The Circuit short is perfect for your everyday training runs. We've updated the fabric to MicroLite Stretch™. It offers a security pocket so you don’t lose your key and two drop pockets for your energy gels during those longer runs. The lightweight short dries quickly and the soft, 4-way stretch boxer brief liner offers chafe free running and moisture wicking management.
Fabric: MicroLite Stretch (92% polyester, 8% Spandex)
Liked the circuit short with the original fabric. Noticed the new fabric when I went to the Sporthill site after getting a sale e-mail. Ordered a pair with the microlite stretch fabric. Have worn the shorts for a couple weeks in Texas summer weather - sweat-soaked at the end of an hour-long workout. The new fabric is great. If you need/want to, you can comfortably wear a compression short under the Circuit Short liner.
Thank you SportHill , very happy with this product for my summer runs and i have secure pockets for my keys.
