This vest is built from a nylon Pro-Meteo 1 layer Airtastic™ fabric with a durable water repellent finish to keep you dry in light showers. It's super lightweight with a natural weft-stretch for windproof performance and the double ripstop construction means it's strong and durable. A backed lining with Polartec® Alpha® Direct insulation uses advanced adaptable breathability technology to regulate your body temperature in changeable conditions. With a zipped chest pocket, zipped back pocket plus elasticated double back pocket, you can easily store and access energy gels or other small items. The longer hem keeps your lower back covered as your tuck into a descent while non-slip silicone grippers on the hem hold the vest in place. Looking to shed layers mid-ride? No problem. The women's Rando Cycling Alpha Vest compresses down to fit in your pack easily.
