The Short Sleeve Barrier Baselayer uses a proprietary, next-to-skin windproof front panel mated to Pearl Izumis P.R.O. Transfer fabric with Minerale™. This unique combination of fabrics creates a baselayer that keeps the riders chest warm but still wicks moisture away from the skin. This keeps the rider warm and dry in a wide range of temperatures. The Pearl Izumi Barrier Baselayer retails for $70.00. For more information visit www.pearlizumi.com.
