“The comparison of specs between this 15 deg bag and the very similar SD Mobile Mummy 5 deg bag (Item#163HX) makes no sense to me. This is a smaller bag in length and girth, with 4 oz. more of the same rated down filling. If that is correct it should have more loft, more insulation, and therefore a colder temperature rating, not warmer. Is this temperature rating for women, for whom the EN Standard assumes a higher sensitivity to cold? If so, then the specs should say it is for women, and give the equivalent EN rating for men, more like 0 deg. If not, then what is wrong with these specs, or my logic? ”
It is a Womens Bag. They Failed to mention.
