          The TBô Black Trunk is cool and comfortable

          The TBô Black Trunk is cool and comfortable. Perfectly suited to the atrocious summers in the place where I reside. Also, it is good to wear something made to fit a human man, not a shop dummy.

          average.

          They fit well. The pouch was ample. Disappointed in cold choices. I personally like white or gray. Hate red followed by black. While the pouch was ample for room it has no structure. You hang like a potato sack. Material is soft and absorbent a good thing. Keeps you from chaffing against your legs. I feel like an average effort into design, but I am above average in my build and my expectations I. My underwear

          Great product!

          I absolutely love these trunks! The fit is great, the pouch really accentuates the bulge, and (as many waiters can tell you), "crotch rot" is a thing of the past! I had never heard of bamboo fabric, but apparently it has great moisture wicking capabilities, so sweaty balls aren't a problem anymore!

          Sweet Trunks

          Love, love, love my TBo trunks. So light weight and so comfortable it's like you're not wearing anything at all. Love the way the look too! Have received several compliments from friends! 😉
