Sea to Summit Spark -9C Ultralight Down Sleeping Bag

THE SEA TO SUMMIT SPARK -9C ULTRALIGHT DOWN SLEEPING BAG

Engineered to keep you warm at the lightest weight and smallest compressed size.

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.

Ultralight does not mean ultra-tight: The Spark mummy sleeping bags are snug but still have adequate wiggle room for the performance-oriented, backcountry user.
