Description

The Spark Ultralight Mummy Sleeping Bag Series spans everything from an ultralight down-filled liner, to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and no-frills design to provide cutting-edge performance.

Ultralight does not mean ultra-tight: The Spark mummy sleeping bags are snug but still have adequate wiggle room for the performance-oriented, backcountry user.

Frequently Asked questions

Suitable for cooler temperatures?

Yes. The -15°C or possibly the -8°C will work in late Autumn. The Spark -15°C will take you down to winter temperatures when paired with a greater than 3.5 R-Value sleeping mat like the Comfort Light Insulated.

Really suitable as a sleeping bag liner?

Yes. You could use the Spark 10°C, or even the Spark 5°C to boost the performance of a bag for cold-weather use. Adding one of these to a -6°C bag might make more sense than buying a -17°C bag for occasional winter use.

Able to be zipped to another sleeping bag?

No. Even though the -8°C or -15°C have full-length side zippers, they are not designed to be coupled to a sleeping bag with a right zipper (for instance the Flame)
