Warm your ears and cool your brain. It's common knowledge that heat escapes from your head faster than anywhere else. When you're hammering away on the bike, it's OK to shed some heat, though. The Louis Garneau Ear Cover 2 is perfect for the days when the cold air might freeze your ears but a full cap would trap too much heat. The Ear Cover 2 is made of LG's Enerblock fabric, a stretchy polyester knit with a soft back and breathable membrane that keeps out wind and water. As a finishing touch, Garneau made the front logo reflective for an added hint of visibility, and added a hook-and-loop adjustment tab for a comfortable fit.
