About our boxer briefs

Hey Alex, I Have Questions!

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.

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.

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.

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 accomodate 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 leg is a thing of the past.

Please allow 2-4 days for processing, and the usual shipping times from the USPS: 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.

Our number one goal is that you're happy with your purchase.

If something doesn't fit right, 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 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 a pack with multiple pairs, make sure you try ONLY one pair before you decide to use the rest.

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'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.

Better then the rest

I switched to Krakatoa from ex officio about 8 years ago on the recommendation of a friend that was a through hiker who had just completed the PCT. He swore by them and I had been pretty disappointed in the diminished quality of my recent purchases of the other brand. I bought 3 to start and loved them because they were comfortable and supportive and eventually switched over to just Krakatoa. My first pair wore out in January lol. So 8 years of hard service - hiking - biking - skiing - being worn in the ocean and pool during travel and they lasted 8 years without the waist band failing or stretching etc.

Once you go Krakatoa you'll never go back

These are my new favorite underwear! Super soft, luxurious and smooth fabric that feels great to wear. Dumping all of my other boxers and filling the drawer with these. Also the fly is in a great location and provides much easier access for you or your loved ones. These deserve better than a 5 star rating.

Best ever!

I couldn't love these boxer briefs more. They are super comfy and supportive and are my go-to underwear, especially when I exercise. I've definitely paid the price on those rare occasions I didn't have my Krakatoa on! I've purchased several pairs and each time I've noticed a small improvement - when I didn't think any were needed! Thank you!
