Like a warm hug, this vest is built around Polartec(TM) Alpha(R) Direct insulation, wrapping you cozily all the way around while wicking moisture--even during intense efforts. The front panel features a wind-blocking, recycled stretch-woven fabric to shield you from the elements without compromising breathability. The Alpha Riding Vest is perfect for layering over a thermal jersey in cool conditions or wearing under a jacket for maximum warmth. The 2-way YKK zipper allows you to fine-tune ventilation while maintaining coverage where you need it. Staying true to our commitment to sustainability, the Alpha Riding Vest incorporates deadstock fabric and is made from recycled, bluesign-approved materials. Every vest is handmade in California with the same care and attention to detail as the rest of our collection.
