A guy I worked for in college was just telling me about this over the Christmas holiday. Avid hunter is an understatment - he spent six weeks in Ohio hunting a 200+ buck then several other weeks in Pennsylvania, West Virginia and Kansas. He said you get this on when you climb into your stand (ladder for him). There is a zipper like conneciton in the front and when you need to get out, unzip, and you're there. He said while others were going back to camp from the cold, he was comfy cozy in his heater suit. Sounds like a good idea.
