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.

Comfortable and breathable. Shorter than I usually wear but bought for wearing under shorts. I don’t like when my boxer briefs peek out of my shorts.

The right fit - with a fly. The pouch is where it's at, the waistband won't fold on you and the material is barely there. It's like going commando but with full support. What more could you want?!

I've been looking for the perfect underwear for decades, and that is literally no exaggeration. For years, I was a sad, saggy boxer person, and then finally graduated to boxer briefs. But, I was never quite happy with the way they fit. Over the years I've tried briefs, boxers, trunks, and more, and nothing really satisfied me. Either the pouch would be great, but the waistband would fold over and wrinkle badly, or the waistband would be okay, but the pouch would be horrific. I must have tried over 30 different brands and types over the years, and was ready to just call it quits and settle for less. But THEN, I discovered KRAKATOA! These are the best trunks I have ever owned by far, seriously. I absolutely love them, and my only complaint (if there can be one?) is that I want them in more colors. Come on dark red! Right now I have some Anti-Gravity, Vesuvius, and Pinatubo trunks, and I mean it when I say these are completely perfect. I'm not a "slim" guy, and these are exactly what I've been looking for all of these years. THANK YOU!
