The PEARL iZUMi Thrm Cyc Cap is designed to keep you riding comfortably when the temperature drops. Built as a thermal cycling cap, it fits neatly under your helmet to add a crucial layer of insulation without bulk. Soft, brushed fabrics typically used in this style of cap help trap warmth while still allowing your head to breathe, so you stay cozy rather than clammy on long, cold rides. A close, low-profile fit helps it work with most modern helmets, making it a versatile choice for road, gravel, or commuting.
This type of thermal cap usually features an extended ear and forehead panel to shield sensitive areas from windchill, helping you maintain focus and comfort in harsh conditions. Moisture-wicking materials draw sweat away from your skin, reducing the risk of getting chilled as you work harder on climbs or intervals. Lightweight and easy to pack in a jersey pocket or bag, the PEARL iZUMi Thrm Cyc Cap is an essential accessory for building a reliable winter or shoulder-season riding kit.
