WHO ARE KRAKATOA TRUNKS PERFECT FOR?

The Anti-Gravity Trunks are perfect for active guys that prefer a little less leg length than our Boxer Briefs but aren't quite into Briefs, or for those of us that wish we were more active and equally enjoy the feeling of supportive, barely there, ultra-soft underwear.

Whether you're working out or just lounging around the house, these Trunks will materially change your life.

WHAT MAKES THEM KRAKATOA?

  • Feel softness like never before with an ultra-premium, hand selected 95% MicroModal fabric. We source only the best MicroModal because comfort is our #1 goal. (Learn about MicroModal). We then blend the MicroModal with 5% Spandex to allow for it to move with you.
  • Enjoy more room with a large front pouch that provides space and support for your cargo, with complete separation from your thighs. No need to adjust anymore.
  • Feel comfortable all day with a waistband that doesn't flip or fold.
  • And keep them longer with the peace of mind of our 52 Wash Guarantee.

WHAT'S GREAT FOR THE WEARER?

The Krakatoa Trunks are specifically designed for maximum comfort.
They work well for a variety of activities, from working out to lounging around, they can take on anything you throw at them. Once you make the decision to embrace this everyday luxury for your privates, getting dressed in the morning will never be the same again.

Great for: Walking, Hiking, Lifting, Exercising, Yoga, Lounging.

HEY ALEX, I HAVE QUESTIONS!

What should I know about the fit?

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.

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.

    Doesn't Get Any Better Than This!

    Finally, the perfect pair of underwear! Since trying the Anti Gravity and Haleakala Trunks, I'm sold. I have converted over to these for all daily wear underwear. Amazingly comfortable and full support while not feeling like you are wearing anything at all. No mid-day adjustments ever needed and no riding up. The legs stay put. I used to buy "higher-end" underwear but nothing compares to Krakatoa! I love them!

    Anti Gravity Trunks

    These are the most comfortable underwear I have ever worn. The material is soft and you barely feel like you are wearing any underwear. The waistband is so comfortable and lays perfectly on your waist without ever folding over. Best underwear ever made.

    Best underwear I have ever owned

    As a gym goer I have always dealt with wedgies and sweat making my underwear stick to me in ways I would rather not happen. These underwear keep everything in place, are breathable and my favorite part about them is the waistband is snug but doesn’t leave marks or feel uncomfortable. These are more comfortable than wearing nothing! Bought one more to try and now I have three more on the way.

    my girlfriend chases me around the house when I wear them

    Love the new trunks. Super comfortable and soft. The best part is my girl attacks me. My pishadeel looks better in these than any other underwear.

    Like a cool hug for my junk!

    These are hands down my favorite undergarments I wear! So comfortable I almost joined a boy band! I don't know how that applies, but they are inspirational! That's my point!

    Best trunks I own!!

    These trunks are super comfy and the material is super soft and fits everything perfectly! I usually wear a trunk or thong and I love both from Krakatoa! I am super happy and will definitely be buying more from them in the future! The fit is great and feels like I’m being supported and still feel like wearing nothing.
