The Coastal Boot Yukon Work Boot features water resistant full grain leather uppers, which are 2.0mm to 2.2mm in thickness. Removable Smartmask sock liners tame the harsh impact delivered when standing on concrete floors, and Cambrelle lining is throughout the interior of the shoe for excellent abrasion resistance and moisture management. The outsole is gas-, oil- and grease-resistant, and the wide channel tread design prevents the accumulation of dirt and grime. Available in black or brown, and sizes 7 to 14.
