You are the second person to mention the Wiggy's in a week. We went on an overnight in Wyoming about two weeks ago, and the nighttime temps dropped into the lower 20s. Lot of folks found out those temp ratings are about survival, not comfort. My cold weather bag has shrank a little over the years (my story and I am sticking to it). One of the other Dads in the pack mentioned that he bought a Wiggys as a deployment bag, and absolutely loves it. Tells me it is the best thing going by far. I'm willing to put out the cash, but it would make me feel a little better to have another testimonial, as I gather these are not exactly mainstream bags. Would love to know what you think of yours.
