What's amazing to me is a standard cotton poly blend or even 100% cotton shirt stinks in a day on me but I can wear my wool shirt for most of a week including workouts and the shirt is fine. Even if I stink in the shirt air it out for a day and it's good.

I'm down from about 1.5 shirts a day in the wash to about 2 per week depending on how often I spill things on myself. Add in air drying instead of the dryer and it is a big difference in laundry energy use.
