Form-fitting ultra-premium 95% MicroModal fabric holds you softly and leaves you fresh all day.

Wide and ultra-smooth waistband won't flip or mark your skin.

HEY ALEX, I HAVE QUESTIONS!

What's the Caldera Pouch?

Our new Caldera Pouch is a reimagined front pouch, featuring a U-shape design that offers a natural feel and relaxed support.
It's not designed for vigorous activities, because it's like you are Going Commando, but without sticking to your legs.
The innovative design gently cradles your genitals, allowing them to naturally fall into place for a super comfortable and natural fit.
Crafted from a single layer of our ultra-thin 95% MicroModal fabric, the Caldera Pouch offers a barely-there sensation while providing all-day comfort and breathability.

What should I know about the fit?

The Vesuvius Next Gen Brief is designed with seamless hems on the leg openings for a stealthy look and supreme comfort, besides staying put all day.

The Caldera Pouch is designed to be large enough to provide you a lot of elasticity and room, while being single-layered to provide you with an incredibly natural feeling. All the hang, none of the sticking.

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.

WHICH BRIEF IS BEST FOR ME?

Each Krakatoa Collection comes with a specific pouch and hem.
While they all share the same absurdly soft fabric and unflippable waistband, their pouches and hems are what set them apart.

    Very comfortable, especially for a man my size. Eye catching and appealing. Love them. When I buy others, they'll be these.

    Very Comfortable

    I wasn't sure how I would like the fly and if it would make them fit weird, but they fit great and the fly is very nice to have. Sometimes you just don't want the fly so I have ones without as well, but the two pairs of these will definitely be in the rotation.

    Very comfortable briefs !

    I must say, these are very, very comfortable briefs. The leg bands are extra special--very thin and almost unnoticeable. Fabric is so soft.

    Great fit!

    This company is so great to work with. Customer service is excellent. I have purchased about 10 pair. I usually don’t wear briefs but thought I would try. Super comfortable, no bunching up, my boys comfortably are held in place. No sweating or adjusting and no stench. Thanks for a great fit.

    Service above and beyond, and excellent products to boot!!

    I own half a dozen Krakatoa products and really like them all, but the Vesuvius briefs are probably my favorites. I have a largish package that needs to be stowed comfortably, and the Vesuvius briefs accomplish this task with aplomb. These briefs are so comfortable that I don't know I'm wearing them. A little about my physique: I'm a cyclist with big thighs but a small waist. All my Krakatoa products are size small; I'm 5'11" and weigh 153 lbs. Don't hesitate to pull the trigger on these briefs. You won't be disappointed!!

    The advertising is true

    Most brands advertise as having a roomy pouch but lacks that. The Krakatoa’s Vesuvius briefs have an average size anatomical pocket that you can easily slide into and conforms to your shape. If you’re well endowed they will stretch out without feeling restricted due to the micro modal and spandex material. If you like snug fitting briefs these Vesuvius briefs are not for you. The pouch gives you a free hang loose feeling, but you’re still supported. In regards to the waistband it was true that it does not roll over. I think the waistband was purposely made slightly bigger to keep the band in place, and although you might feel the band at first its not too tight and you get use to it. Also when it comes to briefs with most brands it gives a wedgie because there’s not enough fabric on the rear or it rides up the rear. The Krakatoa’s are wedgie free. Another plus for me, I like how the pouch hangs down rather than try to lift your equipment forward like how other brands do. The forward lift with other brands will show the outline of your bulge under shorts. With the Krakatoa’s Vesuvius briefs I can wear gym shorts comfortably over them without showing an outline of my bulge. Because the outline of the briefs don’t show under your pants these can be your everyday underwear you wear to work, gym, or family events. If I’m nitpicking here, the only thing i did not like was the design and colors on the waistband. But the waistband, fit, functionality, and comfort are all top notch.…
