The Castelli Mortirolo 6S Jacket lies at the less severe end of Castelli's winter range. It is intended to take the edge off dry, cold mornings and allow warm-blooded cyclists to ride without overheating.

The upper chest and sleeves of the jacket are constructed from windproof yet breathable GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric, which has a fleece liner for added softness and warmth, while the lower body is made from thinner GORE-TEX INFINIUM™ WINDSTOPPER® fabric.

Meanwhile, the back is constructed from a more breathable fabric with no windproof veneer, which allows moisture to escape freely. This combination of wind proofing at the front and breathability at the back helps you to maintain a stable core temperature in cool weather, regardless of your activity levels.

Finished with a reflective panel at the chest and useful pockets, the Castelli Mortirolo 6S Jacket is minimalist and will keep you pleasantly warm on a fine winter's day.
