With a front-forward 3" deep front pouch that connects to the back with a 40% narrower bridge than regular briefs, the Anti-Gravity Briefs breathe better and don't bunch up between your legs.

Our form-fitting ultra-premium MicroModal fabric holds you softly and leaves you feeling fresh all day.

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

40% less material between the legs.

HEY ALEX, I HAVE QUESTIONS!

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?

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.

The guarantee excludes damage caused by neglect or abuse, by intentional damage, accidental damage, color fade, pilling, stains of any kind, and deliberate attempts to damage the product.

Applies to any product purchased, does not apply to any product provided as a replacement.

WHICH BRIEF 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.

    Comfortable!

    I bought an original pair a couple years ago and loved the fabric. The fabric now is definitely more spandex feeling but still comfortable and looks great!

    "KRAKATOA" Best Underwear on Earth!

    I definitely had been missing out on the best underwaer until I tried Krakatoa Antigravity Briefs. The material is super soft and smooth. The pouch is very roomy and overall amazingly comfortable. Thank you Alex for creating the world's most comfortable underwear!

    Amazingly Comfortable and Sexy

    I’m a huge fan. They’ve now been through several washes, and I’ve worn them over really long, hot work days and have appreciated how comfortable they are. Then when the pants are off, I feel super sexy in these!

    Great Fit

    Purchased 4 pairs of Krakatoa underwear - 2 briefs, thong, and jock.

    The Anti-Gravity briefs have been a huge upgrade over some “traditional” pairs of underwear. The feel, the breath-ability, and support are top notch. My wife also has commented about how nice it makes my “bulge” look, so talk about a confidence booster!

    These are great - well constructed, plenty of support, semi-roomy, very soft. Perfect everyday wear.

    My boys love it.

    After buying my first pair of Krakatoa underwear, I was in love. This is my second order and I bought three. The thing that's great about these is the way they keep my BIG boys comfortably in place no matter if I'm sitting, standing, laying down, being active, or just chillin'. Previously I could never find underwear that would keep them both in place and out of danger (i.e. getting sat on or squeezed between my quads), making for some very uncomfortable moments. Nevermind being out in public and constantly making adjustments made me feel awkward. With my Krakatoa briefs, I experience none of that anymore AND they are super comfortable, like a thin second skin. I will buy only Krakatoa going forward and my boys appreciate it!
