Husqvarna chain-saw protective "summer pants" can be worn all day just like regular pants and are machine washable. The articulated knees reduce pull at the waist when bending and stooping, keeping the waist from dragging down excessively. Large, vented front and back pockets, as well as a cargo leg pocket, provide ample storage while the Caribou outer fabric is very durable, water-repellant, cool, and, of utmost importance-comfortable. Six layers of chain-saw protective material cover the front, sides, and calves while the backside is a fully breathable (non-saw-jamming) polyester fabric. Conforms to OSHA, ASTM F1897, ANSI Z133.1, and ULClassified. We suggest buying pants slightly loose and using suspenders. This popular wearing style among woodsmen greatly improves air circulation up through the waist, where heat tends to build. Buttons are inside for suspender use, and loops along the waist are for a belt. Suspenders available. Call our customer service department for details.
