I use these overpants during cooler weather. Easy on & off without removing your boots and they're tough enough to take a beating & outside pockets make stopping for gas no hassle. I like their buffalo hide products - no armor, but good thick protection. Great people to deal with. Pants on sale right now too @ $80!
