The 7mesh Tantalus Long Sleeve Jersey pairs WTV 200 fabric with a Skin Fit cut that follows the body through every position on the bike. The thermal layer holds warmth on a cold descent without trapping heat on the climb back up, so a single ride's temperature swings stop being a wardrobe problem. A fleece-lined collar and chin guard block wind at the neck, and an elastic hem with a silicone gripper keeps the jersey in place when the effort picks up. What Our Gearhead(R) Experts Are Saying:"I started a ride in shorts-and-jacket weather and finished it in a headwind that dropped ten degrees, and the Tantalus never asked me to add a layer. The WTV 200 fabric shed the wind at speed and still breathed enough on the climb that I never unzipped."
