Rab Ascent 0C / 32F Down Sleeping Bag

Size: Left Zip Regular

A versatile three-season down sleeping bag engineered for comfort and efficiency. Filled with 650FP duck down and wrapped in windproof Pertex® Quantum fabric, the Ascent delivers warmth without bulk. L.O.F.T™ construction balances insulation and weight, while sidewall baffles eliminate cold spots during side sleeping.

The wide mummy fit accommodates layering, and dual zips—including a shorter arm-access zip—add practical flexibility for camp tasks.

Hand-filled in Derbyshire to preserve down loft, it packs to just 20cm × 35cm and weighs 940g. Ideal for summer expeditions, bothies, and shoulder-season camping where weight and packability matter.

Rab Ascent 0C Features:

  • L.O.F.T™ construction uses alternating wide and narrow baffles to achieve great warmth for weight.
  • Sleep comfortably on your side thanks to the sidewall baffles, which reduce cold spots and ensure you’re not lying on a seam.
