacking where space and weight matter. The regular cut offers room to shift positions, which many campers appreciate after a long day outdoors.
