Sea To Summit | Spark 3 Ultralight Down Sleeping Bag 18ºF
ENGINEREED 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.
