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.

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

Really comfortable underwear

These are extremely comfortable - love the pouch as there's no squashing nor any need for the usual regular adjustments throughout the day. I'll be getting more of these.

Feeling good

Great quality materials and stitching. Feels like you've got nothing on. I need to size up from expected and Alex sent me a new pair for free without having to exchange. A+ customer service and responses.

Great new underwear

Great product so far. Fabric is great, very comfortable. They arrived pretty quickly from ordering online. Price is a bit high with so many underwear brands out there on the market, but if these hold up well, will be 100% worth it!

Love the fit and sophistication of these briefs!!!!

Good briefs. Suggested improvement.

Great material. The waistband is comfortable. My only suggestion is for the elastic in the legs to be just a bit stronger. It stretches out a bit too much after a few hours of wear. Not bad but loose enough that it feels less snug on the rear.

Awesome fabric

These are great briefs, love the fabric and the cut. The one thing that could use a little more fabric is the pouch. I had to stretch it out to be more comfy. It’s a bit snug, no hanging going on here. But, overall a fantastic pair of underwear!

SOFT & Comfortable

I was skeptical at first because I like wearing underwear that has the dividers in them, like Saxx, 2undr, etc... I dont like the boys touching my legs. I thought I would try them out anyway. I am glad I did. They are super soft and keep the package nice and tucked away from my legs. I will be getting more!

So soft and smooth, the most comfortable underwear I have ever owned. I use to wear Tommy John’s but these are more comfortable and more affordable

Two pairs have arrived. Amazing fit and feel. Love the waistband. No roll over. Feels like commando but my balls are separated and supported and contained. I am an old guy and have issues of sweat, drooping, escape. Your straightforward approach attracted me. I am not disappointed. Thank you Bill Bowden Sent from my iPad

Best underwear I’ve ever worn

I effing love these undees - super comfy and they feel great when I have them on. I bought briefs and boxer briefs initially to try them out. Just decided to buy a pack of trunks cause I think I’ll like them the most since they kinda give you the best of both Thanks for creating an excellent product!

Best undies EVER

I love the way they support what's up front. Cradle but do not bunch or bind. The fabric is so soft and the elastic does to have a tag that scratches. Buy these. You can't go wrong!

BEST undies EVER!

KRAKATOA brand undies are the most comfortable underwear I’ve EVER worn. I love the decorative no-rollover waistband and the light/silky fabric that’s cool and comfortable but sill supportive where you want it. KRAKATOA underwear will definitely be the only brand I purchased in the future! Thanks Alex — great product!
