Description
Part of the Rain or Shine range, on the coldest, wettest days the softshell Castelli Alpha ROS Jacket will keep you warm and dry, yet is breathable and fast-drying for when the weather improves.
Windproof and waterproof thanks to the Gore Windstopper membrane, strong winds and showers are no problem for this jacket. The highly stretchable material allows you full freedom of movement and the multiple-layered construction optimises moisture management and ventilation with the inner layer providing extra comfort and insulation.
The smooth waist panel adds to the great fit and the silicone bottom hem keeps it lying flat for a sleek look. A full-length YKK zipper ensures you can unzip to keep you cool if necessary and the zip is partially covered for added protection from the rain.
Smooth cuffs allow you to comfortably wear gloves on those winter rides and three rear pockets provide you with all the space you need to carry all your essentials, with the added bonus of a security pocket with a waterproof zipper.
