- Modeled after Duckworth's best selling Vapor Briefs
(an item they've dubbed the World's Best underwear), the Vapor 3/4 Legging's unique shin-cut length is designed with ski, fishing, and hunting boots in mind. Why do that? Well, imagine this: no more need to cram that extra fabric in or over your boot cuff, while maintaining all the benefits of Duckworth's proprietary Vapor Wool fabric. And what are those again? In no particular order, we're talking moisture-wicking, quick-drying, antimicrobial (odor-free), and itch-free baselayer goodness. Our 100% American-made Vapor Skier's Legging is also semi-loose-fitted, with a full inside leg gusset for maximum mobility and comfort, and boasts a brushed waistband and functional fly for extra ease and comfort. Don't head out for your next cold weather adventure without them.
