Using extensive design input from two time Olympic champion Anna Meares, the Santini Women's 33 Aero Jersey spares no expense at delivering aerodynamic efficiency, breathability, and microcirculatory stimulating performance. Its aerodynamic cut closely follows your body contours, much like a second skin, helping to reduce drag when you're riding at high speeds. BCOOL back panels enhance breathability by channeling cooler outside air over your back, courtesy of its circular cut outs. Moreover, you'll appreciate the jersey's three rear pockets, which provide ample storage for nutritional supplements and extra layers. Perhaps most impressive with the 33 Aero Jersey is its Resistex Bioceramic fabric. This fabric consists of polyester fibers bonded with bioceramic material for excellent thermal insulation, regulating your core temp during cooler rides. It also acts as a natural barrier to harmful UV A and UV B rays when you're cycling under the bright summer sun. Furthermore, Resistex Bioceramic fabric has the ability to reproduce far infrared rays FIR that are emitted by the sun. This provides numerous benefits to cyclists by stimulating the microcirculatory system blood flow in smallest vessels. The heat generated by FIR also provides enhanced tissue oxygenation and eases the relaxation of contracted muscles.
