    Great quality and feel

    These are the best underwear I’ve ever tried! In a market that is flooded with products making large claims Krakatoa are everything they say they are and then some. They are super supportive, soft, and comfortable it really is like wearing nothing. The quality is top notch and wear is equally as durable. Well worth the money and really appreciate the customized fits between the different styles they do not all fit the same. Thank you! I highly recommend these and have since thrown away all my other underwear! Thank you for making such a great product!

    How could they be this good?

    For years I was a tighty whitey guy…it was just what I wore. Never liked boxers…they just didn’t have the support I wanted. I tried a few other brands that were better than what I was wearing, but they were just ok. But when they started wearing out and I needed some replacements, I started doing some searching and research. Krakatoa came to my attention, and boy am I glad they did. The half price first pair offer was too good to pass up. My trunks came in less than a week even cross country, and I fell in love on the first wearing. Comfortable, supportive, stylish, and (according to my wife) sexy…what more could I ask for? The boys were supported in comfort, the horizontal fly is a game changer, and the micromodal fabric is just amazing. I couldn’t get an order off fast enough. And the military veteran’s discount was a nice plus. Don’t change a single thing…they are perfection!

    Hubby loves these

    This is my second order and these are the best men’s underwear in my female perspective. They are so soft, right out of the package- like soften butter… and they hold up so well… the first pairs I got my husband right when this company started which was at least 2 years ago and they still are holding up well with being washed often as he always picked these ones to wear …. So for Valentine’s Day- he got 7 new pairs!!

    Wife loves them

    They’re comfy but the biggest thing is that the wife loves how they show off the package! All the pairs I’ve gotten have now become her favorite. Besides that they do fit really well.

    Unbelievably comfortable!

    Love these so much! I was struggling to find a pair of underwear that was supportive but not uncomfortable during 12 hour shifts, these are perfect! I cannot recommend them enough and I will be ordering more!

    Buy them, seriously.

    So I was a little skeptical only because the marketing was really good, and sometimes that doesn’t necessarily mean that the product itself will be good, but I trusted my gut after hearing the founder talk about all the aspects of the design and their functions, and I’ll be 100% honest - I have never known this level of comfort in my life. These are by far the most comfortable and well designed underwear I’ve ever worn. If you had any reservations, let them go, you’ll thank me later once you have some on.

    Love and light,

    - Cameron from Austin

    Best There Is

    To my fellow humans who have equipment to store comfortably, you can’t get any better storage gear than Krakatoa. It fits. It’s super comfortable. It’s sexy. It is well designed. I tried at least 5 other brands, all purporting to be the best. They lied. Krakatoa is indisputably the BEST THERE IS….PERIOD!

    To the window!

    To the window - to the wall. My legs don’t stick to my balls. The pouch leaves me standing tall. All the other underwear fall. It makes me wanna give Krakatoa a call. You won’t find these in the mall. They give me unmitigated gall. They leave me swaggin’ down the hall. Get Krakin’ and get some of these, y’all.

    Flawless underwear

    I have to day, at first I couldn't believe that underwear would cost that much could be any different than what I could get in the store for a much lower price. But I was wrong, no chafing, no rolling, bunching, pinching, no adjustment needed, easy to whip it out at the john without manipulating a bunch of fabric to free the beast. I took them for a run and the kept everything in place and wicked the moisture away from all the hot spots. In short they were amazing and I washed them that night to wear them again! Once I trial ran the first pair I jumped right back in and ordered 10 more pair, these are the best, most comfortable underwear I've ever had in my life, and there's no way I'm ever wearing anything else

    Best briefs ever for an old guy!

    I saw these briefs online and was intrigued by the product description and 'wow' reviews. I bought two for starters and, after wearing them, ordered a bunch more. They are very comfortable; the waist band does not roll over and the pouch cradles and lifts my ba**s for the best support I've ever experienced in mens' briefs! I will buy more!
