Bought these for my partner
Bought these for my partner and he loves them! Really loves the fit, pouch, horizontal opening and the soft material! He looks great in them. Started with a medium which he can fit into but really likes the comfort of the roomier large.

Simply great product
I began with the purchase of a couple of items! Now Krakatoa are the only briefs I buy and I have many.
I am very happy to recommend them to everyone. You simply cannot do better with #1. The fit and the quality.
I am a customer for life!!!

Beyond comfortable. Your reviews don't lie.
I received my second shipment of Kratatoa Pinatubo Briefs because the first shipment from last month was so awesome. I bought a few pairs as a test and boy i was not disappointed. Great, comfortable fit - it feels like I'm going commando! Love the waistband which never folds over. I'm looking forward to enjoying these.

This is the brand for me!
I haven't been able to find another brand that has topped the offerings of Krakatoa! The new seamless adds the cherry on top of an already excellent product. Thanks for doing what you do.

Potato seamless briefs
I love the feel of the material. The soft fabric holds my goods in such a way that gives me comfort as I walk along. I was recently in Tahoe doing some hiking and the separation of the goods and thighs really made a wonderful experience. No chafing or hair pulling. The sweat seemed to be pulled away from the skin. Every morning I look forward to putting these underwear on. I now have several styles to select from in my drawer. Thank you Krakatoa

Great Fit
I was skeptical but when I received my first pair of the briefs I was pleasantly surprised. Amazing fit. Roomy to hold my goods comfortably. Will definitely recommend.

Freakin Fabulous
I have been sporting boxer briefs for many years and was happy with them until I wasn't! I bought one pair of these undies and boy howdy my junk loves them. I bought a whole weeks worth. And they are sexy AF! The ladies love the buldge.

More than what I expected
I hate respect what this guy is doing with his time and life constructing comfortable and safe healthy material underwear for us, men.
