The Details

The Pinatubo Brief with a horizontal fly, with an extra roomy pouch, is the Brief you were looking for.

An extra-deep front pouch with a super slick horizontal fly, that was engineered for easy access and excellent comfort, will keep you supported without fuss.

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

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

40% less material between the legs.

52 Wash Guarantee. Because we can.

1st Order Fit Guarantee

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

If something doesn't fit right on your regular priced Krakatoa, let us know and we will work with you to make it right.

They are usually a bit more snug when brand-new, so give it a wear and a wash to reach their final shape.

If you purchase multiple pairs, make sure you ONLY TRY ON ONE PAIR and make sure it's perfect on you.

Beyond the first pair, all underwear must be unworn, unwashed, in the original condition and packaging that you received them for an exchange or refund.

52 Wash Guarantee

We've built a tough product with advanced stitching, and the very best materials we could get our hands on.

That said, you should follow the care instructions: wash it cold and dry in medium temperatures with similar soft fabrics, for best results and durability.

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 before 52 washes or 12 months, we'll replace them for just the cost of shipping.

Free US Shipping on Orders $75+

We provide free basic shipping for all orders over $75 in the United States.

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?

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

If something doesn't fit right on your regular priced Krakatoa, let us know and we will make it right.

Try on a pair and make sure it's perfect in you. If it doesn't work for you, your first regular priced pair is covered.

After this first pair, all underwear must be unworn, unwashed, in the original condition and packaging that you received them for a refund.
If you bought multiple pairs, make sure you try ONLY ONE PAIR for fitting before you decide to use the rest.

INTRO PAIRS ARE FINAL SALE AND NOT RETURNABLE.

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've built a tough product with reinforced stitching that lays flat and the very best materials we could get our hands on.

That said, you should follow the care instructions.

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 before 52 washes or 12 months, we'll replace them for free.

    Best Briefs I have ever owned

    As someone with a implant due to medical issues it has always been very difficult wearing regular inexpensive cotton briefs. There is not enough room for me. I slip out of the briefs, always adjusting, tucking myself back in, etc.

    Your briefs are amazing. I have enough room with the pouch. I also really like how they cup me all the way up to the top of my legs, keeping me in the pouch all day. They are very comfortable whether I am at the gym or just lounging around. I aslo wear them when I al sleeping to keep everything all tucked in. I don't even feel like I am wearing anything.

    Thank you for developing these and keep up the good work. I ordered 4 to try them out...loved them so I ordered 8 more. I will be purchasing more next month just to have on hand.

    BEST. BRIEFS . EVER !!!!!

    For some reason no one wears briefs anymore making the selection out there much smaller these days. I’ve been hunting for the perfect NEW brief for me as a 5’7” 250 pound big guy . My regular big name brand I always wore stopped making my favorite brief. Did a LOT of inet research some chat rooms and read reviews and discovered this amazing brand KRAKATOA!!! Game changer; not just the most comfortable breathable non constricting (but still some control ) modal material ; but the pouch is roomy too, but the big win , its hard to find a thick waistband that doesn’t FLIP /double over your belly if youve got a bit belly , not only do these briefs check all the boxes- BUT BONUS BENEFIT -NO PANTY LINES! I never noticed until I tried these Krakatoa briefs that ALL my other briefs give me a visible “panty line” you can see the outline of my briefs through my pants! Happy to find my new favorite classic brief had a “glow up” and is now updated for the modern man. I’m ordering 20 now!!!

    Best briefs ever!

    Finally, underwear designed by a man for men. No more parts escaping when I slide off my car seat, as the well designed pouch keeps it together. I purchased one to try. Three days later ordered seven more. Thank you for the great design!

    Comfort

    The pouch is great! Very comfortable underwear. Smaller area of fabric between the legs is much better. Why hasn't someone thought of this before. Recommended

    Good fit and super soft

    I really enjoy these briefs. I normally wear trunks of boxer briefs, but decided to try something different and glad I did. They do sit a little lower on my hips than I am used to, but I love the feel and the fit.
