Sorry this took so long for me to post but I got busy with the holidays and all that crap my wife makes me do. I'm sure you guys understand. Anyways I have to say that this coverall is by far the warmest thing I've ever worn. I used it for four days straight when the highs never got out of the teens and the lows at or below zero. I never even remotely got cool never mind cold. It has heavier amounts of insulation in the butt and back than it does in the legs and arms. This keeps the core warm and still allows you to move your arms and legs freely. I did shoot my compound with it on and there was no string interference at all. The handwarmer it comes with is a nice addition. I like that it snaps on to the suit so it doesn't sag. I put one hot hands packet inside it and my hands were toasty. The built in carry bag is a nice touch TOO. It's a little tricky at first to get it all in the bag but once you figure it out it only takes a few seconds. Now you may be thinking why bother with the bag I'll just wear it walking to my stand. I did that the first day and I was sweating like crazy when I got there and I didn't even walk 1/2 a mile. I strongly recommend packing it in and putting it on at your stand. The carry bag has a sewn in shoulder strap. Every night I did walk out with it on but I unzipped the chest and legs. Plus I didn't care if I was sweating when I got back to the truck since I was headed home. Now I did not do any all day sits but I bet this thing could keep you warm for 10 hours or however long you need it to. As far as layering goes you don't need much. I wore my Under Armour 5.0 base layer with a mock turtleneck on top and my early season lightweight bibs on bottom. I hiked in with that on and put the suit right on over it. That was plenty. It also has a hood that can be removed but I left it on. In fact I wore my safety harness under the coverall and unzipped the back of the hood just enough to feed my tether strap through. Worked great. I bought this for half price and it was still $220 so it's a pricey garment. If I had to pay full price that would have been a different story. Last I checked the Cabelas website they had them marked at $250. Still worth it at that price if you ask me. Our deer season here is over so I won't get much of a chance to use it for a while unless I go after some coyotes or go ice fishing. Since you guys in Ohio have the whole month of January to hunt you've got plenty of time to put it to the test. If you decide to order one I suggest getting a size bigger than you normally do. I'm 6'1" 225 and I got a 2XL and I'm glad I did. Fits perfect with some room for extra layering if I ever need it. Hope this helps and feel free to ask me any questions.
