Over the decades, I`ve dealt with many vendors.... Campmor, Eastern Mountain Sports, Eddie Bauer, L.L. Bean, and others. The last few years, I have gravitated to Bailey`s (Laytonville, Ca.), they cater mainly to the logging/arborist trade, and carry LOTS of clothing for the working man. Pants, jeans, and jackets by Carhartt, Ben Davis, Dickies, Viking, Wrangler, Big Bill, Key, Wild Ass, Berne, and Prison Blues ("Made on the inside, to be worn on the outside"). All kinds of tools, chainsaws, you name it....anything timber-related, they have it.
Decent prices, too.
My other favorite is Duluth Trading Co., They have a lot of top-quality, hard-wearing gear. Their commercials crack me up, too
