Description
Where we come from comfort in the right places matters.
Duckworth's Men's Vapor Brief keeps you comfortable where it counts with natural American-grown Merino Wool spun and knit into our proprietary Vapor Wool fabric blend.
Our Vapor Wool is naturally antimicrobial (odor-free) itch-free cooling breathable quick-drying moisture-wicking and oh-so comfortable. Vapor Briefs feature a functional fly and a brushed elastic waistline that's soft against skin and resists riding up.
Even in the most hot and humid conditions these briefs are guaranteed to keep things dry and temperature regulated. American-made with American wool.
NEW FOR 2026: The vapor collection now features an updated vortex-spun yarn construction designed for greater durability reduced pilling and longer-lasting performance. This improvement strengthens the fabric while preserving its ultralight breathability and soft feel that continues to improve with wear and washing.
Please note: We cannot accommodate returns for opened briefs.
