About our Briefs

Hey Alex, I Have Questions!

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.

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.

We try our best to ship items the same day we receive your order. Shipping times can vary depending on your location. Inside the US you can expect to see your package between 3-5 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.

Briefs are finally an option!

I have not tried briefs in years because they are always too tight and restrictive. These have a man sized pouch that allows sufficient room to make them very comfortable. Also, the fabric and waistband are amazing. If you’re on the fence about trying briefs again, these will make you a brief wearer again!

I thought briefs were just off the table...

Finally a Uber soft, no bunching, no leg brief for people who need a pouch! I've tried so many briefs over the years and Krakatoa finally delivers, letting you rest comfortably in a Natural position! Appropriately covering the butt, and high cut legs and a moderate rise for a modern yet still conservative look. I'm a medium, but prefer a size large which is more casual and relaxed but still supportive and looks good.

I love the briefs

I really like these briefs! The fabric is great and clings to your body nicely, and yet allows room with no problem. I really appreciate the narrower fabric in the crotch. it enables the pouch to caress your goods very well. The fabric in the pouch is flexible enough when my room is required. I love them, and will definitely be buying more!

AWESOME Customer Service

After a "trial" order of one pair of trunks, I placed two more orders for additional trunks and briefs. First off: the products are AWESOME! I ordered a pair of trunks for a friend for his birthday and by mistake I ordered small instead of medium. I didn't notice the size mistake (totally MY fault) until I gave the gift to my friend which was a whole month after purchase. I contacted Customer Service and quickly received a response from Arthur. He is sending out the correct size for my friend at no charge and is MAKING IT RIGHT despite my error. This is AWESOME Customer Service. I will continue to purchase this brand of underwear. These offer a great fit...make you feel sexy...and keep "the boyz" in place. BTW: I'm 66 years old and refuse to dress/look like an old fuddy-duddy.

Softest briefs EVER

Anti-gravity is right! Let ‘em hang, but with support still. Feels like I’m wearing nothing. Super soft, stretchy and perfect fit. Look is fantastic. I will say you may want to upgrade a size if you need extra room in the front pouch (if you know what I mean). Customer service is amazing as well. Alex personally messaged me to solve an issue and couldn’t have been more kind and professional…..and prompt! Definitely a big fan of these briefs and brand

Keeping it all together

These underwear are so comfortable. Finally, underwear that fit well and keep everything together. I purchased the medium size at first. Then thought I'd try a small to see if they fit any better, since my waist is right between small and medium. I like the fit of the small ones much better. I will be ordering more of them.........Thank you!

Great Briefs!

I love the fabric and the feel. Customer service was phenomenal! The only issue I had was the sizing. I like my underwear a little looser than normal. I’m usually a large but the way the sizing is I went with a medium and they were a little snug. But other than that probably my favorite underwear as far as comfort goes.

AMAZING

The anti-gravity briefs feel as if you are wearing nothing but still offer the support the boys need throughout the day. There is also the added benefit that they make my butt look good �

Premium Comfort and Quality

Bought the briefs and the quality is great. Super comfortable with an sizable pouch that allows for a "natural hang" with gentle support without smashing the goods. I have tried a lot of different brands that claim it feels like your not wearing any underwear at all which wasn't entirely true. Wearing the Krakatoa's truly feels like you aren't wearing anything. The fabric is the perfect weight, not too thin. The fabric seems to breathe well and keeps things cool. The waist band is so comfortable you can't feel it, either. I bought a few pairs to try them out for awhile and I'm definitly sold on them. They may seem pricey, but in my opinion you can't put a price on comfort and quality. Ordering six more pair as soon as I finish this review!
