Looking for a sleeping bag that prioritises warmth, comfort, and practicality? That will give you an easy night’s rest in the wild, without compromising on weight or pack size? This robust, reliable down-filled bag offers the versatility you need for regular mountain use. Armed with 650FP duck down, a spacious wide mummy shape, windproof Pertex® Quantum fabric, and a clever baffle construction that maximises warmth for weight, it's perfect for trekking and backpacking adventures.

Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, preserving its loft and warmth.

  • 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.
  • A second shorter zip with integrated snap closure allows you to use your arms while retaining heat in your sleeping bag, ideal for cooking in the cold.
  • Cinch in the hood to seal in the heat, while the synthetic insulated collar sits snugly around your neck.
  • Sleep in a relaxed, comfortable position thanks to the roomy, anatomically shaped foot box.
  • Keep valuables and essentials close at hand with a zipped internal stash pocket.
  • Wide mummy fit gives space for extra layers when night temperatures plummet.
  • Internal cordlocks positioned below your collar bone for greater side sleeping comfort.
  • Two-way YKK® ¾ length main zip with synthetic-filled baffle.
  • YKK® anti-snag zip insert and anti-snag internal zip guard.
