COMPARE OUR BOXER BRIEFS
HEY ALEX, I HAVE QUESTIONS!
What should I know about the fit?
The Anti-Gravity Boxer Brief is designed with a 7" inseam. The legs are designed to stay put, but be long enough to cover an increased amount of your legs to add a layer of protection from friction. 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?
Our number one goal is that you're happy with your purchase.
If something doesn't fit right on your regular priced Krakatoa, let us know and we will make it right.
Try on a pair and make sure it's perfect in you. If it doesn't work for you, your first regular priced pair is covered.
After this first pair, all underwear must be unworn, unwashed, in the original condition and packaging that you received them for a refund.
If you bought multiple pairs, make sure you try ONLY ONE PAIR for fitting before you decide to use the rest.
INTRO PAIRS ARE FINAL SALE AND NOT RETURNABLE.
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've built a tough product with reinforced stitching that lays flat and the very best materials we could get our hands on.
That said, you should follow the care instructions.
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 before 52 washes or 12 months, we'll replace them for free.

- Daniel S.Verified Buyer43 minutes agoReviewingAnti-Gravity Boxer BriefsRated 5 out of 5 starsMy new go to underwear
These were my second purchase. Phasing out my TJ to krakatoa. These are so soft. Hold the boys in place gently during runs, lifts or everyday wear. No skin to skin contact with the boys softly cradled. The waistband is just snug enough and comfortable.

The boxer material is very soft. The waist band doesn't fold in half like boxer briefs from D. Trading Co. The boxers are true to size and are very durable. This is my second order, and this is all that I will wear for boxer briefs.

Terrific construction and super comfortable fabric. I’m 65 next month and have had lots of underwear in my time. These are by far the best I have ever worn. Comfort and build quality are off the charts.

The intro pair being just $10 is a great value. The material is very soft and the fit is good and doesn't require constant readjusting.
