Ultralight, highly breathable GORE-TEX shell for running in the mountains. The Norvan Jacket was previously the Norvan Shell Jacket.An ultralight solution for running in the rain, the Norvan Jacket offers exceptional breathability while keeping you dry. The fully waterproof fabric allows sweat to escape without letting outside moisture in so you can focus solely on the trail in front of you. Run-friendly details like vents under the arms make staying on pace no sweat. What's been updated: Updated with lighter, more durable, and PFAS-free 15D GORE-TEX ePE. Design updates include large reflective branding for low-light visibility, added ventilation, a new cuff construction paired with a wrist-watch window, a packable pocket, and features for easier adjustments on the trail. This product is free of intentionally added PFAS. The new ePE membrane technology is lighter and thinner, but just as strong and durable as the materials we used before.   You may notice the face fabric “wetting out” slightly faster in products with ePE membranes, but rest assured this does not affect the waterproofing of the membrane itself. If you notice the fabric wetting out faster than you’d like, simply wash the jacket and dry it to remove the oil contamination and bring the DWR back to its full power.
