The Sense Softshell Jacket puts adv. WIND(TM) protection and a DWR water-repellent finish on the front panel, where wind and rain hit first, while a brushed jersey back panel stays breathable so heat doesn't build up underneath. The softshell material carries light thermal insulation for medium warmth, cut in a slim fit that moves with the body instead of adding bulk. What Our Gearhead(R) Experts Are Saying:"I ran straight into a headwind for the first three miles and never felt it cut through the front the way it usually does in a plain shell. By the turnaround my back had vented enough heat that I wasn't peeling layers at the car."
