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 base liners you have a choice of three fabrics and four lengths.
  • This allows you to dial in a base liner based on current weather conditions and personal preference.



The flex is in the spiral yarn. This configuration gives the fabric a built-in mechanical stretch that goes to all 360 degrees of adventure. Thanks to this technology, the fabric will stretch and recover without using heavier water-absorbing elastics like Spandex. Upshot: outstanding breathability, abrasion resistance and a softer feel against your skin. All this at 40% the weight of the old school stretchy stuff. PrimeFlex is both eco and techno. The fabric is partially made from a corn-based material that uses less water during processing. There’s comfort from mile one to mile one hundred.


Tripure is a high tech nano fiber that delivers incredible comfort and performance. The Benchmarks are superior stretch and recovery and fined-tuned temperature regulation. Dries quickly, anti-microbial, static free and durable beyond all normal expectations. The humble waistband gets its 15 minutes of athletic fame.


The Classic fit is tailored, but not too tight. Built for most body types.
