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.

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.

Krakatoa Underwear 3 Pack Vesuvius Trunks - Black Rock Review

Love my Kraks, always there to “support” me in my everyday activities, no more adjusting the boys! Can’t wait for the “fly addition”!

Stand out in a crowded field

There is a LOT of men’s underwear out there in the high end category. I’ve tried a lot of the brands. What it comes down to for me in a boxer brief/trunk is how the design deals with keeping the boys isolated from the thighs. And, in doing that, how much room is left so that they don’t act as compression shorts. Krakatoa has landed in a very good place for me on the isolation front as well as the roominess front. The fit is outstanding. I have tried all three cuts and prefer the trunk to the boxer brief. I’m not a fan of the brief - I just dont like the fit, but no matter. It is surprising how the difference in length has significant differences in how they fit. The final issue that is critical is the fabric. I have found brands that fit great, but make me sweat and don't breath. Other brands breath well, but are too light and flimsy. Krakatoa uses fabric of a good weight with a double fabric front panel, but that breathes exceptionally well. Getting all of the requirements for a well performing trunk/boxer brief is really hard. In this very crowded field, Krakatoa is a stand out and well worth the investment. I recommend trying all three styles to find the right fit for you.

Good Stuff

I recently ordered underwear from several companies, searching for the perfect pair. Krakatoa has a great fit and feel. I love that the back is higher than the front (can't say that about all the other ones. Mine were the boxer brief trunks. My only complaint is there is no fly. That would've made them perfect.

Fantastic fit and support

I purchased a pack of trunks. The fabric is extremely soft and lightweight. I’m very active and usually wear compression shorts or a jock, so I was skeptical they wouldn’t have adequate support for my sizable **** & balls. I was pleasantly surprised. They kept everything in place without any inappropriate floppage, which is very embarrassing in social and family situations. Thank you!!

A model for customer care

The underwear is fantastic. The material. The waistband. The fit. What sold me was the lengths Alex will go to in helping find the right fit and making his customers happy. If a company deserves your business, this is the one. And you will be oh so happy with your purchase.

I prefer the boxer brief. This material is the most comfortable, most supportive, cooling and comfortable. I highly recommend them for anyone. The customer service is off the charts too.

Fabulous product and company.

I had a problem with the USPS losing my order and Alex was very helpful and sent a replacement order right away. When I finally received the original order he told me to keep it when I asked to return it. Fabulous company and I totally love the trunks. Customer for life.

Gave them a try, bought more. The waistband doesn't roll!

I've been buying new brands of underwear off and on for 2 years, these are the best with one drawback. The legs of the boxer briefs do stretch throughout the day and ride a up a bit. I'm 5'10" 225 with big thighs, so it could just be me. I would go for the briefs but not until my weight drops more. I've tried other brands with a pouch and they are uncomfortable after some time and the waistbands always roll down, these do not! Just ordered my second set of 3 yesterday.

Comfy and Sleek

I wanted to try these out after I picked up some other trunks and briefs from Krakatoa. I wasn't sure how the band design would look in person, but I really enjoy it, and they are very comfortable (as expected). I'd definitely recommend picking up a 3-pack.

Excellent Fit!

After initially purchasing the brief version, and not being completely satisfied with the pouch coverage, discussed my situation with Alex, and the trunk style was recommended for more coverage - and he was absolutely right! The fit is great, the fabric is so smooth you forget you’re wearing underwear! Highly recommend. My pants waist size is 40, I bought the Large, and they fit just right. And the customer service is the best!

I like them. I don't see a huge difference in how my boys feel,but maybe they aren't big underwear no matter what

Best Underwear Ever!

The fit, the material and the comfort are all the best I have ever had and I have tried more brands of underwear than most people so I know what I am talking about. This is my new brand.

The Boys like the roominess

Besides the BEST Anti-Roll waistband, this Pouch is the roomiest of any I’ve tried. Great breathability too so no SwAss…..How do I get my wife to to suggest replacing all my other Briefs?
