About our trunks

About our Boxer Briefs

Hey Alex, I Have Questions!

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.

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 legs 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.

Silky soft

I have tried a lot of underwear. These are some of my favorites. They are silky smooth and the pouch provides good space.

Very comfortable underwear, I ordered the intro pack. Nice wide waistband that doesn't roll or fold over and the pouch for your "boys" is really nice as well.

Great underwear

Love the fit of both but ended up liking the trunk style the best. Provide great support and room.

Perfect Balance

Both the trunks and boxer briefs make you feel supported where you need it without constriction while also allowing movement and flex for full range of motion throughout the hips and thighs. The ergonomic pouch cradles and separates but does not necessarily draw attention that would make you stand out at the gym or shout "look at me" as an evening progresses. These have definitely become a top-tier choice in the drawer, and I will be adding to them moving forward for sure.

Super comfy

Are you a victim of online ads? Girl same. The algorithms are getting better. These are super comfortable. I ordered the intro pack of trunk and boxer brief. Will likely order a three pack of the boxer brief in the near future. I like the trunks as well, but need a little more coverage so my thighs don’t chafe when working.

Best underwear ever!

Having endured a lifetime of uncomfortable underwear, I was a bit skeptical at first that these would be any different. I was wrong! This boy and his boys love, love, love our Krakatoa underwear!!!

Sleek and supportive

Both the trunks and boxer briefs are a perfect balance of soft sleek profile and excellent support where I want it. They move with you and make a clean line under even form fitting active apparel; the front pouch offers support that keeps chaffing at bay without feeling constricting. I’ve been an avid wearer of Saxx and exofficio give-n-go for years and these match if not surpass those in performance; Krakatoa has become my go-to in terms of comfort and style. In a fairly saturated field of new performance minded undergarments, they certainly stand out as a top choice. I will be adding a few more pairs to my regular rotation soon; I couldn’t be happier.

Super comfortable. Definitely one of the best brands I've tried, and I've tried a lot. Excellent customer service as well. Highly recommend.

Fantastic underwear and supremely comfortable

Was really surprised at how great these were. Only downside was I thought the boxer briefs were too long in the leg. Shorten them up a couple of inches and they would be perfect. The trunks are amazing. They don't ride up like I've see others. Everything conforms to your body and holds it all together while keeping the berries separate.
