I wear my pants several times without having them dry cleaned. I used to wash them but not anymore.
I wear tights underneath them and the pants do not smell after use. Then again the tights I wear are ankle length and I think the fabric used on the tights is virtually dry after one game. I do wash everything else after one use, but not my pants. No need to in my opinion. But hey we all do not have the same body order issues either.
Peace
