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.

Got these for my 13 year old son whose pretty picky about his boxer briefs. Typically he wears meundies and these compare favorably. The different patterns are cool, but that's subjective. The material is nice and soft, yet durable. Should hold up well to washes over time. My only gripe is that these are pretty expensive, paying a lot of premium for the cool prints.

The quality and design of these boxers is really great. The design is awesome and the construction of the pocket is really well thought through. The material is both smooth but doesn’t ride up my husbands legs. They are comfortable and don’t feel suffocating either.

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.

I'm really digging my new pair of Knobby Down Under Breathable Underwear. They are a polyester and spandex blend and are lightweight and breathable. The fit is true to size and I really like how the waistband is much thicker than my others. They're flyless which I'm used to and I like how they've gone conservative when it comes to the pouch in the front. What can I say about the graphics on these boxer briefs? You can't miss 'em! Bright, bold, and they could almost glow in the dark. I believe I'll be adding more of these to my wardrobe very soon.

These boxer briefs are outstanding. Really high quality, super comfortable and the design on them is sick. The colors are bold, accurate and the look is unmatched. These are definitely on the expensive side for me but the difference in quality compared to the 5 and less stuff I usually go for us night and day. These are shaped perfectly, fit like a glove and I hope they stand the test time because they're my favorite pair. Super fun and high quality.

These Knobby "Gotta Be Squidding" boxer briefs are a fantastic blend of style, sustainability, and comfort. The creative squid design and vibrant colors are a fun departure from traditional underwear. The breathable fabric, made from recycled plastic bottles, is incredibly soft and comfortable against the skin. The flyless design and pouch provide excellent support. I'm impressed with the quality, comfort, and eco-conscious approach of these boxer briefs. Highly recommend!
