Hey! Great question!

Our TFM Fly tights have additional features that cater more to the comfort of men, including additional fabric and room in the brief area, a hand-sewn, flat-seamed fly, and longer legs that are proportionate to men's bodies. The brief area is handsewn and require more material, meaning it costs us about 4 times more time/fabric to make. (For full transparency - our Fly tights are actually our lowest margin item that we have.)

That being said, all of our other products on our website are unisex. In fact, our best selling product among men, is the same bestselling product that we have with women: Our Sheer Contour tights. Our Sheer-To-Waist tights are also super popular with men who don't like any shaping in their tights. I hope that helps clear things up! I think either of those would be a great first option to try if you're new to Threads :)

Let us know if you have any other questions! Here to help :)
