Spark SP III Sleeping Bag... So small it will fit in the palm of your hand!
Spark Series Sleeping Bags... So small it will fit in the palm of your hand!
ULTRA-DRY Down™ protection and warmth in a minimalist package
Using the warmth of 850+ loft 90/10 Premium goose down, the amazing moisture protection of ULTRA-DRY Down™, and a micro-weight 10D Nylon shell and 15D lining, Sea To Summit 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 cold weather sleeping bag, especially for weight and space conscious motorcycle tourers. It also works well as a liner bag, slipping inside another sleeping bag to add one or two seasons to its rating.
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.
1/3 Zip Mummy
The secrets of the Spark’s warmth to weight are in the premium quality down, the 1/3 length light-gauge #3 YKK zip and high-performance micro-weight shell and liner fabrics.
The Spark is designed as a close-fitting mummy bag.
The full hood, foot box and short zip maximise fit and warmth while keeping weight and bulk to a minimum.
The Spark I is constructed with sewn-through transverse baffle construction. 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 foot-box for even heat retention. The head and neck baffles have been enlarged to trap vital warmth and achieve a lower limit EN rating of minus four degrees.
The sub-zero Spark. Perfect for winter missions where you were previously agonising about not taking a bag at all.
