I'm Alex, I made these for you.

FULL SUPPORT WITH A FLY Putting the Fun in Functional

Pinatubo’s 3” deep pouch design with minimal stitching keeps you comfortable and secure all day.
The one-handed, top-access horizontal fly provides effortless reach into the goods.
The low-stitching 3" pouch is ultra-smooth, without holes, panels or gimmicks.
It just works.
It separates you from your thighs, ensuring comfortable support through all of life’s adventures.

THE FINEST MICROMODAL FABRIC
Exceptional Softness and Breathability.

Say goodbye to readjustments!
Our large 3" pouch design with minimal stitching ensures you stay comfortable and secure all day.

The one-handed easy-to-use horizontal fly allows for easy access.

It separates you from your thighs and keeps you comfortably supported in all of life's adventures.

SOFT STITCH HEMS
For Legs That Stay Put.

Our boxer briefs are perfect for active guys that prefer a longer leg to fit under their pants or long shorts. They are ideal for daily wear, hiking and protecting the inner thighs from chafing.

The legs are cut to be tailored but not compression. The bottom hems are stitched to stay in place, the longer legs allow for the legs to stay put and not ride up over the quad. 

UNFLIPPABLE WAISTBAND
Art On Your Body.

Our waistbands are wide, smooth, don't leave marks, and are truly unflippable, offering a secure fit that prioritizes style and your comfort over branding. We focus on modern designs rather than flashy logos, framing your body beautifully.

Inside, you’ll find positive, self-affirming words designed to motivate you daily, inspiring you to be a better person to yourself, and to those around you.

Experience the perfect blend of style and substance with a waistband that uplifts and empowers you.

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.

    Perfect Fit and Unmatched Comfort

    I recently purchased these boxer briefs and couldn't be more satisfied. They offer a perfect fit without any binding, ensuring comfort throughout the day. The fabric is incredibly breathable and light, keeping me cool and comfortable no matter the weather. The waistband is smooth and stays in place without folding over, which is a big plus. Additionally, the roomy pouch with an easy-access fly adds to the convenience and comfort. These are my new favorite boxers. Highly recommended!

    As advertised!!

    Wow! Never had more comfortable underwear, ever! As a man, I love the front opening to be able to flip right out and pee with ease. I’ll be buying more for sure, and will be throwing away a bunch as well. No, I do not work for the company. I am an unbiased actual customer

    Great product!

    I have wore UnderArmour boxer briefs for the last 15 years and recently made the switch. I can’t believe how soft and silky smooth and comfortable these boxer briefs are. You should order the trial pair and I’m sure you’ll be convinced just as I am.

    Happy Customer!

    I saw an add one day on Instagram that convinced me to try a pair of these underwear so I did. I was so happy with them I immediately went to their website and bought more. In my humble opinion they are the most comfortable underwear I’ve ever worn.

    Rather Nice & Comfortable

    I greatly appreciate the style, design,and materials used in the garment.

    My only downside to the purchase is that for whatever reason I thought it was a triple pack. Imagine my surprise when I received only unit.

    Accordingly, the unit cost is very high in my opinion.

    Nonetheless, it is worth it if you can afford it of course.
