ASSOS S.J. Blitzfeder Switzerland Cycling Transparent Shell Jacket Trikot SMALL

The rule used to be, start with the shell on, but take it off after warming up and before you start sweating. The rule can now be broken, thanks to the Assos SJ.BlitzFeder Long Sleeve Shell. The fear was that once you started sweating, the shell wouldn't breathe, and your baselayer and jersey would be soaked through. Then once you unzipped the shell, you'd freeze.No longer. This long sleeve shell is made of Assos' new Foil043 fabric. It's feathery light, a claimed 96g for a size medium shell. It's ultra-thin; ball it up and it easily fits in a jersey pocket without sticking out. There's even a stuff sack sewn into the jacket. Assos calls the material a 'natural windbreaker,' which is their way of saying that there's no membrane creating the windproof qualities of the material; the structure of the threads and the density of the weave make it so. A treatment is added to give the fabric water repellency. And, as Assos cares about aesthetics, this fabric was engineered not to rustle in the wind. Assos claims that the value of waterproofing is overrated in many riding conditions. See more in photo… 5 1137
