Part of the ROS (Rain or Shine) family, Castelli's Women's Nelmezzo ROS Jersey is brilliant for cycling in cool, dry weather but if your bike ride takes you through rain showers the excellent water-resistance will keep you comfortable.

The Women's Nelmezzo ROS Jersey is Castelli's do-it-all spring and autumn cycling jersey. A double layer fabric, Nano Flex Xtra Dry outer and polyester inner, work in harmony to keep cold winds out and body warmth in. Because there's no membrane the jersey is also brilliantly breathable, far more so than a traditional windproof top, and so harder training efforts won't leave you a damp, sweat-soaked mess. The tight weave of the Nano Flex Xtra Dry also has another key benefit, it's virtually waterproof, making wet roads and damp misty conditions nothing to fear - for heavy rain you'll still want a hardshell rain jacket but this jersey extends the time before you need to pull one on. 

An easy-sliding YKK® Vislon® zipper makes control of ventilation quick and easy and with 3 rear pockets you've got all the space you need to keep fuel for your ride. Castelli also adds reflective details to boost visibility for those rides that finish as daylight fades.

A brilliant all-rounder, the Women's Nelmezzo ROS is your do-everything cycling jersey when conditions are hard to predict. Warmer than a normal thermal jersey but more breathable than a windproof jacket it's just what you need for cold starts, chilly days of changeable weather or fast-paced winter rides.
