Sea To Summit Spark Sleeping Bag SpI Regular
Using the warmth of 850+ loft 90/10 Premium goose down, the amazing moisture protection of ULTRADRY Downâ„¢, and a micro-weight 10D Nylon 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 many possible uses,
Its balance of size, weight and warmth make it an excellent summer sleeping bag, especially for weight and space conscious cycle tourers and ultralight fastpackers,
It also works well as a liner bag, slipping inside another sleeping bag to add one or two seasons to its rating.The Spark compresses so small, we had to reengineer our 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.The secrets of the Spark’s warmth-to-weight are in the premium quality down, the half length light-gauge #3 YKK® zip and high performance microweight shell and liner fabrics,
The Spark is designed as a close-fitting mummy bag,
The full hood, footbox and short zip maximise fit and warmth while keeping weight and bulk to a minimum.The Spark I is constructed with sewn-through transverse baffles,
The Spark II is a hybrid construction with box wall baffles placed over the torso to boost warmth around your core and a sewn-through construction at the legs,
A draft tube is sewn over the zip to reduce cold spots in the Spark II and III models,
The Spark III is constructed entirely from box wall baffles including the footbox for even heat retention,
The head and neck baffles have been enlarged to trap vital warmth and achieve a lower limit EN rating of -4°C.Shell: 10D UL Nylon treated with DWRLiner: 15D nylon soft touch, high density weave850+ loft Ultra-Dry Down® (90/10 European goose down)1/3 length #3 YKK zipperSew-through transverse baffle constructionIncludes lightweight Ultra-Sil® compression bag, mesh storage cell and laundry
