About our Briefs

Hey Alex, I Have Questions!

The Anti-Gravity Brief does not have an inseam and the fabric between the legs is 40% narrower for an all day comfortable feel that won't bunch up. 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.

AWESOME Customer Service

After a "trial" order of one pair of trunks, I placed two more orders for additional trunks and briefs. First off: the products are AWESOME! I ordered a pair of trunks for a friend for his birthday and by mistake I ordered small instead of medium. I didn't notice the size mistake (totally MY fault) until I gave the gift to my friend which was a whole month after purchase. I contacted Customer Service and quickly received a response from Arthur. He is sending out the correct size for my friend at no charge and is MAKING IT RIGHT despite my error. This is AWESOME Customer Service. I will continue to purchase this brand of underwear. These offer a great fit...make you feel sexy...and keep "the boyz" in place. BTW: I'm 66 years old and refuse to dress/look like an old fuddy-duddy.

Softest briefs EVER

Anti-gravity is right! Let ‘em hang, but with support still. Feels like I’m wearing nothing. Super soft, stretchy and perfect fit. Look is fantastic. I will say you may want to upgrade a size if you need extra room in the front pouch (if you know what I mean). Customer service is amazing as well. Alex personally messaged me to solve an issue and couldn’t have been more kind and professional…..and prompt! Definitely a big fan of these briefs and brand

Outstanding briefs.

These are truly the best briefs I've worn. The fit is great and the fabric is so soft. I love the pouch because it doesn't have the awkward hammocks, slings and whatever else other brands try to get you to buy. My only wish is that the pouch was a just a little bit bigger, it's always been a challenge getting room in the front to begin with, however these definitely help. I will be purchasing more.

Quality Product

After a couple of washes, the quality is excellent. Happy with the fit — the pouch has sufficient room and keeps everything in place as it should. Also, nice fabric — just an all-around quality comfortable brief.

Briefs are the real deal

I love the briefs! I recently traveled to Ireland and these went along. So comfortable and soft. Also, they pack well. They only take up a small space in my luggage. I wanted to be comfortable and cool in Ireland. These did the trick! I highly recommend these for home or travel

Might start wearing briefs again!

I ordered medium sizes of all three underwear varieties but should've gone with large especially for the briefs as they're a bit too snug. I'm 6'3" 200lbs and based on the size chart, I thought I could manage Medium but should've known better. That's no fault of Krakatoa! Their products are up there with the most comfortable I've ever hiked up, and I'll absolutely get more when it's time to retire pairs from other brands. I'm a boxer brief guy, but went with briefs for the first time in 25 years to mix up my bag... they're very high quality and my wife enjoys the view! I'll just go with my gut and order large next time. I can't recommend Krakatoa enough!

Briefs vs. Boxer Briefs

they look and feel fantastic, both have VERY good support for the boys, I love both styles as well and always have. However, I think they should use the same leg elastic for the Briefs as the Boxer Briefs have and then they would be perfect. Overall I am very satisfied with the product and will continue to purchase more in the future. There is also a little overkill in the packaging too, eliminate that and cut the price and this will be 100% awesome. My opinion only, hope it helps everyone, thanks

Thnking about a pair? Just do it!!

The fit is perfect! In other brands, I buy size Large 36-38, but this Large 38-40 is the same fit. I'm so tired of having my stuff squished between my legs, especially when I wear jeans. The fabric between the legs in these briefs is narrower than others making them NOTICEABLY more comfortable to wear. And the bigger pouch supports it all, keeping everything up and away from between my legs. Because of that, I get why they call them anti-gravity briefs! They have really perfected a supportive fit without being tight and binding. Fabric is very light and stretchy. Really, the most comfortable briefs I've ever worn.
