THE original waterproof boot. This all-season style gives you tireless waterproof performance and instantly recognizable work-boot styling. Other essential features include 400 grams of warm, down-free PrimaLoft® insulation, a padded collar for a comfortable fit around the ankle, and a rubber lug outsole for traction. They're responsibly made, too, with eco-conscious leather uppers and ReBOTL™ fabric lining. Timberland supports responsible manufacturing of leather through the Leather Working Group.
