Insanely Anatomical High performance riding gear that fits like a second skin. Made by interweaving head-turning styling with more than fifty years of Pearl Izumi apparel technology tailored to fit every curve, every line, every nuance of the greatest machine the world has ever known: the human body. Reaching out to new dimensions with the ergonomically formed outline of the new 4D chamois within the Octane Short and Octane Bib Short.

The 4D Chamois consists of 78% Micro Polyamide, 2% Carbon, 20% Lycra (thats lots of stretch for a chamois) and features all benefits of carbon yarn such as thermoregulation as well as anti static to maximize efficiency and reduce fatigue. Created from multi-density foams strategically placed for comfort and endurance, but not just layered, but assembled like a puzzle in pieces with no glue. The situation of the padding is based on extensive anthropometric studies (the measurement of bones). Under the sit bones is a 110 density perforated open cell foam. Under that layer (on top of saddle) is 80 density open cell foam. A better posture on the bike improves O2 consumption, so for road biker this does just that. Channeling in front alleviates pressure and allows blood flow. The 4D Chamois is elasticity in length and stretches where needed. It even becomes more breathable with frequency of washes.

P.R.O - Transfer fabric provides superior stretch and recovery with optimal compression and moisture transfer.

Ultra-supple Direct-Vent upper bib with superior stretch and recovery for perfect fit on or off the bike.
