If you are looking for an ultralight sleeping bag , you are in the right place. The Spark 7c is incredibly lightweight and packs ridiculously small making it ideal for anyone looking for a minimal summer sleeping bag for fast and light adventures. The mummy shape can feel quite restrictive for some people and the 10D fabric require careful handling to prevent any damage. This option is good for someone who doesn't want to sacrifice high quality down insulation, while keeping their gear to a minimal weight.

Fit tip:

Performance and Comfort in a Lightweight Package

"The Spark 7 is one of the more compact sleeping bags on the market. It is really comfortable with the 3/4 zip and even the little features of the plastic flaring that goes over the zip to stop it from catching the fabric and making it more comfortable for sleeping. I find while this bag is rated to 7 degrees, with a small amount of clothing on during the night it is quite comfortable down to 5 or 6 degrees overnight temps."
