HEY ALEX, I HAVE QUESTIONS!

What should I know about the fit?

The Pinatubo Boxer Brief is designed with a 7" inseam.
The legs are designed to stay put, but be long enough to cover an increased amount of your legs to add a layer of protection from friction.
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.
The Horizontal Fly allows for super easy access.
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 or medium temperature water, 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.

WHICH BOXER 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.

    Great for guys who aren't packing much!!

    They feel comfortable and the legs don't seem to ride up very much. I'm very happy with the support it offers and it cradles everything. Even if you have a small penis these underwear make it look great unlike other pairs on here. 10/10

    Size change

    I recently purchased Krakatoa underwear and had an outstanding experience, both with the product and the customer service. The quality of the underwear is top notch, and attention to detail that other companies just don’t have. My initial impression was “where have these underwear been my whole life?” Which faded pretty quickly when they started to ride up and cause just the slightest wedgie, not bad just enough to annoy the shit out of you. I had already made a full second order after how much I liked them at first. So I took a shot in the dark, and sent an email asking if they’d change the sizes on my whole order. Alex did that, and then some!

    Thats real reason I’m writing this, is the exceptional customer service I received. I had sent an email over asking if they’d change the sizes on my order (last minute). Alex responded promptly, ensured the correct size was updated, and my order was on the way. He even took the time to check in and ask if I was happy with the new size!

    I can’t recommend Krakatoa underwear enough! Not just for its superior quality, but also for the outstanding customer care. If anyone had told me the owner/ ceo of a company would email me to make sure I was satisfied with my order i would have thought they were crazy, but here we are.

    Couldn’t recommend Krakatoa enough! I’m already planning my next order. As long as Krakatoa is in the underwear game, they’ll have my business.

    Cradle the jewels with comfort

    Most comfortable boxer briefs I've ever worn. Horizontal fly is a huge improvement over typical vertical fly for easy access & no accidental display, waistband incredibly comfy & doesn't roll, fabric & breathability A+.

    GAME CHANGER!

    These are officially my new favorite underwear! The "Kangaroo pouch" opening is a game changer—way more practical and comfortable than the traditional fly design. The material is top-notch: super soft, breathable, and it stays comfortable all day. Highly recommend if you're looking to upgrade your underwear game.

    These are great, I can't wait to purchase more next month

    They fit perfectly, no thigh rub, easy to use pouch flap.

    They are pricey, but I will slowly buy more over time.

    Holds everything in place

    Work a lot of time in summer heat. Have gone commando for years, just out of comfort and not having to constantly adjust. Gotten to point where wife complaining about thing showing through jeans too much. Tried other "pouch" brands and they did nothing to support. These Krakatoa keep everything loaded in right spot and no more adjusting and still unsure if wife happy or not. She likes the look in private but now everything in place still shows more than she'd prefer.
