The SmartWool PhD Seamless Strappy lets you skip the sweat and chill routine with a Merino next to skin feel that transitions easily from workout to caf+ 1/4 and doesn't leave you shivering. A Merino covered elastic band at the ribcage provides a secure anchor point for seamless Merino knit cups, which help regulate temperature and moisture. Adjustable straps get you to that perfect fit.
