Don't get caught between seasons - or weather systems - without a thing to wear. Instead, zip on the Impact Half Zip from New Balance. Its poly/Spandex fabric and mesh panel provide just the right amount of protection and breathability while NB DRY moisture wicking technology helps keep sweat from ruining your run. A secure zip pocket lets you stash your music, thumbholes and a draft flap up your comfort level, while reflective details help you be seen when the sky turns dark.
