The first minutes of a run call for warmth, and the elastic panels on the Swix Focus Vest hold it in with a brushed interior that still stretches with every stride. A storm placket with a chin guard shields the neck from wind, and an elastic hem keeps this running vest snug. The zippered chest pocket keeps small essentials within reach. What Our Gearhead(R) Experts Are Saying:"On harder efforts, I opened the ventilation tab at the back and heat left before it built up. The vest stayed comfortable through the easy opening miles and the faster finish alike."
