Consider the GORE BIKE WEAR Xenon S jersey to be the ultimate lightweight climber's jersey. The fit is close, truly like a second skin and employs sonic welded seams that lay completely flat, as if the entire jersey is one panel. Strategically placed mesh panels and breathable mesh back keep airflow high to keep you cool. The thoughtfully detailed ergonomic collar further reduces irritation. Other details include 3 angled rear pockets, a zipped security pocket and a full-length locking zipper.
