Cumulus x Gossamer Gear Aerial 330 Sleeping Bag

  • Trusted Partners

    For over 35 years, Cumulus® has been manufacturing high-performance, ultralight gear in Poland using exceptional locally sourced down. The Polish down is the gold standard—thanks to decades of expert care, ideal climate conditions, and cutting-edge science. No synthetic fill has managed to out-fluff, out-warm, or outlast the real thing.

  • Ultralight Fabrics

    Known for being tough, ultra-light, and performance-ready, Toray Airtastic® takes the crown as the lightest downproof fabric on the planet at just 19g/m².

  • Traceable Down

    Cumulus sources its down exclusively from certified Polish producers, ensuring the down comes from free-range geese with access to water and ethical treatment that contributes to the quality of every feather.

Gear Notes

Meet the sleeping bag that does more with less: a limited-edition Cumulus Aerial 330. Weighing just 17 oz and rated for 30°F, it ditches the extra down on the bottom (your sleeping pad’s got that covered) and skips the zipper for max performance. Designed with 900 FP down and sleek Toray Airtastic® fabric, it’s a minimalist’s dream for outdoor adventures. 

Features

  • Single air sealing layer of fabric in the bottom of the sleeping bag
  • Close-fitting mummy shape with no zipper
  • Differential cut design
  • Trapezoid chamber construction
  • 3D-shaped hood with two different drawcords for easy adjustment in the dark
  • Advanced footbox construction for better protection
  • Independently filled top and bottom sections
  • Simple mattress attachment system
  • Stuff sack and storage sack included
