The 7mesh Seton Long-Sleeve Jersey uses proprietary WTV construction to manage big temperature swings on a single ride: a stretch-woven, wind-blocking exterior pairs with a high-loft brushed interior that traps warmth on a climb and releases it on the way back down. A recycled-polyester blend and a raised collar round out a jersey built for cold, dry road and gravel days. What Our Gearhead(R) Experts Are Saying:"I've started a climb cold enough to second-guess the jersey, then hit the descent without ever feeling like I overheated on the way up or froze on the way down. That balance is the whole point, and it holds."
