CONSTRUCTION AND MATERIALS

The secret to the impressive performance is a combination of premium materials and careful design. The RDS 850+ Loft premium goose down, light-gauge #3 YKK zip and high performance 10D Nylon shell and 7D lining fabrics set the stage for superior performance. These materials are combined with a contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to best fit the use scenario.

The ULTRA-DRY Down™ protection also makes the Spark™ an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.

  • Ultralight 7D fabrics for minimal weight and packed size
  • RDS 850+ Loft Premium Goose ULTRA-DRY Down™ for maximum insulation value
  • Uses a full box baffle construction to accommodate extra down and reduce cold spots
  • Expedition mummy bag sizing provides extra space for layered clothing or extra wriggle room
  • Vertical baffles on chest optimises positions of down to prevent it moving during use
  • Full side zip with two sliders provides easy access and extra ventilation options
  • Zipper draft tube, hood and front neck draft collar to prevent warmth being lost when it’s needed
  • Shell: 100% Nylon, Lining: 100% Nylon, Primary Filling Material: GOOSE DOWN (Min. 90% Down), Stuffsack: 100% Nylon excluding Trims
