Assos sJ.blitzFeder Jacket

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.
