Hello to our supporting cast member!

A large lined pouch for better breathability.

Large, 3" deep front pouch engineered to separate you from your thighs and keep you comfortably supported.

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.

52 Wash Guarantee. Because we can.


The Pinatubo Jockstraps are perfect for active guys that prefer maximum support and nothing else. With a large front pouch with an anti-microbial and breathable internal liner that is also non-stick, they will be your partners in any adventures you put them through.

Whether you're working out or going for a night out, these Jockstraps are so comfortable you'll forget you're wearing them.


With wide side-straps covered with our ultra-premium 95% MicroModal fabric, their buttery feel will make you forget they are there.The butterfly-style connection to the large pouch folds between your legs and you barely feel them.

Our exclusive waistband never flips and stays put, without marking or pinching your skin.

The internal liner puts them in a class of their own.

We believe they will be the best Jockstrap you ever wear.


The Pinatubo Jockstraps have an oversized pouch with an internal perforated liner that is also anti-microbial, and feels like a soft nest. With the mesh it increases breathability to allow for more airflow, keeping you cool all day long.

They work well for a variety of activities, from working out to making out, they can take on anything you throw at them. Once you make the decision to embrace this Everyday Luxury for your privates, getting dressed to go out will never be the same again. The Pinatubo Jockstrap is designed with your utmost comfort in mind.

Great for: Running, Exercising, Summer Sports, Getting Frisky.


What should I know about the fit?

The Pinatubo Jockstrap is a luxury pouch to give you perfect support without excessive fabric.

The pouch is designed to be large enough to provide you ample room, while being double layered with an internal liner that is breathable and anti-microbial, besides being non-stick, for when "DNA leakage" happens.

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.


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.


    Your skin never felt a fabric so soft and welcoming before. Three times softer than cotton, our high-grade, environmentally-conscious MicroModal fabric will make you rethink cotton and synthetics forever.


    Large, round, and deep support, without uncomfortable lift. Naturally odor resistant, it separates and cradles you, so you won't need to adjust anymore. Its double-panel construction keeps your privates more private.


    Smooth and soft to the touch, the unflippable waistband won't mark your skin and keep you comfortable all day. To complement the art outside the waistband, its interior has positive affirmations to get you going at every break.

    My boys are in heaven

    Love this jock. Makes me feel sexy and better yet supports my assets and my net worth with comfort and pleasure. I wear jocks and jock briefs as my primary underwear and I will definitely be ordering more Krakatoa products.

    Soft fabric, comfortable fit

    First thing out of the package you will notice the soft fabric. The jock stayed in place all day. The straps hug your ass without being too tight or too loose. It fit true to size. I’d recommend giving them a try.
