Briefs guy becomes trunks guy
I liked your briefs product line so much that I decided to experiment with the trunks line. I had no experience with trunks and was concerned about leg feel. Fortunately I watched several of Ishi’s instructional videos. I knew what to expect and how to adjust to my perfect fit. The fabric is the same as I was familiar with. That same stretchy quality giving lots of support. The trunks are supremely comfortable.
My only complaint is with the stone color. I absolutely love the Stone color in the Dominate line. It is rich, subtle, and tinged with a faint amount of green. A positively gorgeous color. In the Aspire line it’s just a boring grey. I will not be ordering that color again.

Simple and Comfortable
Incredibly thin and comfortable, you barely feel like you’re wearing anything. At the same time, everything stays comfortably supported and in place. It’s basically like being naked, but with everything where it should be.

Well worth it
Didn't know what to expect when I purchased these and was surprised when they arrived. They are super light but great quality and an amazing fit. Only bought one pair but now I am convinced to purchase more.
