Product Description

All Spark sleeping bags are characterised by their ultra-light weight, minimal packing size and excellent thermal performance. The SpI's quilted construction minimizes weight and the vertical chambers in the chest area optimize down distribution and prevent slippage. The zipper on one side makes it easy to get in without unnecessary weight. Optimized sizes offer more space on the shoulders.

Ultra Dry Down
UltraDry Down is a PFC-free water-repellant treatment applied to the down used in all Sea to Summit sleeping bags. UltraDry Down retains over 60 % more loft, absorbs 30 % less moisture and dries out 60 % faster when compared to untreated down – which means the down will insulate better even in damp conditions. The treatment also inhibits bacterial growth, making your bag last longer. UltraDry Down treatment is an environmentally friendly application.


  • Ultralight 7D and 10D material for minimum weight and packing size
  • RDS-certified 850+ Loft Premium Goose Down with Ultra-Dry
  • Down treatment for maximum insulation values
  • Contoured mummy shape guarantees efficient insulation
  • Vertical breast chambers protect against cold bridges
  • Note: Cannot be zipped together with other sleeping bags
