Sea to Summit Spark SpII 35ºF Ultra-Dry Down Sleeping Bag

$379.00 - $399.00
Using the warmth of 850+ loft 90 / 10 goose down, the amazing moisture protection of Ultra-Dry Down™, and a 10D UL Nylon DWR treated shell and 15D lining, Sea to Summit® has created a great warmth-for-weight minimalist sleeping bag.

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 secrets of the Spark’s warmth to weight are in the premium quality down and high performance micro-weight shell and liner fabrics, the 1/3 length light-gauge #3 YKK® zip, and the sewn-through transverse baffle construction. 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 is cut as a close-fitting mummy bag. The full hood, foot box and short zip maximize fit and warmth while keeping weight and bulk to a minimum.

Following a successful 1984 climb up the north face of Mount Everest, one of the summiteers, Tim Macartney-Snape decided to return six years later so that he could do what no one else had done - climb it starting from sea level, that is from "sea to summit".

For this trip, in 1990, Tim swam in India's Bay of Bengal and then set off on foot across the Gangetic plain toward the distant Himalayan foothills and four months later, set foot once again on the highest point on earth. Tim's solo ascent of Mt. Everest was named the "Sea to Summit" expedition.

Back in Australia, he joined forces with friend Roland Tyson to build a business that could make use of their knowledge of the outdoors to create truly ingenious, well-made but affordable outdoor equipment. They named their company Sea to Summit® after Tim's expedition and the business prospered. Today the Sea to Summit brand continues to provide innovative gear and serves a growing band of outdoor enthusiasts all over the world.
