What should I know about the fit?

The Pinatubo No-Liner Jockstrap features a luxurious 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 our superb 95% MicroModal, that is more elastic than the lined pouches, for more stretch and room.

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 MicroModal 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.

    Really Comfortable Jock!

    I purchased both the lined and unlined version. I preferred the unlined version. The fit was the same on both, but personally I found the unlined one to be more comfortable. The fabric is super soft, while still being supportive for your package. A great addition to my underwear collection. Definitely recommend.

    Great Underwear

    I purchased a blue and black version, and they are very comfortable and supportive. I have used them for cardio workouts and weight training, and have been very satisfied with the quality and performance. They appear to be very well made and should stand up to rigorous use. On me they ride a bit low on the waist, but that does not affect the overall comfort. Definitely a great product.

    Owner of a company that is familiar in both in purpose and comfort.

    I have road tested all 3 styles and there each in a class of there own. I believe that 2 things can be said. Purpose and comfort have been accomplished. both in material used as well.

    Nice quality fabric!

    Feels incredibly nice on the skin, and the band is quite comfortable with minimal folding. Material is great and super-breathable. I'm more heavyset than this is probably meant for- I just barely eek in for the XL size jockstraps. The waistband fits perfectly, but honestly I could stand for the leg straps to be a bit longer to accommodate my thighs. If they offered these in a single size up or made some minor adjustments for the thigh straps, I'd definitely come back to grab a whole pack.

    Love them!

    Put Krakatoa to the test by ordering a few different styles. Happy to say, they have not disappointed. So far, everything has been high quality and very comfortable.

    One thing I will say - I was between waist sizes and sized up. Knowing how they run, I will size down in the future.

    First Pair - Great Choice

    I delayed trying out this brand, and glad I finally pulled the trigger.

    Great jock

    I don't usually wear them until I found this brand. Feels great. Straps don't pull. Things stay where they should.
