The Details

The Easy-Access Boxer Brief

Pinatubo’s top-access horizontal fly offers a quick-draw, one-handed action, making it easy to reach in and go—putting the ‘fun’ back in functional.
The large, 3-inch deep front pouch, with minimal stitching, is designed to keep you separated from your thighs and comfortably supported all day long.

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

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

Legs that don't roll up or bunch up.

Inseam: 7 inches

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.

I'm Alex, I made these for you.

Find your size

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

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?

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 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'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 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.

    High quality, super comfy, I found my favorite underwear!

    I recently went in search of a new go-to brand for underwear and ended up ordering from multiple shops. Krakatoa ended up being my favorites by far. They are super soft, don't ride up, and feel like they are going to last longer then some similarly priced brands. I highly recommend these!

    Bought a pair for my husband to try them, and they are the most comfortable boxer briefs he has ever owned. Ended up buying 7 more pairs.

    Great

    I really like these boxer briefs. I bought a pair of 4-5 different brands, and these were the clear winner, so I bought nine more pairs. Great colors, the waist band actually stays up, and I love the inside of the waistband. Well done, Krakatoa!

    Great Boxer Briefs

    I bought one pair for the special price of $10.00 back about 9 months ago. I liked the pouch and the material, and loved the waistband. Had some trouble mastering the higher fly. I liked them but thought the price was too high. Flash back to a two weeks ago, I decided I was not happy with the Nike boxer briefs, I also bought around 9 months ago. The waistband wasn’t comfortable, the traditional fly was also uncomfortable and material had stretched out. Then I came to the decision that the Krakatoa underwear was still brand new, after wearing them also for 9 months. I decided to go with 7 pairs, because I’m worth it. And I’ll master the higher fly, in the next few weeks.

    The best I've found

    These (and the Anti-Gravitys) are hands-down the best-fitting boxer briefs I've ever tried. Just perfect in every way -- support, cut, fabric and durability. They're snug and gently supportive but not constricting at all. The pairs in my first order a few years ago are showing some wear, sure, but still very much in the daily rotation. An outstanding product and well worth the investment.

    Amazing Comfort

    I LOVE the Pinatubo Boxer Briefs. As a man with larger low hangers, these boxer briefs offer unblievable comfiort. Tired of not having enough room? Then these are for you. Not all men are created equal.Not all undweware are created equal. thankfully! I appreciate the opening to get access when I need it. I hate the idea of pulling down the wasteband in order to take piss. If you like to sit and piss, then perhaps you won't mind. But I rather stand. The material is lightweight and the legs stay in place all day. No more needing to adjust myself several times a day. Thank you for making the Pinatubo Boxer Briefs.

    Purchased two pairs. Just what i was looking for in boxer briefs - Long leg and great support , eliminates uncomfortable chafing , leg sticking, bouncing, and the waistband does not fold over.
