In the high desert, fall means frosty mornings and afternoon temperatures that can go to the extreme in either direction. That’s when the tough and versatile Long-Sleeved R1® Field 1/4-Zip comes into its own. Made with lightweight, fast-wicking 6.3-oz 93% recycled polyester/7% spandex stretch fleece for comfort and insulation across a wide range of temperatures, the R1 Field moves with you and takes the chill out of the air. The shoulders, forearms and hem are reinforced with 96% nylon/4% spandex for enhanced durability and have a DWR (durable water repellent) finish to ward off light showers or dew-soaked vegetation. A single left-chest pocket is zippered for security, and when you’ve put enough miles behind you to heat up, the shirt compresses for easy packability.
