Hey. I hate chaps and usually neglect wearing them. I thought I'd just buy a few pairs of chainsaw pants on treestuff to try them out for me and my guys but man are they expensive! Questions- Is there a particular brand that's best? How many pairs does one guy need? How often do they need to be washed? Do you just throw them in the machine? How hot are they? It's cold here in the winter so I wear thermals now but it's hot in the summer.
