The Details

The Trunk, perfected.

Sporting the new StratoPouch, an extra-large 4" front pouch with a breathable liner, the Haleakala Trunks are the sportiest Trunk of the line up.

With a shorter inseam and ultra-low profile seamless hems, they contour around your crotch and move with you without bunching up, perfect for strenuous exercise without restrictions.

Form-fitting ultra-premium 95% MicroModal fabric holds you softly and leaves you fresh all day.

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

Legs that don't roll up or bunch up.

Inseam: 1.5 inch

52 Wash Guarantee. Because we can.

1st Order Fit Guarantee

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 work with you to make it right.

They are usually a bit more snug when brand-new, so give it a wear and a wash to reach their final shape.

If you purchase multiple pairs, make sure you ONLY TRY ON ONE PAIR and make sure it's perfect on you.

Beyond the first pair, all underwear must be unworn, unwashed, in the original condition and packaging that you received them for an exchange or refund.

52 Wash Guarantee

We've built a tough product with advanced stitching, and the very best materials we could get our hands on.

That said, you should follow the care instructions: wash it cold and dry in medium temperatures with similar soft fabrics, for best results and durability.

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 just the cost of shipping.

Free US Shipping on Orders $75+

We provide free basic shipping for all orders over $75 in the United States.

THE FINEST MICROMODAL FABRIC
Exceptional Softness and Breathability.

No synthetics here -and no PFAS.

FLAT SEAMLESS HEMS
For Legs That Stay Put.

Seamless hems are a game-changer, offering unmatched comfort and a sleek look under any outfit. Their innovative design ensures they stay put without pinching or leaving marks, providing a smooth, barely-there feel against your skin.

Experience the perfect blend of style and substance with a waistband that uplifts and empowers you.

HEY ALEX, I HAVE QUESTIONS!

What's StratoPouch?

Men come in all different shapes and sizes but for years underwear failed to respect our anatomy.
The StratoPouch is expertly crafted to provide optimal support and breathability for most men. Designed with a deeper, narrower shape and increased volume, it offers a perfect balance of separation and comfort.
Say goodbye to constant adjustments—sticking to your leg is now a thing of the past. The new internal liner is a game-changer: perforated for breathability, anti-microbial for odor resistance, and incredibly smooth to prevent any sticking, even during those happy moments.
Because it was time someone did it right for us guys.

What's the composition of the liner?

The liner inside the StratoPouch is made of 63.3% Viscose, 27.7% Polyester, 4% Nylon and 5% Spandex.

What should I know about the fit?

The Haleakala Trunk is designed with a shorter 1.5" inseam. The seamless legs are designed to stay put. The larger pouch is designed to be large enough to provide you room, while being lined for greater breathability and to also provide support and privacy for your privates. All of this is benefited by our use of MicroModal which is incredibly lightweight and breathable.

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.

INTRO PAIRS ARE FINAL SALE AND NOT RETURNABLE.

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 just the cost of shipping.

WHICH TRUNK IS BEST FOR ME?

Each Krakatoa Collection comes with a specific pouch and hem.
While they all share the same absurdly soft fabric and unflippable waistband, their pouches and hems are what set them apart.

    Amazing underwear

    I am an older, portly gentleman. If you are an older, portly gentle man and are looking for underwear that addresses the issues that affect older, portly gentlemen (which will not be enumerated here but if you are an older, portly gentlemen you know of what I speak) do not hesitate to buy this underwear. They are almost magical when compared to what you buy at your local box store. The wizards at Krakatoa figured out the right materials to use and some other worldly technique for the way they stitched the seams. It really feels like you are not wearing anything, they are that unnoticeable, and yet they do an excellent job. They are that good.

    Haleakala trunks lined

    Was unsure about lined, totally amazed with how they feel. I was at docs and was handed a pair of paper boxers because the nurse told me to take off my shorts and just leave your boxers. She thought I had nothing on under my shorts I said I did. So I had my exam and the female doc asked me what kind of boxers they were.I told her krakatoas, I explained and showed her they were the lined trunks. She was totally impressed,loved the band and material
