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.

    Best pair I have

    Comfortable, thin, cool, and the boys are where they need to be. Not much more to say, other than that I’ll be loading up my drawer with more Krakatoa here soon.

    Seriously I want to replace all my boxer briefs now

    I didn’t believe it when other reviews said the same thing. I can vouch for the validity. I had one pair, then four and will order more. Most comfortable and supportive pouch of any boxer briefs I’ve tried and I’ve tried them all. This is the best.

    Comfortable and functional

    These are very comfortable and keep everything where it needs to be. There’s no chafing and the horizontal orientation of the hole in front is more convenient than the typical vertical orientation.

    I highly recommend!

    Best yet

    I have many types of pouch underwear and these are simple in design yet effective in form. Will return to purchase more.

    Very Nice!

    I absolutely love these! They are very comfortable and very soft. So far they refuse to get clammy even while sweating. The waistband doesn't roll over like every other pair on the market. Barely notice them at all.

    Quality control so far is excellent. I have a pair that is about a year old from an earlier purchase and the stitching, waistband and fabric are still rip free and the stitching has not unraveled at all.

    I was skeptical of the horizontal fly but now I am a huge fan! I am planning on purchasing several more pair in the future.

    My New Favorites

    I grew dissatisfied with my old brand and have purchased multiple new boxer briefs lately looking for "the one." These are, hands down, the best I've tried. Great fabric, no rough seems, really comfortable front pouch, and a "no roll" waistband that actually doesn't roll, even on guys without a flat stomach. They're not cheap, but they're definitely worth it, in my opinion. I've bought four pairs so far and will be buying even more in the future as I swap out my entire boxer brief wardrobe.

    Also just gotta say that Alex seems like an awesome guy. I'm glad to support his small business.
