Kraig Becker on The Adventure Blog is one of my most trusted gear reviewers.
He’s been using this innovative sleeping system since 2018:
… The model I tested was rated for use in 10ºF (-12ºC) and the entire system (sheet and comforter) weighs just 3 lbs, 13 oz. (1.73 kg) for a large model. An equivalent-sized version rated for 25ºF (-4ºC) temperatures weigh more than a pound (.45 kg) less. Make no mistake, there are other sleeping bag options that weigh less, but few will deliver this much comfort. …

It looks great. Ideal for adventures where weight is not a major issue: Bikepacking, Kayaking, car camping, etc.
For long hikes I’ll stick with the lighter (more expen$ive) Enlightened Equipment Revelation Quilt.
