Patagonia Slope Runner Vest The Patagonia Slope Runner Vest is designed to carry all your essentials when running trails on a big day out. It makes space for hydration, nutrition and the extra layers you may need when running from dawn to dusk and even beyond. The front is made from soft and flexible polyester, ensuring lightweight comfort, while the durable water-repellent (DWR) finish adds some extra protection in damp, drizzly conditions. To the back the hydrophobic mono-mesh panel regulates body temperature, allowing for airflow and breathability for all-day freshness.  Water-bottle-friendly stretch pockets keep your hydration easily accessible, with two 500ml HydraPak® flasks included to slip into the pockets perfectly. Trekking poles are easily stowed via two sets of elastic loops, one to the front of the pack for easy access, and the other tucked away to the back.
