The Zip Tri Jersey is a great piece for longer triathlons. It offers shoulder and back coverage from the sun. It is made of nylon spandex and is supposed to be worn skin-tight for aerodynamics. It has a longer 12-inch zipper that goes high up the neck to eliminate wind drag while on the bike in the aero position. The body has a more comfortable fit, and new Liquid Mesh side panels and side pockets. This mesh on the sides will offer a lot more ventilation and breathability over other similar tops on the market.
