Nonlaminated R1 (made with recycled polyester content) side panels and collar enhance next-to-skin comfort and breathability, seam-free shoulders improve pack-wearing comfort, and the hand pockets ride high, above the harness-line. With a zippered interior chest pocket. Recyclable through the Common Threads Recycling Program.
