The Details

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!

How thin and flexible is the Caldera Pouch?

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.

What should I know about the fit?

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.

What if I'm in between sizes?

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.

What's MicroModal fabric?

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.

Why such a big pouch?

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.

When will my item ship? How long will it take to arrive?

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.

What is your returns and refunds policy?

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.

WE ARE UNABLE TO ACCEPT ANY PRODUCTS THAT HAVE BEEN WORN.

We strongly encourage you to add shipping insurance and hassle free returns to your orders as it appears in the cart, especially if it’s your first order.

We strongly recommend that you only try on only one pair for sizing purposes.

You can start a return at any time in our Returns Portal.

Given the nature of our product, and for health and safety reasons, we are unable to provide exchanges at this time.

Buyer will be responsible for any associated return shipping costs.

How do I wash my Krakatoa?

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.

Please do not bleach, iron, or dry clean your boxer briefs or trunks. You can also wash it by hand and lay it flat to dry, for great results.

What's your 52 Wash Guarantee?

We want you to feel confident making your purchase from us. We provide a 52 Wash Guarantee which is triggered by either 52 washes or 12 months from the date of purchase. If your item has any structural damage resulting from a manufacturer's defect before 52 washes or 12 months, we'll replace them for just the cost of shipping.

The guarantee excludes damage caused by neglect or abuse, by intentional damage, accidental damage, color fade, pilling, stains of any kind, and deliberate attempts to damage the product.

Applies to any product purchased, does not apply to any product provided as a replacement.

Send us an email at support@krakatoaunderwear.com with the subject "52 Wash Guarantee Claim". Please be sure to include photos of the damage. We will be in touch shortly after.

    Very supportive

    Very comfortable fabric. The seamless construction provides for more comfort than other models. It also is more supportive than I thought so I may be able to do some exercise in it even though the fabric is looser
