Assos EQUIPE RSR Jersey SUPERLEGER S9Incredibly light and incredibly breathable, the Assos EQUIPE RSR Jersey SUPERLEGER S9 has been created for the demands of intense hot-weather races and hard training, both indoors and outdoors.  You Won't Know it's ThereThe EQUIPE RSR Jersey SUPERLEGER S9 weighs in at a barely noticeable 82 grams (size medium). First ridden as a prototype at the Tour de France and subsequently refined via rider feedback at World Tour races, this is a jersey unashamedly focused on low-weight performance for the hardest of races and toughest of training efforts. Extreme PerformanceThe most noticeable feature, after the weight, is its open-cell, zipperless design. Made with Hill Rombo, the lightest textile they've ever used for a jersey, it allows for impressive levels of breathability when the heat is high and you're sweating profusely - think tarmac-melting temperatures of summer racing and indoor turbo sessions.  The open-cell material also allows plenty of air to reach the body, speeding up the cooling effects of sweat evaporation. Assos also deploy superlight mesh for rear pockets, again reducing grams and boosting moisture management.Fit for SpeedBe it jostling for position in the peloton or making the break, the figure-hugging racingFit offers unrivalled aerodynamic efficiency. Assos has also removed the zipper, enhancing those gains and giving a smooth fit when in an aggressive riding position. Built for the WorldTour it's a jersey to benefit all cyclists with an eye on performance. Raw-cut sleeves eliminate ridges over the biceps, giving a smooth leading edge to the jersey. Assos has also removed any tape at the ends, giving a true lie-flat finish. Features:Materials: 78% Polyester, 14% Elastane, 8% PolyamideSuperlight and breathable Hill Rombo textileDesigned to be worn without a base layerRaw-Cut Sleeves eliminate transitional ridges on the sleeves for improved aerodynamicsZipperless designSingle Pocket - larger than a standard jersey pocket to hold phone, gels, and a wind vestAssos racingFit - built for the WorldTour, so no start line is beyond its scopeWeight: 85 gramsAssos Recommend applying sunscreen beneath while wearing this jersey outsideBuy Assos Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
