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.

Good
"Good fit, excellent moisture control, very comfortable"
Awesome, comfy and stay dry.
"Awesome underwear! They help keep me dry as I work in a factory and helps keep that area drier to avoid ingrown hairs on my thighs."
DUCKWORTH IS AWESOME
"All of my Duckworth gear is the best of the best. And your business model sold me several years ago. Ranch to me just the way I like it. Under product use I selected other because I use it for everyday everything. But I started using it as a fly fishing guide, a hunter and a wannabe cowboy."
Great quality, loose fit
"The quality is excellent, like everything else I own from Duckworth. The fit is a bit looser than expected, when compared to other brands. I expected them to be form-fitting, but I’d describe them as fitting somewhere between boxer brief and boxer. I’ll just take this as a sign to do more squats."
I bought one pair as
"I bought one pair as a ‘try it and see if I like it’. The jury is unanimous, it is a superb product. Fit, feel and function all were great. I’ll buy more!"
Amazing
"Comfortable for warm and cool days. Feels great while running, does not climb up the leg. I use these for daily wear and whatever comes my way. Large was a good size with a 36in waist."
Need XS version
"5’5 140 pounds, and the small fits a bit too loose. Wish there was a XS fit as I like them to be a little fitted. Have had to dry on high heat one time to shrink them slightly."
Comfortable.
"Very comfortable briefs."
"High quality as always. USA made"
