I spent my first night out in this bag over the weekend. Temps fell to in the 28-32 range. In base layer, and merino wool socks, this bag performed very well on top of a 3/4 length ridge rest. The chest baffle sets this bag apart as it traps the air your body has heated inside the heating compartment and blocks new unheated air from entering. Many 20 deg bags at this price point lack this feature. My experience was that the minimal amount of recirculating air caused the same air to be warmed by my body heat all night, which resulted in me being warmer in the morning, when air temps were cooler, than I was when I first crawled in. I expect this bag would be comfortable at or below its state 20 degrees given proper layering, but I can imagine being miserable in it later this spring.
Great loft, good zippers (top zipper smooth, bottom zipper locks well then zips smoothly). Stuff sack is REALLY small, but compresses well and stitching/buckles seem to be high quality. It lives in the included cotton sack when not in use. I am rating this bag based on my needs--a spring/fall bag that will typically be packed for 1-2 night trips less than 5 times/year.
