About the Rab Alpine -12C/10F Long

What is the Rab Alpine -12C/10F Lightweight Down Sleeping Bag good for?

Built for all-season use, the Rab Alpine -12C balances ultralight materials with 650 fill power down insulation to deliver practical comfort with a packable design and first-class warmth-to-weight performance for technical mountaineers and committed winter adventurers who demand reliable cold-weather protection.

A tapered mummy shape optimises comfort while minimising pack size, making this bag ideal for alpine adventures in colder conditions. Innovative L.O.F.T 3D baffle technology uses alternating wide and narrow baffles for optimised heat retention and reduced bulk for streamlined mountain travel. Sidewall baffle construction helps reduce cold spots while a drawcord-adjustable, anatomical hood ensures a secure fit for maximum thermal efficiency during cold mountain nights. The sleeping bag also features an anatomically shaped footbox that creates a relaxed sleeping posture with a 3D insulated neck collar contouring around your shoulders to seal in body heat and prevent cold drafts from entering. Additionally, the 2-way YKK 3/4 length main zip with insulated baffle provides versatile temperature control whilst maintaining high-loft insulation behind the zipper.

This product unleashes Rab's technical mastery in high-altitude equipment design, ensuring every component tackles real-world alpine challenges with proven results. Additionally, RDS certified down provides environmental responsibility whilst delivering relentless thermal performance without compromising ethical standards. The slim-fitting tapered design optimises warmth-to-weight performance whilst reducing unnecessary material that adds bulk. Furthermore, construction using 20D Pertex Quantum nylon ripstop ensures durability for sustained mountain use. Hand-filled in the UK, all Rab sleeping bags benefit from never having had their down compressed before use to preserve loft and warmth.
