While Zoic's Carbon Bib Liner doesn't actually use carbon, it does rock an Italian-made 3D Elastic Interface chamois that helps your undercarriage stay comfortable over chattery rock gardens and high-speed descents. It's designed to be stretchy, moisture-wicking, and anatomically-padded, with different foams in different places for extra comfort and an ergonomic profile made for long days in the saddle. It's clear that the Carbon Bib Liner is engineered to maximize comfort and minimize irritation, what, with seamless straps up top for a ventilated, chafe-free fit, along with a lightweight mesh mid-section for no-sweat support. Zoic finished this liner off with Stow & Go convenience--first, stow all your gear in the ample storage of integrated pockets and ditch the pack, and go when nature calls and relieve yourself quickly with the easy-access horizontal fly.
