I use those Tyvek suits at work every time I have to do some electrical work under a building.I think you have a great idea. They are quiet and comfortable. I would give that a try but we never get any snow here. If I ever do go hunt in the snow I won't have to buy new camo now. Thank you for that tip. Those suits cost about $6 each and they are pretty tough so 2 or 3 could do for a week long trip.
