No roll waistband and amazing comfort!
I love these underwear!! They are incredibly soft and comfortable and not binding even though I've put on a few pounds since I started wearing them. But, the greatest thing about these underwear is that the waistband does not roll over AND it's still comfortable, my stomach roll doesn't roll it down. This was what I was looking for! I just ordered 4 more pair. I can't wait until my whole underwear drawer is filled with Pinatubo from Krakatowa. Thanks for creating an amazingly comfortable garment.

I Love Pinatubo Style!
With all of the Krakatoa underwear that I have bought, I’ve learned that Pinatubo is the best style for me! Absolutely LOVE every Pinatubo model I have purchased! From the trunks, to the thongs and the others in between, Pinatubo are the BEST! The comfort of the material is so soft! The size of the pouch is perfect for me! The horizontal fly is the easiest access when needed! I have exclusively changed my underwear drawer to Krakatoa!!! Nothing else compares to these underwear, NOTHING!
Thanks for creating such a wonderful product!

Best underwear in my 60+ years on this planet!
The fabric is amazing. It is soft, movable and breathable the fit once I asked for help with your sizes you helped me out right away and it is probably one of the best fits I’ve ever had now for the features. The ball pouch works like no other and believe me I have the ones with the flaps. I have the ones with other features. Nothing works like this. I am very glad I got these. They are in heavy rotation and as soon as I can afford some more. I will get some more thanks!

Luxurious comfort... superb support!
I can't rave enough about these Pinatubo seamless sports boxers! I've been pretty dedicated to either Under Armour or Tommy Johns for several years, but got so frustrated at how the sizes never stayed consistent, nor the same fit. But these (3rd ordered now...) have the best balance of comfort & support I've ever worn! The material is luxurious and sexy - maybe little too much, as I'm aroused a bit every time I think about how perfect the boys are nestled in place. The fly is THE perfect design for many reasons 😉
Keep up the good work guys!

Best underwear ever!
I came across this company and these underwear and figured I’d give them a shot. I’m glad I did! These are the most comfortable, most natural feeling underwear I’ve EVER had! The elastic waist is wear all day comfort. The material moves with you in every way and the best part is how these underwear takes care of your boys. No more awkward shifting, no more sticking to the side of your leg, all day comfort where it counts! If you’re on the fence about these, don’t hesitate and get yourself a pair, or 10 like I did! You will not regret it and your boys will thank you for it!

Best underwear EVER!!
I’ve always been a boxer guy. Needed room to breath if you know what I mean. Always found regular boxer briefs to be extremely uncomfortable because of the legs riding up. These underwear solved that problem. Will never wear another brand of underwear. Thanks for making an extraordinarily comfortable product!

As advertised
Never had it so good! Everything came through as advertised. Roomy, comfortable, no chaff pouch is a game changer and the horizontal escape hatch is clutch. I bought 10 pairs but gave one to each of my twin sons as possibly the most “unique” gift I’ve ever given them. They immediately became “raving fans”. I’ll be purchasing more for me and many more for them.

Phenomenal!
I bought these because I wanted to get away from the polyester fabric. I never cared for cotton because it isnt moisture wicking and once they stretch that's it, done. These boxers cover all my needs all while being made of natural fibers!
