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.

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.

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. If your item has any structural damage resulting from a manufacturer's defect before 52 washes or 12 months, we'll replace them for just the cost of shipping.

Each Krakatoa Collection comes with a specific pouch and hem.
