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:

INDEPENDENT SUSPENSION 

  • 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.

PERSONALIZED PERFORMANCE

  • 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. 

Technology

TORAY AIRTASTIC ™

TORAY AIRTASTIC™ Airtastic™ is a super lightweight and very high-performance nylon material. The compact mini ripstop weave of the fabric adds strength in the most efficient way possible, without adding excess weight. The flex properties in the yarn are achieved through the use of innovative spiral spinning technology, that give it mechanical stretch without the use of heavier, water-absorbing elastics like Spandex. It is also highly breathable, moisture wicking, water repellent and very quick drying.

TRIPURE™ ELASTIC

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.

We hacked running shorts

We split the running short in two: separating outer shell from base liner. The short moves without shifting the base liner, eliminating all chafing.
