The season turns and most riders head indoors. The Women's Attack Thermal Jersey is for the ones who don't. It's a women's long-sleeve thermal cycling jersey that keeps the heat in and the pace honest when the mercury falls. The engine is a thin geometric grid fleece : it locks warmth against the skin and wicks sweat outward at the same time, so you stay dry and even through hard efforts and long winter miles. Breathable stretch fabric flexes with every pedal stroke and sits clean under other layers. Wear it on its own when mornings bite, or slot it in as a mid-layer beneath a vest or shell once the cold sets in for good. UPF 50+ guards your skin against low-angle winter sun. Every detail pulls its weight. Low-profile cuffs and hem trim the bulk for a fit that stays dialed in motion. The semi-locking YKK® front zipper holds its position over rough road and opens easily to vent on a climb. Three rear pockets carry fuel, tools, and a packed layer without shift or sag. Premium 3M BioViz™ reflective detailing keeps you visible at 100 meters when daylight fades, and with 89% recycled polyester in the build, a lighter footprint is built in. Cool-season regular. Deep-winter layer. In the rotation from the first frost to the last. Ride through the cold. Don't carry it.
