Spark SP2 Sleeping Bag
Spark SP2 Sleeping Bag is a very good quality sleeping bag. Using the warmth of 850+ loft 90/10 goose down, the amazing moisture protection of Ultra-Dry Down, and a micro-weight 10D 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 conscious cycle tourers, and ultra light walkers. Its size and warmth rating works well as a booster bag, slipping inside another sleeping bag to add one or two seasons to its rating. The Ultra-Dry Down protection makes it an impressive hard-alpine or adventure racing sleeping bag, where down has never before been a viable option, and weight is simply not tolerated.
The Spark compresses so small, Sea to Summit had to re-engineer their compression-sacks to make one that reduced sufficiently.
The secrets of the Spark’s warmth to weight are in the premium quality down and micro weight shell and liner fabrics, the 1/3 length light-gauge #3 YKK zip and the sew-through transverse baffle construction.
The Spark is cut as a close-fiitting mummy bag. The full hood, foot box and short zip maximise fit and warmth while keeping weight and bulk to a minimum.
