I wish I had a dollar for every time my wife has said, "whew, you are a hot box". When I paddle and portage more often than not you will find me wearing a visor so I don't overheat and self combust. So I am in sympatico with you on the overheating issue.

So take it from me and get the fish hawk 30 degree bag. I too almost got the 40 degree bag for the identical reason but purchased the fish hawk and am so glad I didn't opt for the 40 bag.

First off, the rating system is flawed........as in overly optimistic. There is no way I would want to be in my 30 degree bag in 30 degree weather. Trust me. I had it in the low 40's this fall and while I stayed warm because of fleece hat, fleece socks and silk underwear, I was on the verge.

I also used it in the "Q" during early July and it was perfect. As some who have experience here on QJ have already suggested be sure and wear some type of underclothing at night lest the oils/dirt/grime/mud/bug spray/blood/fish slime/etc. soil your inner sanctuary. ;D

Oh, one last bit of advice.........when you roll your mat be careful to allow time for the trapped air to escape the valve. There are murmuring of air leaks at the ends. My suspicion, just a hunch mind you, is that inordinate amounts of pressure are being exerted when rolling the mat.
