The Mavic Gennaio women's winter jacket is one of our favorites thanks to a very nice cycling fit and classic styling. We find the Gennaio will keep you warm and comfortable in a wide temperature range from slightly below freezing up to about 50ºF which is the majority of most folks' cold-weather riding conditions.
Most of the jacket is constructed of a medium weight wind-blocking material with a fleece lining. For effective temperature and moisture control, Mavic includes a more breathable material in the areas prone to heat built up - under the arms and across the back. Each arm has a zippered vent so you can induce a bit more airflow when things warm up or close them tight if things get chilly.
A nice addition this year is three external back pockets so you can reach for gels, blocks or bars in mid-pedal stroke. An Ergo Zip refers to an offset zipper that improves comfort in the neck area while sealing in the warmth. The Gennaio has an excellent fit with a long back and long arms. Ergo cuffs make for a perfect glove/jacket interface.
