When it's a bit cool and windy, a warm core can make all the difference in limiting the amount of energy your body loses to the weather. An obvious solution: a good vest, which will keep the wind at bay without overheating you or constricting your natural running movement. An added bonus to a wind vest is that it will pack even more snugly than a comparable jacket, so there's no excuse for leaving it behind if the weather at the trailhead is the least bit iffy.

Salomon's Fast Vest is constructed of a combination of ClimaWind Teflon and ClimaWind Stretch fabrics to put maximum wind protection where it's most needed without sacrificing a bit of comfort or flexibility. Also features reflective details and attractive, functional elastic cuffs at the waist, shoulders, and neck. Perfect for summer at high altitudes and shoulder seasons everywhere.
