    Love this thong

    Definitely the most comfortable thong I have ever worn. All I wear is a thong or jockstrap. I definitely recommend

    Brief shorts

    Absolutely the best ! Very smooth and comfortable to wear. Easy delicate wash able ! Wonderful material that makes you feel like you’re not wearing anything at all.

    Thanks for the amazing review, Anthony! You totally captured what the Aspire Zero Brief is all about – that smooth, weightless feel that makes you forget you're even wearing underwear. Love that you mentioned how easy they are to care for too; we designed them to maintain that incredible softness wash after wash. It's awesome that you're getting that "wearing nothing at all" experience – that's exactly the kind of invisible comfort we engineered into the Zero Brief design.

    2nd purchase

    After trying a few different styles, the zero brief fits well, and it has the required support for daily activities. One of the most comfortable briefs out there in the market.

    I’m not sure …… well, I’ll try them.

    Ok, I’ll admit it straight forward. A thong for a man ??? I’m an avid gym guy, working out 5 days a week. Biggest problem I have is my underwear either curls up at the leg(boxer briefs) or crawls, becoming very uncomfortable. After reading several reviews I decided to try these “just” to see . Well, I must admit I was a little surprised by the size of them upon opening the package. I did size down as several reviews suggested. Once I “adjusted” everything into position, they actually were very comfortable and I didn’t even notice them riding in my crack, LOL.

    Felt like I was wearing nothing at all, but my stuff stayed snugly in place on my run. Very comfortable at the gym, no stopping to look around and discreetly adjust and tug back into place. So , I can honestly say my thoughts on a men’s thong has changed 🤣. Trust me guys, try them and you want regret it, but size down , they really will conform to fit all your “stuff” comfortably.

    Thanks for the honest review, Jason! Love how you went from skeptical to converted – that's exactly the kind of transformation we hear about with the Zero Brief. You nailed it on the sizing advice too; going down a size really does help that fabric lock in and conform perfectly to your body. It's awesome that you're getting that "wearing nothing" feel while everything stays exactly where it should be during your workouts. No more gym interruptions for adjustments! That's the whole point of the Zero Brief design – giving you that invisible support so you can focus on crushing your training.

    Wow! The thong feels as though I am naked!

    Wow! They are thin, light weight, and skin tight, everything I was looking for. They will be my "go to" during the hot summer months. Sizing is accurate. At the current price point, I will probably buy just one more pair.
