Size & Fit Chart Need Help?    
Race semi form fit cycling jersey

 OVERVIEW: The lightweight and super-breathable Apex MTB jersey has been created to perform exceptionally well in a variety of conditions. Whether climbing or descending, or bombing along some singletrack, we wanted to develop a garment that could be paired with or without a hydration pack and would provide lasting comfort on any trail attacking adventures.



PAIR WITH: Pair with our Apex MTB Short, offering the same performance-minded minimalism. Also, pick up a pair of our Apex MTB bib short liners to keep you comfortable each hour spent on the trail. The Apex Bib Short Liner features our Ascent level Cytech E.I.T. Liege Carbonium chamois and unique rear pocketing system to allow you to ditch the hydration pack on those 1-3 hour adventures.

FABRIC AND CONSTRUCTION: BreathLITE fabric is used in the rear body and sleeves to achieve optimal breathability and moisture transfer whether wearing a hydration pack or not. The soft, silk-like feel of the Run-Lite fabric used in the front body panel and neckline provides soft, abrasion resistant comfort. Both the BreathLITE and Run-Lite fabrics feature a tough snag-resistant resilience. The seams on the shoulders have been shifted forward to avoid a potential pressure points when used with a hydration backpack. The Apex Jersey offers a contoured design for a slim body-shaping fit.


  • BreathLITE fabric in the rear panel and sleeves
  • Run-Lite fabric in the front body
  • Slim contoured fit
  • Necktape covering the rear collar seam

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.
