From high-output Nordic skiing to cold-weather cragging, our R1 Flash works as a do-everything technical pullover. Its high/low interior grid fabric stretches, breathes, moves moisture, and insulates - on the trail or off the ground. Sized for next-to-skin performance, it's still roomy enough to accommodate a thin base- layer. Low-grid polyester stretch panels under the arms and at the wrist and hem decrease bulk and increase breathability. To further reduce bulk, the elastic cuffs and the brushed-mesh chest pocket (now on the inside) are glued in. R1 Pants for men and women are available online at patagonia. com. Made in USA.
