I posted this in gadgets and gear originally but it didn't get any bites..so I guess ill try it here 
Hunting season is starting up before we know it, and i'm not quite ready to say the least. My usual hunting apparel has worn out over the last 5 years. I replaced my hunting jacket last year with a nice Cabelas parka (scenk-lok, gore-tex, the whole shibang) that is more than enough to keep my upper body warm and dry. However, my bibs that I usually wear, have just been replaced with a pair of Cabelas MT050 Gore-Tex Scent-lok pants because the price was too good to pass up. Unforunately, they aren't insulated. I have under armour cold gear thermals that do a decent job, but my lower body will definitely need a good middle layer, which leads us to...
What's a good middle layer for hunting? Being that I have a good base layer and a good weatherproof outer layer, I need a good middle layer that will insulate the best I guess? I was thinking wool, but have no idea. The best thing I've seen so far is this http://www.cabelas.com/product/Brow...tt=full+curl&WTz_l=Header;Search-All+Products
I would really like to keep this around $50, because if it were much more (aka $100) I would have just been better off getting the insulated version of the pants
Thanks for the help guys...hopefully there is something out there for me.
