HEY ALEX, I HAVE QUESTIONS!
What's StratoPouch?
The Haleakala Brief is specially designed to have less materials between the legs, being 40% narrower, for an all day comfortable feel that won't bunch up.
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 Anti-Gravity Brief does not have an inseam and the fabric between the legs is 40% narrower for an all day comfortable feel that won't bunch up. The pouch is designed to be large enough to provide you room, while being double layered 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?
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?

The most comfortable underwear I own. I've been slowly replacing all my old underwear with Krakatoa as it goes on sale.

REVIEW
Some of the most comfortable briefs I have ever worn. The fabric is soft and comfortable, it’s very stretchy and conforms to all your bits well with the enhanced pouch keeping all your bits comfortable and in place. The strap seems to stay in place after a full day wearing them with jeans. I think these would be good to wear camping and when you’re hiking. The fabric does a great job keeping you feeling clean and dry.

The pouch is large enough so that it can fully contain my large balls and keep them apart from my thighs. The fabric is smooth and light, and seems to be durable.

I thought the Anti Gravity briefs were good. These are even better. More room, more comfort.
Was this helpful? - Gregory T.Verified BuyerReviewingHaleakala BriefsRated 5 out of 5 starsVery Comfortable!
These are the best underwear I have bought in a while! Soft, light, natural materials, plenty of room (I have bigger legs and butt which typically take room from the front). No discomfort with these when standing, sitting, working out etc… This is my third order as I replace my other underwear (Mack Weldon, Lulu, David Archy).
