Using the warmth of 850+ loft 90/10 goose down, the amazing moisture protection of ULTRA-DRY Down™, and a micro-weight 10D Pertex® shell and 15D lining, we have created one of the best warmth for weight minimalist sleeping bags available. 

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 concious 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 secrets of 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, we had to re-engineer our compression-sacks to make one that reduced sufficiently.
