COMPARE OUR TRUNKS
HEY ALEX, I HAVE QUESTIONS!
What should I know about the fit?
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.
What if I'm in between sizes?
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.
What's MicroModal fabric?
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.
Why such a big pouch?
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 accommodate 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.
When will my item ship? How long will it take to arrive?
Please allow 2-4 days for processing, and the usual shipping times from the USPS or UPS: 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.
What is your returns and refunds policy?
Our number one goal is that you're happy with your purchase.
If something doesn't fit right on your regular priced Krakatoa, 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 regular priced 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 multiple pairs, make sure you try ONLY ONE PAIR for fitting before you decide to use the rest.
INTRO PAIRS ARE FINAL SALE AND NOT RETURNABLE.
How do I wash my Krakatoa?
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.
What's your 52 Wash Guarantee?
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 are one of my best pair. I had some concerns being a bigger guy and the 2" but I worked all day in them and they never rode up.

I got a ton of ads for this and usually I ignore products that I get a bunch of ads for but I caved and tried them. As a thick thighed guy, these are hands down the best underwear I’ve had in a long time. Wore them recently on a day of walking and exploring and had no chaffing. I was really surprised, and honestly can’t wait to order more!

I figured any boxers named after a volcano deserved my attention, so here I am with the best fitting trunks I've tried. The pouch is obviously designed by someone here that understands the physiology and shape of the branch and berries and what it takes to hold it all comfortably. I've ordered some more. Try the intro trunk. They really are that comfortable.

I am very happy with my new Krakatoa Trunks. The fabric is soft and supportive. The shorter trunk style is more comfortable and supportive without feeling like I am wearing a diaper. I'm not a fan of the separate pouches that are popular now or wearing my penis down over my balls, I can still wear mine to the side with this pouch style.
My only dislike is the patterned waistband, just my preference.
Well Worth it

Thanks to Krakatoa for their introductory pair of underwear. They are incredibly soft and have the right amount of pouch for my package. These are now my "go to" underwear for massages, hookups, anywhere I might be seen in my skivvies.

These were the best feeling and lightest men's boxers I have ever worn. Great looks, light feel, like you're wearing nothing. Will be adding more of these to my wish list.
