Pearl Izumi Transfer Wool Cycling Cap

The problem with so many cycling caps is that they are too bulky to fit under most helmets. The Pearl Izumi Transfer Wool Cycling Cap reduces that bulk by using a 18.5-micron Merino/polyester plated construction, so that it will fit under a helmet and wick moisture away as it regulates temperature. A flexible, durable insert in the bill ensures it will survive machine washing.
