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.
A FABRIC TO OVERLOAD THE SENSES
Your skin never felt a fabric so soft and welcoming before. Three times softer than cotton, our high-grade, environmentally-conscious MicroModal fabric will make you rethink cotton and synthetics forever.
A POUCH FOR ALL OF US
Large, round, and deep support, without uncomfortable lift. Naturally odor resistant, it separates and cradles you, so you won't need to adjust anymore. Its double-panel construction keeps your privates more private.
A WAISTBAND THAT IS PURE LUXURY
Smooth and soft to the touch, the unflippable waistband won't mark your skin and keep you comfortable all day. To complement the art outside the waistband, its interior has positive affirmations to get you going at every break.
- Jacob C.Verified Buyer21 minutes agoReviewingAnti-Gravity TrunksRated 5 out of 5 starsSuper soft and comfortable!
Love how soft the material is, the length and fit around my thighs, I think it looks great from behind.
First time with underwear with a front pouch like this, I usually wear athletic style that is more tight around the front.
Feels super great, but definitely draws attention to your crotch, as very little is hidden there not sure if I would wear these to the gym, but they are super comfortable.

Very nice product. Well made. Especially like the waistband that doesn’t flip over. Already ordered more products.
- Jesse H.Verified BuyerYesterdayReviewingINTRO PAIR TRUNKRated 5 out of 5 starsIt’s not often I’m impressed!
I was a big fan immediately after putting them on. I’m usually a briefs guy but these trunks aren’t far off. The material is soft, there’s a nice pouch for the goods, and the horizontal opening is very convenient.

- Thomas R.Verified Buyer3 days agoReviewingINTRO PAIR TRUNKRated 5 out of 5 starsGreat fit and feel
First pair to try them out. Nice fit and feel. I tend to like a short inseam. These are nice and I’d like to see an even shorter inseam trunk available. Definitely recommend these trunks.

These are great… when I want just a little more coverage, but still need the guys to get a little lift, these were definitely the way to go. Great material, great fit… no complaints!
