Peal Izumi knows that conditions are subject to change and that layering is key when it comes to cycling. The Transfer Mesh Sleeveless Baselayer is designed to be utilized as a layering tool, and it regulates body temperature through moisture control to keep us comfortable while we're riding. PRO Transfer Mesh fabric is employed with In-R-Cool for improved thermoregulation so the base layer can be used on its own, under a jersey, or as a shoulder season layer. GoFresh anti-odor technology ensures we'll stay fresh even after a grueling training session.
