Gym Girl Skirt

It all started on a training run in 2004… 

In early 2005 at a marathon expo in Austin, TX, this skirt launched the Skirt Revolution as the first skirt targeted toward runners with built-in shorts that didn’t ride up. The first prototype was made from silky, quick-dry swimsuit fabric that I found at a closeout mill, with lightweight nylon/spandex mesh shorties & a drawcord that used a lace lock to stay in place. I tested the skirt during long Ironman training runs on and around the trails and roads of Boulder County. While the prototype was rough, I knew I was onto something. Even at the 3 hour mark, my thighs were chafe-free & I literally forgot I was wearing a prototype. That became my new standard for wear-testing. If I didn’t think about the product, the sample was a winner!

For 20 years, the Gym Girl has remained our #1 seller because it checks all the boxes: not too short, not too long, shorts that land just over the thigh-hump, a mid-rise waistband that hits near the belly button on most torsos, two pockets & a drawcord so it won’t fall down even if you load up the pockets!
