The Spark - a delicate balance of size, weight & warmth.

Comfort Rating Lower Limit Rating Extreme Rating
Spark I 12℃ 8℃ -5℃
Spark II 7℃ 2℃ -12℃
Spark III 2℃ -4℃  -20℃

The clever combination of ULTRA-DRY Down, the micro-weight 10D nylon shell and the 15D lining ensures that your bag stays dry & warm - wherever you are. The Spark is perfect for the weight & space savvy, or alternatively it can be used as a liner bag - adding one or two seasons to it's rating when slipped inside another sleeping bag.

The secret to the Spark's warmth to weight ratio is in the premium quality goose down, the 1/3 length, light-gauge #3 YKK zip and the high performance micro-weight shell/liner fabrics.

The close-fitting mummy bag includes a full hood, foot box as well as a short zip to maximise the fit and warmth whilst keeping weight and bulk to a minimum. A box-wall baffle construction is utilised for heat retention and the head/neck baffles have been enlarged to trap vital warmth.
