THE FEATURES YOU REQUESTED
Every little detail was obsessively fine-tuned, to deliver you an underwear experience like no other:
PERFECT SUPPORT
All the Room, None of the Slack.
Less material, more support.
It's like magic the way that we've fit a nice large pouch along with a narrower connection between the legs, while providing full support for your activities.
Besides looking great, the Anti-Gravity Briefs are your go-to Briefs for daily wear.
SMALL DETAILS, BIG RESULTS
We Obsess With Your Comfort
The narrower bridge connection between the pouch and the back allows you to breathe much more effectively, and reduces bunch-ups between your legs.
THE FINEST MICROMODAL FABRIC
Exceptional Softness and Breathability.
No synthetics here -and no PFAS.
Feel softness like never before with an ultra-premium, hand selected 95% MicroModal fabric. We source only the best MicroModal because comfort is our #1 goal. (Learn about MicroModal). We just add 5% of Spandex to allow for it to move with you.
We never skimp on the quality of our fabrics and materials, neither on the craftsmanship. These products go on your softest, most sensitive parts. We won't settle for anything less than the very best.
UNFLIPPABLE WAISTBAND
Art On Your Body.
Our waistbands are wide, smooth, don't leave marks, and are truly unflippable, offering a secure fit that prioritizes style and your comfort over branding. We focus on modern designs rather than flashy logos, framing your body beautifully.
Inside, you’ll find positive, self-affirming words designed to motivate you daily, inspiring you to be a better person to yourself, and to those around you.
Experience the perfect blend of style and substance with a waistband that uplifts and empowers you.
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.

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.

Was this helpful? - PETER S.Verified BuyerReviewingAnti-Gravity BriefsRated 5 out of 5 starsGreat briefs
I have different versions of Krakatoa's underwear depending on what I wear. I bought these as an alternate to the Pinatubo jock and thong for times when I wear tighter and or thin clothing and I want to maintain a look of "modesty". As the description says, these are roomy and front forward, meaning they still show the package well while maintaining a nice lift. It won't look like your junk is going down one leg in tight clothes. While I love the Pinatubo's, they have a little more drop in the pouch than these and the Vesuvius forget it, your freeballing at that point, they are awesome! Same great fabric and waistband and a nice cut.
