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.

These feel so smooth and sweet!

These underwear are my new favorites! They’re so silky soft that you barely feel them but you’re totally supported. Nothing heavy is banging around and yet there’s absolutely no pinching or constricted feeling anywhere down there. Held and supported like just like you want to be - free but so easy. Holds everything a little forward for a nice, discreet show of what you have to offer. And definitely hugs your butt without stretching out while you’re wearing them. Just the best!

My search is over

I have invested hundreds into different brands of underwear to find the right material, cost, and fit for me. I am a stocky 5'6 man with a 34'' waist. And I must say that this companies underwear is by far the best in the market right now. My past underwear would ride up, tear between my legs, and just down right make me sweat, Krakatoa doesn't do any of that even with regular washes and usage. I have bought one trunk pack so far and I intend on making another pack purchase today.

These underwear are amazing. From the minute you step into them, everything falls into place. And everything stays in place. All day. No adjustments necessary. No pinching. No creeping. No smushing. Just comfortable, happy, well supported goods all freakin day.

Great underwear at a fair price.

Excellent products. Both the briefs and the boxer briefs offer excellent support and are quick drying. The stay cool even in hot and humid Miami weather. Will be purchasing some more in the near future.

Now I understand

Nnow I understand when women feel sexy with their under garments. Krakatoa is soft to the skin, and give the proper support while giving room where it’s needed. Will buy more!

First Timer

Love the fit and length...exactly what I was looking for. The material is better than expected. Only small thing I noticed is a small oddly shaped bump out in the crotch seam...not sure if it will eork out over time.

Best Ever

Very comfortable, amazing fit, and the extra room in the front is SO wonderful that no other underwear comes even close. Thank you for creating such an amazing fitting underwear for us men. Again, the best thing I've ever bought.

Nice trunks, but I prefer briefs

I prefer briefs for one reason, when my equipment is soft, it is still pretty big, so I prefer to wear it to the right side. With briefs, it tends to stay put through the day. With the trunks, I have to occasionaly move it around when it falls down. I must say, these trunks stay put and are very light and not hot at all. I wish the pouch was a little wider at the sides to more easily accomodate my equipment, but again, I prefer the briefs more.

Best ‘Fancy’ Undies I’ve Owned

I always feel slightly indulgent buying “fancy” underwear because I feel like standard briefs and boxers have kept gents clothed just fine for an awfully long time, but “good enough” is uncomfortable and unnecessary with these excellent trunks. They’re, hands down, the best I’ve tried, and I’ve been searching for the perfect pair for 20 years. The lift-and-support system is elegantly simple. The fabric and construction are the best I’ve found, and, so far, they’ve performed well wash after wash. I’m extremely pleased with these new favorite underwear, and their price is accessible enough for me to purchase more along the way.

Damn Excellent Underwear

Hands down best trunks I’ve ever had. You don’t notice them. This means you aren’t adjusting cuz everything stays in place, the waistband is perfect as well.

Favorite undies so far

These things feel amazing, well what you do feel anyway. It’s like going commando, while still being supported. I’ve tried lots of different underwear and these are by far my favorites.
