Comfortably fitted

DanskyAugust 11, 2025

The first time I ordered i think I ordered large and I found out they are not comfortable, so I gave it another trial and ordered XL but this time they look so much perfect, comfortable and awesome. To me I recommend this product to the viewers who are searching for a comfortable and sexy boxers. So thumb up to the producer(s). Read more

Gnarly and comfy.not your dad's briefs.

CustomerNovember 17, 2025

Fit great, feel great, graphics have held up to about 20 wash cycles now and colors are still as vibrant as the day they arrived, they feel great around the ball and gooch area and don't bunch beneath the butt cheeks like other style briefs. Would highly recommend for physical activity as they help cool your cheeks and keep the swapbutt away. Read more

Hilarious T-wrecked Design

JMDecember 4, 2024

These Knobby Down Under boxer briefs are hands-down the most fun (and functional) underwear I've ever owned. I grabbed the "T-wrecked" design because who doesn't want a pair of dino-themed undies that make a statement? As a personal trainer and bodybuilder, I spend plenty of time in the locker room, and these briefs are the perfect mix of comfort and conversation starter. The fit is spot on—I'm 6 feet tall and have 200 pounds of muscle, and the medium-size hugs just right, giving me support where it matters without feeling restrictive. The pouch design keeps everything in place during workouts, and the breathable material (made from recycled plastic bottles!) is a game-changer for staying cool and dry, even on leg day. The real highlight was my girlfriend's reaction when she saw them after the gym one night. I walked into the living room post-shower, feeling relaxed and still riding that workout high, and she immediately burst out laughing. "T-rex? Really?" she said, shaking her head but amused. After the initial teasing, she admitted they were kind of cute—and let's say they got her attention in all the right ways. These boxers are officially her favorite now, and I'm not complaining. If you want to stand out, stay comfortable, and do a little good for the planet, these boxer briefs are the way to go. Just be ready to flex your sense of humor, quads, and maybe your relationship skills when rocking them. Read more

Whats not to like?

Rich ReviewsNovember 29, 2024

These boxers are pricey (to my standards) but comparable in price to other luxury branded clothing. I like the name of the product, and detail that they’ve put into designing these boxers (from packaging to the product itself). The material is mesh, and soft. Who would have thought that you could make this from recycled plastic bottles. As for a comparison, these feel like they’re made like under armors/nikes. The only draw back to these boxer briefs are that they are lacking access to bring out your boys, not an issue for some, but a major one to others. But with that said there’s ample room there, and these are comfortable. Read more
