Ultralight versatile 3-seasons down sleeping bag.
Product description for Sea to Summit SPARK SERIES - SP I REGULAR from our collection of Outdoor Sports & Fashion:
The SP I Regular is the most lightweight sleeping bag that SEA TO SUMMIT launched so far, equipped only with the necessary - perfect for adventure racers.
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, SEA TO SUMMIT has created one of the best warmth for weight minimalist sleeping bags available. 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 YKK zip and the sewn-through transverse baffle construction. The Spark by SEA TO SUMMIT compresses so small, they had to re-engineer the compression-sacks to make one that reduced sufficiently. The Ultra Dry Down™ protection makes the Spark by SEA TO SUMMIT an impressive hard-alpine or adventure racing sleeping bag, where down has never before been a viable option, and weight is simply not tolerated.
