When you’re working out to the fullest, the Smartwool PhD Ultra Light Men’s 1/4 Zip Long Sleeve Top works equally hard to keep you cool and dry. Made from the lightest weight Merino wool and polyester blend from Smartwool, the shirt is airy and capable of quickly absorbing perspiration. Cool and comfortable mesh panels are positioned in the spots where guys like you sweat the most, and you can pull down the zip for added ventilation.
