Separate Shorts & Base liner system

All PATH shorts are unlined. For the best performance, pair with one of our base liners.

Here are the advantages of our separate short and base liner system:


  • The base liner stays in place and wicks away moisture. 
  • The short rides on the base liner and can move during a run without rubbing against your skin. 
  • This virtually eliminates all chafing.


  • With our baseliners you have a choice of three fabrics and four lengths. 
  • This allows you to dial in a baseliner based on current weather conditions and personal preference. 



Developed to perform from mild heat to the highest temperatures of summer. Our Flowthru FX fabric provides unmatched ventilation while it wicks away moisture and protects you from chaffing. A polyester and spandex punch hole knit high performance mesh. So soft and comfortable you can wear them for any sport or activity.
