Price displayed is price-per-garment for a 5 garment minimum order. See Price List for additional pricing options and currencies.

Every inch of singletrack is meant to be enjoyed, and the 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.

Pair with our Apex MTB Short, offering the same performance-minded minimalism.

This item cannot be customized and is available through the Official Pactimo Shop as a complimentary piece for your custom Apex Shorts.

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® Paris chamois offers 4+ hours of comfort and includes carbon threaded, anti-microbial fabric.
