Rab Ascent Down Sleeping Bag Ink – 16°F, Regular, Right Zip

Overview

Meet the Rab Ascent Down Sleeping Bag Ink edition, a versatile choice for camp nights that blends lightness, warmth, and practical features. It uses ethically sourced 650 fill European duck down and a recycled Pertex Quantum shell to create a bag that feels nimble in the pack yet generous on the inside. The design is roomier than more alpine bags, helping you find a comfortable sleeping position after a day of hiking or scrambling. An internal zip pocket keeps essentials within reach, so you can unclutter your campsite and wind down with your device or small items close at hand.

Key benefits you might notice

In this version the insulation and fabric choices work together to deliver dependable comfort in a range of conditions. The Rab Sleep Limit of 16F (-9C) is a useful guide for cool evenings around the campfire, hut trips, or shoulder-season bivouacs. The 650 fill down is ethically sourced and RDS certified, offering down warmth without excessive bulk. The shell fabric is recycled Pertex Quantum, lightweight, compact, and properties designed to resist light moisture and wind, helping you stay comfortable without feeling overheated when the night warms up or you move around in your sleep.

• Down For Anything helps the bag stay lightweight and durable while maintaining warmth.
• Temperature rating provides a target for planning, not a guarantee in every night’s weather.
• Ethically sourced down supports responsible supply chains and animal welfare standards.
• Pertex Quantum shell keeps the bag sleek and packable while offering weather resistance.

Beyond warmth, this bag emphasizes practical living on quick trips. The Regular cut is roomier than tighter alpine bags, which can be preferable if you shift positions at night or share a tent. The internal zippered pocket is a small but meaningful feature for keeping your phone, headlamp, or small batteries accessible and safe without digging through your pack.

• Roomier fit helps you move naturally while sleeping.
• Internal pocket offers easy access to essentials.
• Lightweight shell and compact packed size support efficient trekking, car camping, or hut adventures.
