The Thong Supreme

With the elastic, ultra-thin, single-ply Caldera Pouch, and its seamless hems and string, the Vesuvius Seamless Thong offers the most natural feel in the entire lineup.

It provides minimal lift, allowing you to hang naturally and experience everything that touches it.

The paper-thin seamless string at the back has the smallest footprint of any Krakatoa Thong, making it almost imperceptible.

A single ply of form-fitting, ultra-premium MicroModal fabric wraps the drop-down pouch, delivering an incredibly soft touch all around.

HEY ALEX, I HAVE QUESTIONS!

The Caldera Pouch is single-ply, as elastic as the fabric allows, and incredibly sensitive to the touch -enhancing your experience whether alone or with company.

The Vesuvius Seamless Thong has an ultra-thin pouch to separate you from your legs, and give you the utmost freedom in underwear. The drop-down design of the Caldera Pouch provides no lift, but it's the most natural feeling of all Krakatoa pouches. It's the closest thing to Going Commando, so you can let it all hang -in comfort.

Our sizes run pretty true and the materials do have stretch to them.

But if you're not sure which size is going to be the best for you, consider these three things:- Your waist in inches (pants size is OK).

- If your legs touch at the thighs.
- If you have a small, normal or large butt.

If your legs touch and your butt is large, you might jump a size.

If you have a small butt and thin legs, you can downsize.

In a word. Soft.

Really soft, our MicroModal is hand-selected to be of the highest grade available.

MicroModal is a modern technical fabric that is manufactured with cellulose from renewable Beechwood trees. Compared with Cotton, it's odor-resistant, 3 times softer, 50% more breathable, and it's not nearly as polluting or water-wasting.

Men come in all different shapes and sizes but for years underwear failed to respect our anatomy.

Our pouch is designed for the majority of men out there to accommodate and coddle. It's a blend of being soft with some stretch where needed, but also supportive for all day comfort. You won't need to adjust yourself anymore, because sticking to your legs is a thing of the past.

Please allow 2-4 days for processing, and the usual shipping times from the USPS or UPS: inside the US you can expect to see your package between 3-6 days.

We'll send you a confirmation email with your tracking information as soon as it ships.

If you have any questions or don't receive an email, feel free to reach out via our Contact Us Page.

All returns are available for 60 days following their delivery date.

We’re happy to accept any items that are unused, unopened, unworn, and in their original packaging.

Krakatoa is quite resistant to shrinking and fading, but machine-washing them in cold water using the delicate setting and drying in low heat will keep them looking fresher for longer.

    Next to naked

    Besides the obvious lack of coverage, these really do feel like there's nothing there. I was worried that the pouch may be a bit too extra, but in fact, it gives just enough support and the single layer of fabric affords nice wiggle room and breathability. Great for hot climates like S. Florida.

    1st Thong - It Is AMAZING!

    I’m starting to wear more form fitting clothes these days and needed something more “no-show” and this pair delivered! Not only that, it is terrific for the gym when you need a little extra air flow during those tough workouts. The textile is so incredibly buttery soft and feels insanely comfortable. I really do love the seamlessness of the design, super nice. The star of the show is the pouch - your package falls perfect into the well thought-out pouch, and makes you look and feel huge. Instant boost of confidence! Honesty, I want to buy more colors. Another 10/10 from Alex and the Krakatoa team. Zero hesitation recommending this thong!

    Wow, Impressed and very much what' I've been looking for!

    Yup, they're as good as they sound and what everyone says about them. Excellent construction, top quality fabrics and materials, perfect fit. Normally, a thong could be seen as uncomfortable, but this is the complete opposite. Highly recommend and make it a daily wear. Your good will definitely be thanking you!

    My New Favorite Thong!

    I own all the Krakatoa thong styles as well as several other brands of thongs. Krakatoa are by far the best quality, best fit and most comfortable of all the brands I have tried. The Vesuvius thong makes a great thing even better. The material is super soft and feels so thin which makes them incredibly comfortable. The Vesuvius thong has an amazing pouch which makes them super easy to put on with no adjusting needed like with other thong pouches. If you have never tried a thong, do it! You will not regret it, especially the Krakatoa brand. Extra bonus is that my wife loves the way I look in them too!

    MOST COMFORTABLE MEN'S THONG

    Why did I wait?

    I have purchased several Krakatoa thongs. AND a few from other brands. I came to wear the thong style as opposed to commando as the twins were not happy bouncing and chafing about. I’m old. Retired at 70 four years ago after being in my career for 5 decades. First thing I did was pitch my traditional underwear. Ergo hello Krakatoa! The differences between Krakatoa and the cheaper brands are numerous and significant. Quality of manufacture, style and design with significant attention to male fit and feel and a true attention to detail. Thanks Krakatoa!!

    First time trying thong. Perfect!!!!

    This is my first time trying a thong. I received this complementy to try and review. I was blown away by how comfortable it actually is to wear and the material feels great. I will definitely think about purchasing another. I already have a pair of brief and trunk style which I also enjoy. Thank you

    New Vesuvius T is Favorite

    I've tried just about every style, and the new Vesuvious Seamless Thong is my favorite. I wear it running and at the gym and it's perfect for support, comfort and the new material is so amazingly improved. I need more colors as this will be my everyday go--to. The green is perfect, but the blue is too bright Hoping for black, dark red, dark purple and dark blue. Great job team!

    Nailed it!

    Fantastic fitting pouch. Tried the other versions and didn’t quite work for me. This pouch is the biggest Krakatoa has I believe. I am happy that there is finally a pouch to hold the jewels that stretch’s and doesn’t pull away leaving skin on skin irritation. The other Krakatoa trunks and briefs solve that problem and now there is a thong that does it too! Excellent work!!!!

    This thong is the best!

    I was super glad I was able to get to try the new Vesuvius thong and it is by far the most comfortable thong I own! I will say the fabric is so soft so it feels great and doesn’t chafe or feel uncomfortable after a long day of work or exercise
