Excellent craftsmanship and thoughtful design. No gimmicks, just a functional item that simply works. Haven’t tested it below 32 degrees, but it seems accurately rated. As noted elsewhere, the zipper is outstanding, no stress getting in or out. The hood is well designed with a super efficient draft collar. Ample footbox provide comfort, seems over stuffed for warmth. The dimensions are just right for me (6’ 180 lbs), allows side sleeping without the bag fighting the constant turns, but not so loose it wastes efficiency. I sold two bags/quilts (10 deg and 25 deg) to finally get the right one.
