Pearl Izumi Merino Wool Cycling Cap

The problem with so many cycling caps is that they are too bulky to fit under most helmets. Ours reduces that bulk by using the same 18.5-micron Merino/polyester plated construction found in our base layers, 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.
