Women's Alternative Insulated Jacket
Lightweight insulated jacket with a narrow racing cut made from recycled materials designed for high-tempo rides in cold and dry weather conditions.
The front, shoulders and top of the sleeves are made from functional Pertex® Quantum Air material and feature a Polartec® Alpha® Direct insulation layer underneath. The composition of the jersey is complemented by high-density recycled fabric on the back and inside of the sleeves to prevent unwanted heat leaks. Polartec® is quick-drying and features excellent breathability and light weight. In addition, the outer layer is treated with a Fluorine-free water-repellent treatment, which increases the material’s ability to repel water and dirt. Three spacious back pockets are complemented by a zippered pocket and a zippered chest pocket for added security and accessibility of carried contents. Sustainability principles of the jacket production are underlined by two-way recycled zippers, zipper pullers and silicone tape around the bottom hem for better insulation, which is also made from recycled material.

Love it!!
Wore this jacket for the first time today. I was very happy with it! Wore it in 33°F for 2+ hours with a mid weight merino wool base and a merino wool neck gaitor. I never felt uncomfortable at any point during my ride. It didn’t feel weighted or bulky. I love the light color as it stands out on the road and can easily be seen by drivers. This jacket provided the right temperature when climbing and descending. It was perfect. The fit is truly race cut meaning it will feel most comfortable in riding position. I am considering ordering in black as well. Great piece to have in your collection!Show full review -

amazing
I was a little concerned over the 'race cut' description, but the jacket fit my girlfriend the same way other garments from Isadore do. She loves it and has worn it down to 28F with no complaints.Show full review
