Our number one goal is that you're happy with your purchase.

After this first pair, all underwear must be unworn, unwashed, in the original condition and packaging you received them in for a refund.

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.

Find your size

You'll need a a pair of your existing underwear, a flat surface, and a measuring tape.

I'm Alex, I made these for you.

Every little detail was obsessively fine-tuned, to deliver you an underwear experience like no other: 

THE FEATURES YOU ASKED FOR

A POUCH FOR THE AGES
Roomy and Accessible

Your go-to Brief for daily adventures now has a fly!
With a larger 4" deep dual-ply pouch, and a handy horizontal fly, they are perfect for the gym, for when you're feeling frisky, and for any time you need quick access to the goods -while looking great in the process.

With a low hang and a lot of capacity, the pouch on the Pinatubo Brief is the perfect combination of form and function -with style.

SMALL DETAILS, BIG RESULTS
We Obsess With Your Comfort

The narrower bridge connection between the pouch and the back allows you to breathe much more effectively, and reduces bunch-ups between your legs.

THE FINEST MICROMODAL FABRIC
Exceptional Softness and Breathability.

No synthetics here -and no PFAS.

Feel softness like never before with an ultra-premium, hand selected 95% MicroModal fabric. We source only the best MicroModal because comfort is our #1 goal. (Learn about MicroModal). We just add 5% of Spandex to allow for it to move with you.

We never skimp on the quality of our fabrics and materials, neither on the craftsmanship. These products go on your softest, most sensitive parts. We won't settle for anything less than the very best.

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 is what set them apart.
Here is a quick guide:

HEY ALEX, I HAVE QUESTIONS!

What should I know about the fit?

The Anti-Gravity Brief does not have an inseam and the fabric between the legs is 40% narrower for an all day comfortable feel that won't bunch up. The pouch is designed to be large enough to provide you room, while being double layered to also provide support and privacy for your privates. All of this is benefited by our use of MicroModal which is incredibly lightweight and breathable.

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.

    These are amazing, as are all the Krakatoa products! So incredibly comfortable. I love how the pouch is formed, and the square cut is perfect.

    Smoth as frog hair

    The smoothest most comfortable underwear made. No more chafing no more sweating. These bulge enhancing comfortable draws are the best.

    Amazing

    Love these briefs! Fit is great and they truly feel like you’re not wearing underwear. The pouch keeps the junk together nicely, slightly transparent depending on the lighting, which I like. I’m definitely a fan now!
