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.

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.

The Fly!

I’ve been wearing all versions of Krakatoa for some time now. Actually, I live in them because they are so damn comfortable. I was a little suspect of this new fly having experienced gaps, flop outs and so on in the past. Bought a 7 pack last week and gotta say Alex’s design is awesome! The boss is easily and comfortable freed when I want and otherwise the experience is just like the Krakatoa I’ve come to love!

Woody and the Twins R So Happy

I took advantage of the “Try A Pair” $10 Pinatubo briefs from Krakatoa. I found the briefs secured my package without smooshing. The material is soft and breathable. I was impressed and ordered a 7 day pack. Thank you

Best underwear ever!

This product has a quality level well beyond any of the same category I’ve ever tried. It is no surprise as Alex always makes sure to make everything he is involved with the absolute best! Each feature has been carefully designed for specific reasons and together result in a product that is miles better than any other choice. I won’t be going back to the inferior brands, I made sure my son and I have enough Krakatoa for every day so we don’t have to settle for what we wore before. If you haven’t tried Krakatoa yet, then you are definitely missing out!

Great feel

After always buying by price, and not comfort, never in a thousand years, did I ever think I would spend this kind of $$s on underwear? I was always that guy buying the Hanes bulk pack for maybe $20+/-. I saw the offer on FB to try a pair of boxer briefs and said "oh **** why not." At the same time, I bought into another brand with a "money-back guarantee". Everything literally arrive on the same day, so the comparison started right away. Long story short, after comparing, washing, and wearing, I returned the other pairs and bought the Pinatubo 7-day week pack. The Pinatubos are by far the most comfortable briefs I have ever worn. The comfort, feel, fly location, colors and most importantly, the waistband does not roll down on this Dad's body, making these a Five Start purchase ⭐⭐⭐⭐⭐

Have tried too many brands to recount. Enough for the wife to notice and bring it up! Like the waistband, length and fly on these. Love the fabric. Cant wait to try the Haleakala that I told was coming out. Might have just found my final underwear company! Don’t change anything!!

Second 7 pack purchase.

I was so impressed with these underwear I took advantage of the holiday discount and bought a second seven pack. Best underwear I have ever purchased. Love the color options in the seven pack.

Best there is!

I found Krakatoa a couple years ago and couldn’t believe how comfortable they were. All of the issues that I’d had with men’s underwear from bunching fabric and excess heat to lack of support were finally fixed, and I’ve been a satisfied customer ever since. With the addition of the Pinatubo line, and the horizontal fly I think they’ve improved an already perfect product! Rarely is it convenient to use the fly on your average boxer brief because you have to fish around to get out of it, and it’s often pretty constrictive once you do, but not with these. It’s very natural to use without compromising any of the support that Krakatoa is known for. If you haven’t tried these yet, do yourself a favor and order a pair (or 3)! You don’t know what you’ve been missing! Thank you for making the Best underwear a guy could ever ask for :)

Best Underwear Ever!

I can’t say enough great things about Krakatoa. I have considered myself as somewhat of an underwear connoisseur, having tried many many brands before and these are definitely the most comfortable underwear that I own! I never have to readjust or shake a thigh to release my package from sticking to it. And now, with the new horizontal fly, access is easier than ever. As if that weren’t enough, I love the way I feel and look while wearing them! I am a fan for life, thank you Krakatoa :-)

nice fit

I bought these becasue the anti gravity boxer briefs have been out of stock for a long time. I was skeptical about the pouch size because it was a different design but to my surprise they are the same.

I've tried it all and the search is finally over.

I got on the SAXX train from the start. Loved the concept and feel as i spend time in the mountains often. Found that the got loose and didn't contain my rhino thighs or huge butt. Tried a few others and ended up moving to the Stance. Started off great, loved that I didn't have to hike up my drawers every time I bent over. But alas, they deteriorated quickly which is frustrating for the price. Finally stumbled on Krakatoa. Really appreciated the low cost sample pack, great business move. Better price for a better material. Guaranteed 52 washes, even better. Found that the 3d pouch does the job perfectly all day. Once the Pinatuba collection came out I was all in.

End of the underwear search

The absolute perfect pair of drawers. It’s that simple. Soft, supportive, secure, separation, sensational…I'm out of S words but you get the point. Buy these.

Fantastic comfort and fit

Was really excited to try the new Pinatubo as I loved the Krakatoa but really missed not having a fly front. Been wearing the Pinatubo for a few weeks and they hold up every bit as good as the original. I never write reviews, and certainly did not think I would write a review on underwear, lol. Trust me these are the best! Best comfort, Best fit, Best support ( even if you are carrying coconuts instead of grape nuts ), and they are durable. Can’t emphasize it enough, throw out your tighty whiteys and invest in real comfort.
