The Filson's midweight Draftsman Canvas Pants combine ruggedness with classic lines. The midweight 9.5-oz. Panama canvas is tightly-woven in a basket-weave pattern for structure and excellent durability. 1 percent elastane incorporated into the weave gives the fabric slight stretch while maintaining its high resistance to abrasion and wear. The side-seam front pockets provide clean lines and sport an additional welted pocket for coins or small items. One flapped and one welted rear pocket each feature button closures, and heavy-twill pocket bags ensure longevity. Equipped with a traditional zippered fly and button-waist closure as well as 7 belt loops to prevent a sagging waistband.
