Separate Shorts & Base liner system

All Path Projects 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 two fabrics and four lengths.
  • This allows you to dial in a base liner based on current weather conditions and personal preference.

Technology

TORAY PRIMEFLEX™

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™ 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.

Reviews Summary
Customers say these running shorts are comfortable and lightweight with excellent pocket storage for phones, gels, and keys. The back phone pocket holds devices securely without bouncing, while three zippered pockets provide ample storage space. Many appreciate the high-quality fabric that doesn't bunch up during runs and the separate liner system for preventing chafing. Common feedback includes praise for durability and construction quality. Some users note the shorts run tight and may require sizing up, while others mention the lack of traditional side pockets. A few find the fabric initially stiff but report it softens with washing.

    Best Running Shorts Ever

    This is my third pair. Can't think of another pair I'd want for hard days, easy days, or race days. I'll be back for more....

    Race-Ready Comfort

    I’ve been training for a half-marathon and also raced in the Path Projects Sykes PX Shorts, and they’ve been excellent from start to finish. For reference, I’m 5’8”, 135 lbs, and I went with the 7” inseam in a size small. The fit is spot-on—secure without feeling tight, and just the right length for both training runs and race day.

    I paired these with the Path Projects Lynx PD Liner (5” inseam, size small), and together they handled everything I needed. One of the standout features is the pocket system. The pockets held my gels firmly in place with no bouncing or shifting, even on longer runs, which made fueling much easier. I can even fit my iPhone 15 Pro Max in the back center pocket.

    They’re incredibly lightweight and comfortable—honestly, you barely notice you’re wearing them. I also experienced zero chafing, which is huge, especially during higher mileage weeks and on race day.

    Overall, this setup is reliable, well-designed, and performs exactly how you want it to. I’d definitely recommend these to anyone looking for a pair of running shorts they can wear with complete confidence, whether for daily training or race day.

    Comfortable with great storage

    These shorts are comfortable and the pockets - for phone, gels, portable cup - let me ditch my belt. They are nice. I ordered Medium, my normal waist is 32/33 depending on the brand.

    Sykes PX for the Win

    This is my second pair of these shorts. The first pair lasted and endured many years of trail abuse. The zippered pockets in back are great. Large pocket securely holds a cell phone and does not bounce when on the move. The two smaller pockets are each large enough for 3-4 gels.

    Comfort for miles

    Got these (and the Lynx liner) not long before my first 50k run. I wasn’t in love with anything else I had past about 20 miles so just went with it. No chafing. A little handy storage. Worked great.
