Pearl Izumi Transfer Hat ($20, Pearlizumi.com)
Simplicity makes the Pearl Izumi Transfer Hat such a compelling piece. Because it is constructed of a lightweight yet thermal material, it kept the tester’s head adequately comfortable in cold conditions while preventing overheating on mild days. Fit was just right, and flat-lock stitching added to the fit and even allowed the tester to wear the Transfer hat under a helmet on the bike. The wicking capability of the fabric kept our tester’s head dry by moving moisture away from his head, further increasing the utility of the piece. Because of the thin material, the Transfer hat is also very packable, meaning you’ll likely reach for it to put in a jersey pocket just in case. Its ability to handle a wide range of temperatures and a variety of activities makes the Transfer hat our do-it-all choice in this review.
