While we're still waiting to see if Froome is clear to flyat the grand tours, getting shepherded through the mountains by the likes ofthe cousins Henao and Geraint Thomas, one thing is for certain--on the veryimportant mountain days in the heat, the squad will don the Men's Team SkyClimber's 2. 0 Full-Zip Jersey. Now you too can sport the same jersey thehighly-successful team wears that's suited particularly well to double-digitgradient climbs that go on and on while the sun relentlessly beats down itssweltering rays on the cyclists below. Castelli uses Flusso 3D mesh fabric along the front andshoulders to keep it light and airy and it rates the jersey's ideal temperaturerange between 72 and 104-degrees Fahrenheit. The material remains impressivelystrong, despite being so lightweight and its capable of handling some heavyrotation during the dog days of summer when any other jersey would just be toostifling. With climbing comes descending and motoring along in thevalley floors, so it's no surprise that Castelli bestowed some aero elements tothe jersey and patterned it after its Aero Race 5. 1 Jersey. Differences inmaterials mean that the Climber 2. 0 is only 2 watts slower in the dragdepartment, something that we think is well worth it when you're trying to staycool on your local climbs when turning the pedals in anger.
