About our trunks

Hey Alex, I Have Questions!

The Anti-Gravity Trunk is designed with a 2" inseam. The legs are designed to stay put, but can ride up a little depending on activities. 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 legs 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.

Best underwear I've tried

I bought one pair of Krakatoa trunks about a year ago, and they've been consistently the first pair that I wear after I do laundry. Super comfortable, amazing fit. Finally took the punch and bought a full week's worth of the Pinatubo, and I haven't worn them long but my initial impression is that I love them as much as the original and the fly is perfect.

True comfort

I have tried on so many different brands to find the perfect fit, and comfort. Krakatoa is by far the best brand out of the endless trial of underwear I have tried on in the past. I can honestly say it is worth every penny for the quality, comfort and everyday wear.

Best underwear I’ve ever worn

I absolutely LOVE these undies. They are all day comfortable, don’t need to be adjusted, and the waistband doesn’t roll. I will definitely be getting more.

Simply the Best

I’ve been on a mission to update my underwear drawer to something comfortable and stylish. I can across the Krakatoa on FB and decided to given them a try! Holy cow! They are without a doubt the most comfortable fabric I’ve ever had against my skin with plenty of room for my manhood and the boys. And a big plus for me … the waistband stays put! Bravo fellas! Just stocked my drawer with these fancy trunks! JB

I have been searching for underwear that is as comfortable and supportive as these for many years. I have bought 14 pairs in the last month and plan to buy more.

great draws

Very comfortable and the best I've ever worn. My only criticism is the lack of inventory of their stock.

OMG... love these things!

I threw out ALL my other underwear. I did. I was reluctant to buy these at first because I was not so sure. The price was good, they had the ***** pouch I wanted. And they hold my bits in the right place. It honestly does not feel like I am wearing underwear, they feel so natural. I want more... I am a real person in the world who is honestly loving these chonies!

My NEW favorite underwear!

Honestly, the softest and most comfortable underwear I have ever owned. They wash really well and don’t pill like so many of your competitors. I happily bought a second set of 7….I HIGHLY recommend them to anyone looking for a new brand.

Still the best underwear ever!

As before my new trunks did not dissapoint. They are so supportive with all the right room just where I need it. The material is the most comfortable thing that Ive ever felt on my skin. They keep everything right in place but at the same time if feels like you’re wearing nothing at all. The new horizontal fly is perfect! When its time go you just flip it right out and do your thing. Every man should try these underwear, you’ll never want to wear anything else

Don’t pass it up

Great choice. With so many choices, its hard to pick from dozens of FB ads and commercials. I ordered from FB and it did not get filled but the CEO himself answered my email and filled another order and gave a discount for the delay. That’s service. I don’t love the trunks as much as I like the boxer briefs but these (IMO) are better than Tommy John and David Archy and other competitors.

Best of the best!

Honestly, the most comfortable and best fitting underwear I have ever owned. Assuming the fabric holds up and doesn’t pill excessively, I’ll be back for more and you will have a lifetime client!
