HEY ALEX, I HAVE QUESTIONS!

What should I know about the fit?

The Anti-Gravity Boxer Brief is designed with a 7" inseam. The legs are designed to stay put, but be long enough to cover an increased amount of your legs to add a layer of protection from friction. 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.

    Love 'Em

    Took delivery of these and some others from a company with initials MW on same day. Loved these, didn't like the others. My Krakatoa Anti-Gravity Boxer Briefs are super comfortable, have a waistband that truly doesn't flip or roll, keeps the boys separated from my inner thighs, and material feels silky smooth. Almost like wearing nothing. And they allow your junk to be where it belongs rather than pressed tightly against your body. I'll be buying more. I also bought a pair of briefs and a pair of trunks, but like the Anti-Gravity (No Fly) Boxer Briefs with 7" inseam the best.

    Not normally a briefs of any kind guy...

    So like the title states, I'm not a boxer briefs guy or briefs of any kind but I've had these for several weeks now and I like them alot more than I anticipated. So I usually prefer boxer shorts for the freedom & so my member isn't crammed up against my family jewels causing sweating and sticking. Two of the worst feelings for me and why I don't use briefs. However I'm a scuba diver and when out leisurely diving at the lake on weekends or even at resorts for vacation with the wife she has pointed out, in a subtle but agitated way, that when I come out of the water my suit suctions to my body creating a noticeable outline down my inner thigh which apparently brought attention from some female divers and beach goers. So my response of "what am I supposed to do, I can't help it," wasn't satisfactory and so I was in the market for some boxer briefs as a solution. I've tried cotton cloth versions and they're far too sweaty. A buddy recommended Krakatoa and told me they're the best boxer briefs he's ever worn. I was initially concerned of their silly looking and feeling texture as silk type clothing ALWAYS make me sweat. But I have to agree with my buddy, these are very breathable and a very comfortable, soft feeling to them. I wish I bought more than two pairs now. Its like the ever popular women's leggings but for guys in boxer briefs form! I absolutely love the horizontal fly 1,000x better than the usual sideways fly. Now these are still boxer briefs so you still get the usual…
