What should I know about the fit?

The Pinatubo Jockstrap features a luxurious lined pouch that offers full support, complemented by sleek side straps that gently embrace your legs for optimal comfort.

The pouch is designed to be large enough to provide you ample room, while being double layered with a perforated 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.

    Softest Jock Ever!

    Avid jock wearer here. These are the softest jocks I've ever worn. The fit is comfortable and you can forget your wearing it. I'm a 5'7" 200 lb thick man. The leg straps are slightly farther back on the waistband than I'm used to with other jocks which can help keep the strap from riding up if you're worried about that. The construction feels very sturdy too. My only slight complaint is the pouch is slightly small.

    Very comfortable. I especially like the leg straps which do not seem to curl with usage. I will be interested to see how warm it is with rising temps( being a lined pouch). Waistband fit is excellent.

    Super comfortable

    I’m a heavy set guy and these fit really comfortably. They do sit quite a bit lower than my normal underwear, but they look and feel great anyway.

    Great jock strap for running. Could use a little more room but that would could defeat the purpose. Nice feeling material and looks great like the regular length trunks. Thanks for the options for different uses.

    Amazing jock!!! Highly recommended

    This was my first jock purchase from Krakatoa and it is the best jock I’ve ever worn. Same great materials and quality as expected. The straps are super comfortable and don’t roll which is awesome. The straps are also attached further back on the waistband so the straps pass over your glutes and not down under your leg which is uncomfortable in my opinion This jock fits like a sport brief/bikini (when are you making those Alex!?) with high cut legs and a bit cheeky for total freedom of movement. I bought a size small even though I am technically a medium and the fit is spot-on! I am sure I could wear a medium but I prefer a more snug fit and these are great while still having ample pouch for my package. I am going to buy the Haleakala jock next with the slightly larger pouch which I do enjoy.

    Perfect fit

    This is not your pop’s jockstrap. It fits perfectly and provides good support. The pouch is shaped for the purpose instead of being a big stretchy sack. And it looks great - for those times when someone else might notice.
