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.

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."

The Ascent is a great all rounder sleeping bag is rated to keep you toasty in a light frost. With 750 loft down they are packable enough to throw in your backpack, and also appropriate for car camping adventures. With the ability to open the bag up for use as a blanked, but two zips, one for the footbox, and the other along the side where you can zip the male and female bags together. The hooded bag is roomy with its rectangular shape and internal zip pocket on the inside for overnight storage of small items you want to keep close at hand. The Ascent is a great all rounder sleeping bag is rated to keep you toasty in a light frost. If you are particularly susceptible to the cold, it may be worth pairing with a liner
