This is the Teton Bros Run with Octa. Color: Brown (looks more like beige) Size: S Purchased 6 years ago. This insulation wear is perfect for intense activities in cold regions. Octa, a high-tech brushed material, is placed strategically, avoiding areas prone to overheating like the back and underarms. It also features diagonal double zippers that function as ventilation, making it exceptionally easy to regulate body temperature. Although this product is designed for running in the fall and winter, I tend to overheat easily, so I've only worn it a couple of times.
