    Phenomenal for active dads in the gym and on the go

    dude these are the most insanely comfortable boxer briefs I’ve ever worn. I lift 5-6 days a week, run about 10-15 miles a week and have two kids running around constantly. Just an incredible product overall. And I’ve tried Rhone, Lulu, saxx etc.

    The pouch actually allows for the space I need, and I’m always finding boxer briefs to be way too tight especially when I’m training. I am bigger below the belt and I finally found boxers that don’t hug the family jewels so tight and don’t ride up when running.

    As a dad and busy husband / full time worker, thank you for these. I definitely need to order more.

    Very comfortable and practical boxer!

    I purchased one Vesuvius boxer briefs in blue several months ago and used them before I decided to purchase more. After wearing the boxer briefs for work and hiking, I knew these are the one. The fabric is like your second skin and feels very soft. I am prone to shafting while hiking 15-20 miles but not with the Vesuvius Boxer Briefs. I ordered three more of these in black, grey and blue and they arrived promptly. They are shipped in a nice package and the presentation us appealing. I have not noticed any shrinkage on the fabric after multiple washing. The fabric is very breathable and warm even when the temperature drops. I hiked recently and summited Telescope Peak near Death Valley on March, 1st and the elevation was over 11,000 feet on top. The Vesuvious Boxers kept me warm the entire way through snow and windy conditions. I recommend these boxer boxers to my friends and family.

    Vesuvius briefs

    Quality superb, material exceptional, horizontal fly is an awesome feature. My only complaint is that I ordered XS because my waist is 29-30 but they are just a tad too small. Next sale though I will definitely buy more. The ball pouch is the best feature, especially for an active lifestyle. Thanks for a good product.

    These are amazing!

    I had only one pair of proper pouch boxer briefs before. I tried a few brands and was not impressed, but these are so comfortable AND they have a fly! Probably the best pair of underwear I've ever had!

    Never had such comfort

    This is my first time buying Krakatoas and, honestly, I’ve never had such comfortable underwear. The feel is incredibly smooth—it’s like having a thousand soft hands holding my butt and thighs and jewels. And damn—I’ve never had a pouch that kept my C & Bs surrounded by soft and lifted away from my body. I usually forget I’m wearing them but now and then when I move I’m reminded of how comfortable they’ve make my jewels feel—no need to adjust myself so everything’s in the right place; it just always is. it’s almost better than wearing nothing, but nothing beats that, though when I’m dressed I need to wear underwear—I know some guys love commando but I dislike the rough fabric of jeans against my jewels and prefer the support of boxers for my active life.

    I got a set of boxer briefs—and one brief, which I’ll write a review of the briefs separately. The boxers are for everyday wear in the cold News England winter that is coming, and I also wear them at the gym under my gym shorts-I like how the bottom of the boxers peek out when I’m doing an exercise that makes my gym shorts rise up. Yeah, they offer good support for the gym and for the active life I lead.

    Oh, and Alex offered me amazing customer service. I wasn’t sure which pouch to go with and he talked me through the issues and best fit for me. There’s nothing you can’t talk with Alex about, and his passion for his product is remarkable. Alex goes beyond customer service; it’s like concierge service. Thanks Alex.

    I…

    Only brand I’ll use

    I purchased a large mixed bundle a while back and have absolutely loved them! I’m already planning to replace every single pair in my drawer until Krakatoa is all I own. The pouch is snug, supportive, and really keeps everything out from between my legs… finally, a company that figured the pouch out!

    And as great as the product is on its own, their customer service might be even better. When one pair out of ten ripped, I reached out not expecting much at all but they responded immediately and went above and beyond!! Too many companies these days do the bare minimum, but not Krakatoa! They’ve DEFINITELY earned me as a loyal customer for the long run.

    Fervent convert

    These boxer briefs gently cup your cock and balls completly prevent all and any chafing between the upper thighs. I had found another brand that I thought achieved that goal, but Krakatoa boxer briefs do it better, with fewer seams, better and more breathable fabric -- and with a fly! I read reviews in which guys said that, although they were wearing the krakatoa boxer briefs, it still felt like going commando. I don't understand how Krakatoa does it, and I entirely agree with that description. It really does feel like going commando! Because of issues with bad chafing, I haven't been able to go commando for years and i miss it. This product has made it possible to experience that sensation again -- an unexpected benefit. So yes: a fervent convert to Krakatoa. I'll be buying more!

    Prevents ball crushing.

    Great pouch…when sitting down or driving the pouch envelops your keeps the balls cool and supported and keeps them from sliding down between the thighs and getting crushed. I have several other brands with hammocks, bullpens and sacks, but these are by far the best. And if you haven’t tried the horizontal fly, wow, you won’t go back to struggling with a vertical fly ever again. Buy one, try one….you’ll be buying more.

    Love the boxers

    I have tried many different brands/styles of boxers and these are at the top of my favorite list. They are comfortable, don't ride up and as a senior with a little belly (33" waist), I love that the waistband does not roll!

    I originally purchased a medium (in photo) and by mistake purchased large on the next order of two pair. They are fine, but the medium pair fit best. Just ordered two additional pair in medium! Thank you
