Amplify Thermal Limited Edition Jersey - Men's

What Our Gearhead® Experts Are Saying:

"I’ve ridden this jersey in everything from foggy mornings to windy descents, and it punches well above its weight. The brushed inner fabric really holds warmth, but the sleeves breathe well so I don’t overheat. The fit’s dialed—tight where it counts but still comfortable on long climbs."

The Amplify Thermal Limited Edition Jersey is a shoulder-season essential designed to keep performance high when temperatures drop. Its fleece-lined main body is constructed from a 3D knit fabric that blends 93% polyester with 7% elastane, effectively trapping warm air while providing exceptional moisture management. The sleeves and side panels are made with an 80/20 polyester-to-fleece blend that adds stretch for improved comfort and mobility.

A regular fit supports layering versatility while reducing aerodynamic drag. Functional details like three rear storage pockets, a gripper elastic waistband, and an easy-sliding YKK® Vislon® zipper add ride-ready utility. The jersey is best suited for cool-weather efforts in the 57–64°F (14–18°C) range, bridging the gap between deep winter gear and summer-weight kits.

Whether you're racking up base miles or chasing early-season segments, the Amplify Thermal Jersey offers the warmth, comfort, and technical precision needed to stay out longer and push harder.
