    Krakatoa

    As someone who has changed body composition for the positive, support is a huge issue for me and the compression on the legs is awesome. The overall comfort is equally awesome.

    More importantly is the owner’s attention to his customers

    He certainly supported me and I in turn will be doing the same for him.

    The best customer service as well as the best briefs

    I can’t imagine how challenging it must be to run a clothing small business at a time when complaints are more common and likely to occur because it’s so easy to just hit send as a faceless message to the world. I not only applaud Alex’s determination to face that challenge anyway, I praise how well he demonstrated direct attention and care to my after-purchase request for help with my order. He made a promise to help and did let me know he was facing the challenge of doing inventory. He’s doing Inventory?… Yep, definitely a small business at work. I gave a friendly ping after a few days and soon after I got an awesome personal message resolving my concern and being incredibly fair and upbeat. There’s something wonderful about getting that personal touch from someone with so much on their plate trying to make a vision work and provide a superior product. These are truly the most comfortable underwear I’ve ever worn and not once have I had to do that adjustment squat or sneak a crotch shift when I’m wearing these! My wife commented how nice these underwear feel compared to her own and said she wished Krakatoa made underwear for women with this material. Even nicer, more touches occur when I’m wearing them too. Bonus! Now with such amazing validation of a small business proving that they continue to care personally for their customer, I have no interest in buying any underwear from any other source again! Thank you, Alex! You are very appreciated!

    Best I've ever had.

    I bought a pair of these on a whim along with several other popular brands just to see what was out there in the world of undergarments. Not only have a made multiple additional purchases since then, but I'm literally buying more of these to replace other brand new pairs I've bought from other brands. The feel is amazing, the look is wonderful, and I get a smile on my face whenever I get new ones.

    Perfect boxers

    There is nothing better than Krakatoa right now in my opinion. To date I believe I have purchased about 25 pairs for myself and my son. I will not wear anything else.

    Finally! Comfort.

    Over the years, I have spent untold hundreds of dollars trying to find underwear, that do what I need them to do (keep the goods from rubbing on and sticking to, the adjoining areas.)

    A no couple of weeks ago. I thought I would try one more time, and stumbled upon Krakatoa. They give you the ability, if you put ego aside, to choose underwear for your actual size. If you’re honest with yourself, you will get the most comfortable underwear you’ve ever had on your man parts. I’m absolutely thrilled with my purchase. I’ve now purchased eight pair and will indeed be buying more. Thank you.

    Are Exactly as Hoped

    So the best thing about these briefs is that you never notice them. At all. Which is exactly what you want with undergarments. Bunching up around your thighs under your jeans? Nope, legs stay in place. Seams between your thighs and jewels? Nope, thin fabric keeps everything dry with no chafing. Parts in the wrong place when you shift in your office chair? Everything stays in place and out of the way of being squished.

    Very happy with these.

    I am a larger guy (6', 280 lbs on a good day, 41"ish waist) and carry a lot of weight in my thighs. The XL fit me perfect. I sometimes do L underwear so that the waist stays in place but that is usually too tight on my legs. No such issue here! (I also ordered a size L from Krakatoa and those also work but are more snug. Will keep them for working out). The XL waist stays in place, the legs stay on my thighs but don't constrict, and the 3" pouch seems to keep everything in place well without being noticeable when wearing all day.

    Very happy someone finally seemed to get underwear right!

    Yes, you should!

    After using these regularly for a month I can say I am very satisfied with Krakatoa! I have 6 pairs now, and every single one of them looks exactly as they did when I pulled them out of their packaging.

    Aside from them being very comfortable, their construction is high quality. I can't find a loose stitch anywhere, and after multiple washes and wears there's no fading, pilling, or any signs of degradation.

    If the quality product isn't enough, their customer service is fantastic.

    Alex's weekly newsletter is also probably the only 'marketing' email I ever open.

    Best I’ve ever worn!

    I found my new boxer briefs. They have been a huge change over under armor which I have been buying for years. No more under armor, only Karkatoa from now on.

    Better than manmade

    I have been on the hunt for quality boxer that don't ride fit the boys and are sensitive enough for my skin. Well. I found them. These boxers are soo much way better than my manmade brand. So far. In comparison I have no waistband pinches no leg rolls and the seams are not cutting into my skin. The 7" leg length is perfect for my work clothes and when im lounging around the house boom nothing but boxers. My wife loves the man pouch she said its easy mood identifiers (wink wink) all in all I would rate these a 9/10. Because only God is perfect........
