About our trunks

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.

Comfy ,but rides up

The underwear are soft and comfortable definitely hold a package in place with some buldge, but they ride up I wish I would’ve gone with the longer ones.

Light Weight and Never Slips

These are so comfortable. The pouch gives just the right support without smashing everything. The waistband is wide and fits just right, so no slipping. I appreciated the offer of the giftKard toward another pair. Just ordered them today. I wish there were more color or pattern options? I’ll be replacing my old underwear with these!

Amazing fabrics

The fit is great, the pouch is ample. I’ve worn them 5-6 days with no binding, tightness—they really stretch.

Best Ever

My Krakatoa underwear are the best I've ever worn. I'm really glad I took the plunge with my initial order since I rapidly realized how good they are and order many additional pairs.

The best ever

I just hiked 300 miles on the AT wearing this underwear. They are by far the most comfortable underwear I've ever worn.

Best of several

I have tried various types, and one type is almost as good as Krakatoa. Let's say 7 out of 10 with these being a 10. I wish I could describe what it feels like to have these on. But then you might think some corporate person wrote a fake review. Just buy one pair ... and most likely you'll be buying more.

Amazing Underwear

I have been searching far and wide for the perfect pair of underpants, and my search is now over. I feel like a superhero wearing these, and so does my junk. Extremely comfortable and perfectly breathable.

Best pair of underwear that I own

I've been on a long search for the best underwear, since there are so many out there now and all with seemingly many of the same options. I like the extra space in front, the feel of the material and the fit. I'll be getting more of these when I need replacements.
