PhD Light Reversible Beanie

The crew you run with every morning will never know you're running in the same Smartwool PhD Light Reversible Beanie day in and day out. For one thing, it's made out of naturally odor-resistant merino wool, so it won't smell like you did yesterday, and it's reversible so it looks like you own two. Clean finish seams and temperature-regulating fabric bring a heap load of comfort that won't keep you too warm or too cold while you run, ride, or work out in cold weather.
