Does Rab make good sleeping bags?

At first glance the Mythic is an incredible sleeping bag. Rab combines premium 900-fill power down, silky Pertex Quantum fabric, and a minimalist zipper to create a bag that’s plenty warm yet also ultralight.

Down insulation in most sleeping bags range from about 400 to 900. Down rated 500–650 is warm enough and light enough for most conditions, and 800–900 fill is used for very lightweight and very cold-weather gear.
