What should I know about the fit?

The Pinatubo Thong 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.

    Upped to 5 star!

    Originally i gave these 4 stars because I was expecting a single later pouch. But now that I have worn them, I love them! I have bought about 8 more! Love the fit. The pouch is supportive, soft and not restrictive at all. The thong strap is very comfortable. The waist band stays put all day. Ordering more of the new colors!

    Awesome Pinatubo thong!

    This is my first KRAKATOA purchase and I opted for the thong because that is my favorite out of all their available styles. If they made a sport brief version I would have purchased that too so I am hopeful that will the next new product.

    For starters, my biggest concern with a new underwear brand is figuring out the sizing because despite what the size guide says, a medium in one brand might be smaller or larger in another. I am 6-1 170# and can usually wear a small or medium so I opted for a small in the Pinatubo thong and I am glad that I did. The waistband and material are both sufficiently stretchy and the KRAKATOA small is 31-33” so the fit is perfect! A medium would fit like a large and I am definitely NOT large. The pouch design is a bit wider than I prefer but the 2-layer pouch is very comfortable and accomodating to my package. The tapered thong back is super-comfortable and disappears between the cheeks as described. The soft material feels amazing while wearing and the rear is sized perfectly so the thong can worn lower on the hips or a bit higher while having the right amount of tension on the pouch to keep everything securely in place. I’ve worn my new thong hiking on a couple occasions and it was perfect for these types of activities; no adjusting, no chafing, just perfect support and fit the whole time. I highly recommend this product and look forward to buying more thongs and HOPEFULLY a sport brief when that becomes available.

    Best pair I own

    I’m new to wearing thongs. I’ve tried a few different brands and by far this is the best thong. I started wearing thongs to workout in for max support and this does it. It feels like you’re wearing nothing at times. The string is comfortable. Only complaint is I’m an 34” waist and the size ranges from a 34”-37” so they are on the verge of being too big. Also I could do without the words on the inside. Overall a great product.
