ULTRA-DRY Down™ protection and warmth in a minimalist package

“When you need a sleeping but don’t want to be weighed down by one, what’s to be done? Until now you either slowed yourself down with something inadequate or took the spartan option and suffered without. Now the Spark has changed the game completely. Neither comfort nor performance need be sacrificed!” Tim Macartney-Snape

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, 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 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 #3 YKK zip and the sewn-through transverse baffle construction.

The Spark compresses so small, we had to re-engineer 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.

1/3 Zip Mummy

The Spark is cut as a close-fiitting mummy bag. The full hood, foot box and short zip maximise fit and warnth while keeping weight and bulk to a minimum.
