I got the full face mask and boonie hat with mine, which work great. The day I killed that doe in Iowa, there was 3-4 inches of snow on the ground with the steady Iowa breeze, temp at 30 deg.....and sweated like a pig! I did hike in more than a mile from the truck though, and mostly uphill sneakin...it'll keep ya warm, fo sho!!! I covered alot of ground fast, as I knew where the deer were holed up, from using the spotting scope at the truck. Came to full draw, while the deer was broadside, looking at me...she stomped once, and never knew what that was that snapped that rib....Can't wait to use it more, this fall!!!
