Merino Wool Cycling Cap for Men & Women - Breathable & Moisture-Wicking Bike Hat for Road & Mountain Biking - Perfect for Outdoor Sports & Commuting

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.
