Castelli Alpha Ros - Thermo JacketThis jacket comes very close to the goal of perfect functionality in dry conditions combined with protection in the rain. The use of the Gore® Windstopper® membrane, partially sealed seams and a waterproof YKK® Vislon® zipper has made it essentially waterproof without compromising in dryness.
Comfortable protection in dryness and rain: the Alpha Ros thermal jacket from Castelli
Until now, bike clothing was known to be suitable for either dry or damp weather. Hardly anyone would think of using rainwear in dry conditions. It just feels uncomfortable and not streamlined. The Alpha RoS jacket fills this gap.
The starting point was all the proven features of Castellis jackets: separate insulation and outer layer for individual temperature and moisture management control, excellent breathability, flat cuffs on arms and waist, split collar, comfortable materials and an excellent fit.
Castelli conducted tests in the most adverse autumn weather. A few drops of water penetrated into the interior. Nevertheless, you stay warm and dry because this jacket offers comprehensive weather protection and lets body moisture quickly escape to the outside.
