i v wrote a review of MontBell Super Spiral Hugger #5 Down Sleeping Bag: 40 Degree on February 24, 2012
Great bag! Took it on a couple of trips. Love the elastic quality. Great loft compared to similar down bags. No down leaks. Looks solidly manufactured. Light for a 650 down bag. On the fit side, I wear size large tops and I'm 5'10''. The bag fits me very well. And while I think it can accomodate broader shoulders, it appears that I am pushing the limits lengthwise. I doubt very much a 6 ft person will fit comfortably. Other than that, a top notch bag!
