Details
The Spark™ Ultralight Mummy Sleeping Bag Series spans everything from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and no-frills design to provide cutting-edge performance for the designed end-use.
Ultralight does not mean ultra-tight: The Spark mummy sleeping bags are snug but still have adequate girth for the performance-oriented backcountry user.
- Superlight 7-denier and 10-denier fabrics offer minimal weight and packed size
- 850+ fill-power Premium Goose UltraDry Down™ certified to the Responsible Down Standard (RDS) and provides maximum insulation value
- Contoured mummy shape provides comfort and efficient insulation
- Vertical chest baffles prevent down migration
- Note: This bag is not designed to zip with another
