These need better quality control. I bought several pairs an one had stitching come undone after two or three uses. Another (my favorite color) developed a hole in the fabric after two washes. Don't get me wrong - these fit and feel great, but they should last longer than just a few wears.

This is the best underwear I’ve ever owned. Will absolutely be buying more. Hopefully this product stays around for the long run.
I love the way these look and feel. However, after only a day of wearing them, they are already starting to get pilly. And I only washed them by hand in cold water and let them air dry. Nevertheless, I love the look and feel and so does my wife. :)
These are the best underwear I’ve ever owned. I’m 5’10”, 170lbs and they fit great! Will be buying more in the future.
These fit perfectly! Great colors, easy to rinse and hang to quickly dry.
This is the best underwear I’ve ever owned. I absolutely will be buying more in the future. I am 5’10, 170 lbs., and a medium fits perfectly. It can occasionally ride up slightly but I never notice until I am changing.
These are lighter than air and I love the fabric...I rated a four star as they tend to ride up a bit in the rear
Great product!
I wear these daily, can't recommend them enough as the perfect pair of boxer briefs. No riding up, no adjusting, no issues.
Comfortable, great fit, and well priced
Pros: Comfortable, good fitting, stays in place, soft, fast drying.
launders well.
Cons: no fly
Much better fit than large, anyway I can still exchange first pair purchased? Fabric and color is great. Thx.
I mean, I’m not saying you should rub butter all over yourself, but if you did, the feeling may be comparable to this pair of boxers. Incredibly lightweight, yet supportive, smooth, and stylish. JA does it again!
These feel so great. They fit prefect.
The material is nice and lightweight. Though, I do wish there are smaller sizes available. I’m a 26” waist and a size S was just slightly loose on me. Overall, a good product and the customer service was very helpful!
Best underwear ever. Amazing quality and attention to detail. You get what you pay for.
Extremely comfortable. Will have to get more.
Really the best underwear, almost like wearing nothing, yet great support and feel. Excellent product.
Love these pair of bikini boxers!! The fabric is sooo soft yet supportive. The cut of the boxers accentuates the goodies but provides the right amount of coverage and support. You can wear these on a date night or under everyday clothes. These Jack Adams Bikini Boxers are sooo amazing and perfect that I have 5 pairs in different colors.
The best yet. Good fit.!! Soft and comfortable!
Like wearing nothing @ all.
Very comfortable and accentuates your "features" without being overly risque. Excellent for everyday wear and just lazing around in.
Just like my other Jack Adams underwear, these are a great fit and very comfortable - probably the best feeling underwear I currently own. The fit is true to size and accentuates everything nicely.
These made me feel as attractive as the model. They fit perfect and compliment everything nicely. Jack Adams spares no expense in delivering comfort and style.
I was a little nervous when I made my purchase. Once I received and gave them a try I became a true believer. Amazingly soft and 5 stars for the fit. I'll be back.
