Supreme Support With Style to Boot

With a large, 3" deep pouch with a perforated liner for better breathability, the Haleakala Thong's pouch is also naturally non-stick (*wink, wink*), and will keep you supported, in style.

Form-fitting ultra-premium MicroModal fabric wraps the pouch, for a super soft touch all around.
The thin and foldable back string has a low profile that you will barely feel.

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

52 Wash Guarantee.
Because we can.

Find your size

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


The Haleakala Thongs are perfect for active guys that prefer maximum support and a stealthy profile. With a large front pouch with an anti-microbial and breathable internal liner that is also non-stick, to avoid any Velcro-moments when you have some DNA leakage, they will be your go-to adventure partner from the gym to the club.

The back strap has a thin parallel stitching that can be folded for an even slimmer profile, for maximum comfort.

Need a little more coverage? Check our our Briefs or Trunks for a more enveloping wrap.

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


  • Feel softness like never before with an ultra-premium, hand selected 95% MicroModal fabric. We source only the best MicroModal because comfort is our #1 goal. (Learn about MicroModal). We then blend the MicroModal with 5% Spandex to allow for it to move with you.
  • Enjoy more room with a large front pouch that provides space and support for your cargo, with complete separation from your thighs. No need to adjust anymore.
  • Feel comfortable all day with a waistband that doesn't flip or fold.
  • And keep them longer with the peace of mind of our 52 Wash Guarantee.


The Haleakala Thongs are specifically designed for maximum comfort in a minimalist approach. They work well for a variety of activities, from working out to dancing or practicing sports, they can take on anything you throw at them. Once you make the decision to embrace this everyday luxury for your privates, getting dressed in the morning will never be the same again.

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


What should I know about the fit?

The Haleakala 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.


    Haleakala's StratoPouch is roomier, deeper, more breathable and with a perforated liner that will make even hot summer days a breeze. It's odor resistant, it separates and cradles you like never before, and it's also naturally non-stick, for when we have DNA leaks during happy times.


    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.

    Try one and see!

    Never considered myself a thong kinda guy. I've used boxer briefs for 25 years or so, and boxers before that.....why change now? I've tried two thong brands other than these in my 40+ years.,.... String too thick, or pouch too small, never a good fit....wrote them off.

    But then I found Krakatoa, and tried the 10 dollar boxer brief. Impressed I came back to order more, at which point i figured what the hell, and threw a thong in my cart too.

    These are awesome. Supremely comfortable, double layer pouch with great support, holds the goods without any gaps. String is comfortable enough to wear them all day, so much so I almost forget I'm wearing them. Some of my pants fit tight enough (chino/dress/leggings) where underwear lines ruin the look from behind, or feel bulky. No worries with these.

    My wife wasn't too keen on the idea of her man in a thong.......till I she saw me in one. She's now sold.

    Be brave, try one. Its worth it.

    This just became the best thong in my drawer! Too many seem to just “be a shape” instead of “become a shape.” They’re so much softer than the rest, and the lining is 11/10. Perfectly executed.

    Doesn’t feel like anything.

    I have a “sit on my ass all day” job and randomly tried one of these out. I like that I’m not sitting on underwear seams. This one has a good pouch and a comfortable thong. I’ve workout out in them and they’ve kept me cool, especially on run day and leg day. Wife loves them, haha. She was slightly surprised at first but loves the look.

    Most Comfortable Underwear

    These are the most comfortable underwear I have ever worn. They are definitely the first I pick out to wear if clean. Feels like you are wearing nothing.

    Fun and weird

    Excellent material, band is perfect and doesn’t roll or chaff. Soft, cooling, and comfy. A little snug, I’ll get one size up next time.
