What Our Gearhead(R) Experts Are Saying:"I have been running in the Pace Hybrid Full-Zip Jacket through some genuinely ugly winter weather, and the 4-way stretch storm fleece construction keeps up with every stride without any restriction. The watch-compatible cuffs are a small detail that I now expect from every running layer I own, and the reflective details on the back and sleeves have given me real peace of mind on early morning efforts before the sun comes up."The gap between a brisk fall run and a hard winter effort is narrower than most people think, and the Swix Pace Hybrid Full-Zip Jacket bridges it without asking you to carry an extra layer. The 4-way stretch storm fleece construction moves freely in every direction through every stride and arm swing, while the brushed interior elastic panels add a layer of warmth against the skin that you feel immediately when the temperature drops. On cooler days, it works as a standalone outer layer. On colder ones, it layers cleanly under a shell without bunching or restricting movement. Thumbhole cuffs keep sleeves locked in place and give you easy access to your watch. Reflective details on the back and sleeves keep you visible when you are pushing through low-light conditions, and a zippered chest pocket secures the essentials you need on a long run without bouncing around. The Pace Hybrid Full Zip Midlayer is the layer that makes cold-weather running feel less like a compromise and more like a choice you are glad you made.
