Sure, the sunny skies overhead tell you to run without a windbreaker. But weather can change from great to miserable in the blink of an eye, especially if you're near the mountains, so take The North Face Men's Feather Lite Storm Blocker Jacket with you. Fully taped seams work with the ripstop shell so you're ready for whatever mother nature throws your way. And the hood won't flap behind you because you can stow it away. When it stops raining, you can compress this jacket down and stuff it in your hydration pack. The adjustable hem prevents blustery winds from breezing up your body, and two PU zips protect your phone and keys from any stormy weather.
