Query: Browning excelsior sleeping bags

This is a really well made sleeping bag. It has a nice cover and great stuff bag and compression straps. The bag is roomy and comfortable within it's temperature comfort range. The problem is the temperature rating. I own the 0 rated bag and -30 bag. I have used the 0 bag in cool weather. At about 30 degrees the bag gets cold. I'm not sure how they came up with the rating. All the other bags I own are much closer in their rating. I haven't tried the -30 bag yet, but it doesn't appear to have anymore loft than the 30 degree rated one.Browning Excelsior 0-degree Oversized hooded Sleeping Bag
