In our continuous quest to create more sustainable products, we've reengineered our customer-favorite RT7 Jacket for more earth-friendly performance. The shell and lining are 100% recycled polyester; the fill is a blend of recycled plastic bottles and crushed oyster shells that regulates temperature, wicks moisture, and breathes to keep you comfortable in all conditions. It's as at-home in the office as it is on a mountain hike.
