Additional Information

The Spark is an ultra light bag with several key uses. Its balance of size, weight and warmth make it excellent as a summer sleeping bag, especially for weight and space conscious cycle tourers and ultra light walkers. Its size and warmth rating works well as a liner bag, slipping inside another sleeping bag to add one or two seasons to its rating.

The secret to the Spark’s warmth to weight are in the premium quality down and high performance microweight shell and liner fabrics, the 1/3 length light-gauge #3 YKK zip and the sewn-through transverse baffle construction.

The Spark compresses so small, Sea to Summit had to re-engineer their compression-sacks to make one that reduced sufficiently. The ULTRA-DRY Down™ protection makes the Spark an impressive hard-alpine or adventure racing sleeping bag, where down has never before been a viable option, and weight is simply not tolerated.

1/3 Zip Mummy Bag
The Spark is cut as a close-fitting mummy bag. The full hood, foot box and short zip maximise fit and warmth while keeping weight and bulk to a minimum.
