The cold-weather quarter zip is constructed in our favorite sweat wicking SoftSpeed™ fabric. Flattering design lines constructed with flatlock seaming prevents chafing on long runs. A hidden zipper pocket at the side seam is the perfect place to stash gels, keys and other goods, while thumbholes provide extra coverage. Other details include reflective branding hits at mock neck, center front, and center back. Perfect alone for when temps dip below 40 degrees and as a solid base layer when the temperature is below freezing. Inside bungee locker loop makes for easy storing and drying after a snowy long run.
