Women's Apex Bib Liner

Size & Fit Chart

OVERVIEW: Every inch of singletrack is meant to be enjoyed, and the women's specific Apex MTB Bib Liner ensures you'll have unencumbered, all-day comfort. Built from the foundation of our award-winning Ascent Vector Bibs, the Apex features the same endurance chamois we utilize from the Italian-manufacturer, Elastic Interface®. When temperatures rise, the mesh body fabric provides cooling breathability. A rear double pocket system not only includes an elastic retention strap for your pump, but on the body storage for a jacket or full-size water bottle so you can ditch the hydration pack during those 1-3 hour adventures.



 FABRIC AND CONSTRUCTION: Breathable stretch mesh cover the majority of the body for extreme moisture transfer and body temperature regulation. Avertini lycra is used in the rise for increased durability and structure. The double pocket system built into the rear allows for on-the-bike access and storage that will not press against your spine while riding. The MARC 45mm legband incorporates a thin silicone strip to stay in place while pedaling. The multi-density Elastic Interface® Endurance 2 Carbonium chamois offers 4+ hours of comfort and includes carbon threaded, anti-microbial fabric.

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.
