I was all undergarments after every hunt, sweat or not. As for outer layers, probably every 3 hunts those get washed too. The house we bought has a greenhouse on back of the garage, but now it is my camo storage room. All my camo hangs out there year round, all windows open, so it smells fresh as a daisy all year. To and from hunting spots, I use a Scent-Lok bag. as for my boots, I keep them in a box with leaves on the bottom.
