HEY ALEX, I HAVE QUESTIONS!

What's StratoPouch?

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.

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 Sports Boxer is designed with a 5" inseam. The hems on the leg openings are seamless, for a stealthy look and supreme comfort, besides staying put. They are long enough to cover an increased amount of your legs to add a layer of protection from friction. The StratoPouch is designed to be large enough to provide you room, while being double layered to also provide support and privacy for your privates.

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?

All returns are available for 60 days following their delivery date.

We’re happy to accept any items that are unused, unopened, unworn, and in their original packaging.

WE ARE UNABLE TO ACCEPT ANY PRODUCTS THAT HAVE BEEN WORN.

We strongly encourage you to add shipping insurance and hassle free returns to your orders as it appears in the cart, especially if it’s your first order.

We strongly recommend that you only try on only one pair for sizing purposes.

You can start a return at any time in our Returns Portal.

Given the nature of our product, and for health and safety reasons, we are unable to provide exchanges at this time.

Buyer will be responsible for any associated return shipping costs.

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 want you to feel confident making your purchase from us. We provide a 52 Wash Guarantee which is triggered by either 52 washes or 12 months from the date of purchase.

WHICH SPORTS BOXER 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.

    I think I found “the one”!

    These fit and feel GREAT! I have been searching for the right pair of boxer briefs for a WHILE and have tried at least four other companies, all of which where “ok” but not perfect. Krakatoa seems to have the magic formula! The pouch is supper supportive, the waist band does not roll, and it feels like I’m wearing nothing at all! Excited to order my next pair!

    Truly innovative design plus exceptional comfort!

    I saw an ad for this product and because we live in a very hot and humid climate, I thought it would be a great product for my sons….so yes weirdly enough I gifted them pairs. I got them two different designs but they preferred this one. They loved them so much that I had buy extra ‘gifts’ (additional pairs) 😊 and they are tossing out their Calvin's!

    First, but certainly not the last.

    Bought the Haleakala for the steamy summers here in Florida. The “shower” in me loves them and even the grower can’t complain either. Just wish they had a fly, but might wait for a pair of Pinatubos to see if perfection can be improved with a fly.

    Very comfortable and flattering

    Love the stretchy material. Great for working out in since it lets your skin breath. Very durable, soft and looks great on. Highly recommend!

    Incredible underwear!

    I have been wearing Krakatoa briefs for several years now and won’t wear anything else. They hold up very well, they are very supportive of my manhood and feel fantastic! The fabric breaths well and is very soft. I weigh 165 lbs and stand 6’1”, I wear a small.

    Best underwear Ever!

    I have tried so many brands of underwear and these are by far the most comfortable. The fit is perfect, they don't ride up, the larger pouch provides just enough room without being outrageous. I wore these through one workout and immediately ordered 7 more pairs when I was finished. 10 out of 10!

    Best Fabrics To Touch My Skin

    I literally just got my package and the second I put them on I rushed over to my phone to write a review 😂, I don't think I've ever felt so "at home" in a pair of under garments until today. I'm a 32 in a half waist and I can faithfully say that you can just follow their size guide and it should fit PERFECT. These Haleakala's fit snug but not tight, have nice little anti roll-up bands at the bottom of the legs to keep everything in place, and a pouch with PLENTY of stretch that can accommodate almost anyone (as long as you're not weilding a battle axe between your legs). They are a bit on the "showy" side, as the pouch forms to your package, so it may not be the best thing to wear if you frequently change clothes in public spaces or around people, but aside from that they're the most COMFORTABLE things I've ever worn. Hats off to you Karkatoa, and you'll be seeing many more purchases from me. 👏🏾
