Nike Men's PrimaLoft Trail Running Vest

Tough trails don't wait for clear skies. The Nike Therma-FIT PrimaLoft Trail Vest wraps your core in a protective layer so you can keep pushing when the elements turn against you. It's built for runners who refuse to let the forecast dictate their training. Throw it on for early morning hill sessions, exposed ridges, or those blustery winter runs.

Product Highlights:
• Stay warm without the bulk with PrimaLoft synthetic insulation that traps body heat efficiently
• Regulate your temperature with Therma-FIT technology built to perform in shifting conditions
• Keep your arm swing free on technical descents with a sleeveless cut that stays out of your way
