Re: Cold weather tree stand
Man you have your work cut out for you. That thing is gonna be huge. You may want to look into the electric powered vests and socks, they make some very high quality units, expensive but they work well.
Get on the ground and your options open up considerably. I'm sure I haven't told you anything here, but you are asking for quite a bit out of portability. That much canvas in a tree will sorta defeat the stealthy part of a treestand anyway, not to mention wind noise from the canvas flapping.
If you are willing to stop at waist high, your options open up. use the "shooting rail" on a gun type stand as an attachment point as well as the base. You will need the two man style ladder stand probably to avoid a fire situation up there. Wind will still be a problem I would bet, and windy days are the coldest.
