PEARL iZUMi

Attack Thermal Jersey - Men's

What Our Gearhead® Experts Are Saying:

"I use the Attack Thermal Jersey all fall and early spring—it layers great under a shell and breathes well enough to keep me from overheating when climbing. The fleece is soft without adding bulk."

The PEARL iZUMi Attack Thermal Jersey is our go-to for those brisk mornings when the sun’s out, but the chill hasn’t quite lifted. Designed to strike the perfect balance between insulation and breathability, this cool-weather staple features a lightweight thermal fleece with grid channels that wick away moisture and stretch effortlessly as we shift and climb. Whether we're hammering solo training miles or riding tempo with the group, the jersey keeps us warm and moving freely.

With three rear pockets plus a secure zippered side pocket, there’s plenty of room for nutrition, tools, and even a phone. BioViz® reflective elements keep us visible in low light, and the UPF 50+ rating gives us a little extra peace of mind on sunny shoulder-season days. It’s the perfect piece for cool rides—or as a critical midlayer when winter rolls in.
