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.

I love my Kraks!

Super comfy, very supportive, I don't have to "adjust the boys" 100 times a day like with most of the other supposedly supportive brands. I've tried several different brands one pair at a time. And Krakatoa are BY FAR the best ones I have tried! I'm expecting my third shipment shortly. My only complaint is that they don't have a fly. I asked, they answered! They're coming out with a crossfly version and I'll be all over them! Again, I love my Kraks!

I want to see brighter colors red, blue, corol or pink. I've purchased these in the past and would like to see them available again.

A Designer Who Finally Gets It

I’ve been wearing Krakatoa for a couple years now. Just ordered a new batch of trunks and as always, they’re perfect. I’ve recommended Krakatoa to several friends who at first thought I was strange for being so passionate about the subject. However, they’re the ones that won’t stop talking about it now. Alex at Krakatoa has finally cracked what appears to be a highly complex code and has produced underwear that is super lightweight, retains its shape all day, cradles balls like the hands of a loving someone who has nothing better to do than keep them from sticking to your legs, has a waistband that truly does not roll and is as smooth and soft as a cat. The rise is perfect; not too high or too low. They’re really flattering too. I feel like I could change my career the moment I slip them on. As always, well done!

Everything they said they'd be

Dayum. I've tried so many other high-end brands, but these are the first that work exactly as advertised. No rolling waistband, and it rides my hips without sneaking up my belly. No sticking balls. Hardly any adjustment needed through the day. Really, really comfortable. Really, really soft. And really, really worth the price. Now, how about adding a horizontal fly?

They rub you the RIGHT way!

Quality A+ Style A+ Fit A+ Comfort A+ Fabric A+ Affirmations A+ (you'll understand after you get your first pair!) As soon as I tried them on, there was something different... A material and fit, I have never felt before... I started feeling like a teen boy again, a certain strain on the fabric... "Damn, I love these!" I have damage to my low back, so often my P.T. is working below my waistline, even she commented on the underwear... And instantly, the "teen feeling" crept over me again... Did I mention, "I LOVE these underwear!" I've already ordered more!

Fit great - so comfy

Comfy underwear that are different than all the others out there. Great fit and design. Waistband design is just flat out fun - to boot it doesn’t cut in or get uncomfortable ever - it just does what it’s supposed to do, and it does it well.

Absolutely awesome! Even for short stocky guys.

These are the best. Incredibly comfortable. Typically trunks cut in to my legs as a short stocky guy. These actually stretch enough to fit comfortably.
