About our boxer briefs

Hey Alex, I Have Questions!

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.

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 leg 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’m wearing underwear?

I love these so much, ever since I first tried the trial pack a couple months ago I fell in love with the material I sometimes forget I have anything on it’s so soft and flexible and has plenty of room for the bits not mention helps visually never felt like I had Bulge like some guys but I definitely can see it now. I have purchased Underwear here twice Now and I’m excited to see new colors and hues. If you do anything do yourself a favor and at least try the trial pack or the basics 1 of everything pack.

Super Comfy

Most definitely one of thee best and most comfortable briefs I have put on. I'm mostly in dress pants and I gotta say they stay put don't ride up and the elastic band does not fold over like most underwear do. I highly recommend Krakatoa and will be purchasing again.

Anti-Gravity Boxer Briefs - Vesuvius Collection

Very comfortable, almost like wearing nothing. I would maybe try ordering a size smaller next time to get a slight snugger fit.

Mobile, comfy, supportive

The material is the best out there in terms of comfort! Being a strength athlete, finding proper underwear can be challenging but these have proper support (especially if you have a little extra heat to carry) Breathable, soft as heck, yet properly supportive… replacing my entire underwear drawer with these

I'm now a believer!

I have tried several different brands of underwear and have had trouble finding any that are comfortable AND give me support I need! It is one of the only brands I've ever put on that has enough room in the pouch to remain comfortable all day without any adjustments. I will be buying more soon.

My new go-to for daily comfort

When I ordered these, I thought they’d be like some of the standard modal boxers out there but after a few hours of wearing, I became a convert. They’re comfortable and supportive. The boys are front and center and the leg openings don’t ride or chafe. It doesn’t have the biggest pouch on the market but it’s larger than most and feels great for daily wear. Liked ‘em so much I immediately purchased another 3.

The Real Deal

I've tried a TON of different underwear brands, searching for a boxer brief that is meets my big 3: comfortable, supportive, looks great. Surprisingly, this is the first I have found that fulfills everything I have been looking for. Unlike many others, the material is perfectly soft and smooth without clinging uncomfortably to the boys. Everything feels held in place without feeling too tight and restrictive–they breathe so well, it almost feels like wearing nothing. If that wasn't enough, they look great both front and back! Major kudos to the front pouch design in particular. Feeling cozy and confident throughout the day wearing these, I'll be buying more for sure. Thanks Krakatoa!

Best pocket pouch out there.

Hey Alex, Thanks for pursuing your small business against so many underwear companies out there. I buy a lot of underwear trying to find the best and most comfortable out there. Alex your holds second place out of 15 different brands I even consider. The size of your pouch and it's geometric design keeping my male hardware I place no matter any body motion or excerise. Most underwear balls work themselves out of the pouch of other underwear and then the seam presses on then making them very uncomfortable and a need to go to a restroom to reposition getting all hardware back into a comfortable place against. That underwear usually goes to the back of the drawer. This just doesn't happen with your underwear. Love them plus they make those Important parts of the male anatomy look anazing!!! Congratulations Alex. You won me over, Jacob

Excellent Fit

I liked the ad when Alex asked, “What am I? A Ken Doll?” That got me to click the purchase button. I bought three and can’t wait to buy four more - a pair for every day of the week. I’m 65 and have tried all kinds of underwear, as you can imagine. These are the best fit I’ve ever experienced.

Like a second skin, only cooler!

My GF bought these for me. I admit I was skeptical at first but these are so great! I can’t even tell I have them on and they keep me very cool! Absolutely love these!

Same as the other set I got here

I tried this out because they looked interesting and I'm always looking for that sweet spot in boxer briefs: something that fits comfortably and yet also supports me during athletics (cycling, weights, cardio) and doesn't leave me swinging in the breeze. I may have found my forever undies... these do all and more. Super comfortable. Great support. And separates the pieces so that they're not in the way. Bravo.

Almost perfect. But not quite

Almost perfect but not quite. I was excited to try these out. I love the super soft and stretchy fabric and the roomy pouch that is very flattering. How ever I absolutely hate the way the pouch is cut at the back it tends to push your balls forward especially when I walk upstairs the stitching on the back will catch one of my balls and push it farther forward then the other witch is uncomfortable. If they made the stitching for the punch towards the back go all the back instead of a “U” shape then I would love it. Lastly I didn’t love the silk screened tag, maybe it will ware in but when I first tried them on the tag was very noticeable and annoying

Comfy, soft, and room to breathe

The material is soft with no raised seams or itchy tags. The legs are snug enough to stay put and not bunch up but not so tight as to cut off circulation. My guy parts are happy with the extra space and it makes everything from sitting to standing to cycling easier. Well done, Krakatoa—I was never a boxer or boxer-brief guy before, but your design made me a convert.

Better than advertised.

These are almost like wearing nothing, but with the perfect amount of support. Soft, the legs don't roll up, the waistband doesn't flip.

Simply the best

Alex has made the best men’s underwear. I love how they feel and support. It’s like they were molded to fit your body perfectly. All you do is step in and pull up and everything is in the right place and stays there all day. No adjusting, no rearranging, no embarrassing pull or tug when you stand up. PS I love the designs on the waist bands and the positive affirmations on the inside are over (or under ) the top.
