Kristen,
I cannot help but good-naturedly laugh at you. I remember many times going out to the stand at -10 or worse. The last few years have been too warm in fact (lows in the 30s and highs in the 50s). But, having lived in Minnesota all my life, I am accustomed to it. I couldnt handle your heat, I would melt. I have read a local author up here (Gary Clancy) quite a bit and I seem to recall him saying that the heater body suit was awesome. You could do an internet search on him or contact him at Outdoor News (outdoornews.com, I think).
