Best Bikini Underwear for Men of 2025

"I switched from Life string bikini. These have more stretch and thinner. They don't slide down and the front is better designed. Comfortable for a larger package. Fair pricing too. I recommend these briefs."

"As a minimalist in loin apparel, I find many minimal briefs overly complicated. The U.S. Polo Assoc. bikini briefs are perfectly designed for anatomical cover, support, and comfort. I appreciate the texture of the fabric which blends predominantly cotton with polyester and spandex."

"I love the feel and fluffiness of the material. I would definitely recommend it."

"I wish I had found these years ago! After years of searching for underwear that fits properly, I finally found the best fit ever. They feel almost like I'm not wearing anything at all. However, I wish there were more color options in Large size. The durability has been exceptional since I started wearing them in 2017, with only a few minor issues."

"I love the bikini style; it's almost like going commando. My friend gifted me Avidlove, and I was pleasantly surprised. The material is thin yet keeps everything cool. I find the pouch very accommodating, and it sits perfectly without showing any crack. I’m a 34 waist and the large fits just right, providing comfort without panty lines."

"I usually prefer boxer briefs, but they often don't fit well. I decided to try these bikini style underwear, and I'm glad I did! They are incredibly comfortable, don’t ride up, and I sweat less. The comfort level is much higher, and I feel sexy wearing them."

"I think it's funny that these exist. I don't know much about polo, but I really like this underwear. The tag sewn on the front, reading U.S. POLO ASSN., is a bit unnecessary and can sometimes cause itchiness, but that's just a minor issue. Overall, great price for a good product."

"Honestly, the price is fantastic! They fit like a bikini, which I love, but the strap design isn't as comfy as I hoped. I think I’ll wear them, but I could be more comfortable. They feel durable, and I'd repurchase them, but my go-to brand is still Jockey. For a budget-friendly option, they are a solid choice!"

"I absolutely love these underwear! They fit great and are very comfortable! I'd definitely recommend them!"

"These are absolutely fantastic! They fit well, feel great, and look amazing. The fabric is high-quality, but I did find those fabric tags a bit bothersome. I had to cut them off myself."

"I love the way these feel! They show everything perfectly and fit nicely in the pouch. Super comfortable, I hardly notice I'm wearing them."

"I first bought Avidlove underwear back in 2017 and I still enjoy them. They are well made, stretchy, and offer great support. Not too revealing but still flattering, a great addition to my collection."

"I've found these to be the most comfortable underwear ever."

"The fit is just perfect for my needs, and they feel great."

"I'm thrilled that Amazon has these, as local stores no longer carry them."

"I've always wanted to try Jockey Elance underwear, and I'm glad I finally did. They sit a bit lower than expected, but it wasn't an issue. The material feels thin, but they're lightweight and provide good support with full rear coverage. They hold their shape well throughout the day and don't ride up. For reference, I'm 6'2” and 205 lbs, and the size I chose fits perfectly."

"I used to wear boxers, but they became uncomfortable. These bikini underwear are a game changer. They provide excellent support and are so comfortable that I barely notice I'm wearing them. No bunching or riding up—I can wear jeans and sleep without any adjustments. I'm really pleased with how they look and feel. Finally found a style I love!"

"I decided to switch from white tighty whities to bikini briefs. I really like the fit of these new briefs, although I wish they had a better cup design in the front. They do shift a bit, but overall, I'm happy with them. My significant other appreciates how they look on me, which is a bonus!"

"I've found these to be the best underwear I've ever worn. The 2-ply pouch and sturdy waistband hold everything in place, making them feel very comfortable and nice."

"After years of boxer briefs, I decided to switch back to briefs for warmer weather. These are nearly perfect! Initially, the pocket felt a bit tight, but it stretched after a few hours. They stay in place with a comfortable elastic band, and there’s no bunching in the thighs. It feels like wearing nothing while getting the support I need."

"I usually wear Calvin Klein hip briefs, but I liked the feel of these. I bought them in small and medium because I’m in between sizes. The mediums are much more comfortable, though both felt loose in the rear. I wear size 33 or 34 pants, and they’ve held up great in the wash."

“These have become my new favorite underwear. The fabric is soft, they fit comfortably, and the colors don't show any signs of fading. I wish I had bought 2 packs instead of just the one.”

“My new favorite briefs. They are true to US size, unlike some others on Amazon. The fabric is very soft and stretchy, and the colors are vibrant. The price was great, so I picked up a 2nd pack.”

“I like my junk contained, not just covered, and most other briefs fail in comfort with this criteria. But these briefs combine excellent support with outstanding comfort!”

"I find these underwear incredibly comfortable. The waistband stays put without rolling, and there's no annoying bunching up. I was so impressed that I placed a second order!"

"I've been wearing these briefs for 20 years. They still look great on a skinny guy, but I have to order them from various vendors since they are no longer available in stores."

"I've been purchasing these calzoncillos for many years, but my recent order disappointed me. They're now too thin and seem to tear easily, which is a letdown compared to the quality I expected."

"These are the most comfortable underwear I've ever worn! I love the light and supportive material, and the great pouch keeps everything in place perfectly. I was so pleased that I bought two packs, and I wish there were more colors and patterns available. They are definitely my daily go-to!"

"I find these to be very comfortable and they fit just as I expected. They are super elastic and perfect for everyday wear. I’m happy with my purchase!"

"I really like these underwear. The fabric is soft and lightweight, and the selection of colors is great. However, the elastic around the legs isn't quite tight enough for me, and they do slide around a bit. Despite that, I’ll definitely buy more!"
