Endura Windchill Jacket II Light weight, waterproof protection. Endura have updated their wind-stopping Windchill jacket for an even more effective waterproof & windproof outer shell. Now it's called the Windchill II, which is very imaginative. Perhaps instead of thinking of a new name Endura put all their energy into designingthe versatile fit of the waterproof, windproof & breathable stretch fabric on the front & sleeves, the Roubaix lined underarm, side & back panels, the functional zipped pit vents & handy rear pockets. Excellent versatile top layer. Wear over a jersey when it's a bit chilly & over a jersey, base layer & fleece when it gets proper cold.
