Castelli Amplify Thermal Jersey 2026

Designed for cooler days, this jersey combines comfort, warmth and performance. Its mid-weight fleece fabric keeps the body warm whilst ensuring excellent moisture management, whilst the stretch sleeves offer optimal freedom of movement.

The main body, made from 3D fabric (93% polyester / 7% elastane), traps air to retain heat without compromising breathability. The side panels and sleeves, made from 80% polyester and 20% fleece, ensure a precise fit and superior comfort.

Practical and functional, it features an elasticated waistband, three spacious rear pockets for carrying your essentials, and a smooth, reliable YKK® Vislon® zip.
