Outer layers usually hang outside on the porch in between hunts. After several hunts it gets washed. I have several sets of long underwear. I only wear those once each,thenthey gets thrown in a pile to be washed.

Washing consists of straight baking soda. I usually try to do a line dry, but if that isn't practical I'll go with the earth dryer sheets.

When in transit and from season to season, all the clothes are put in a couple great big tupperware type containers.

Seems to work okay.
