Cycling Baselayers

PEARL iZUMi cycling baselayers are designed to regulate temperature, manage moisture, and enhance comfort no matter the season. Worn under a jersey or jacket, these performance-first layers act as the foundation of your kit—keeping you cool in the heat, warm in the cold, and dry when the effort ramps up. Whether you’re racing, training, or riding for fun, a great baselayer makes every ride better.

From ultralight mesh for summer epics to thermal knits for winter base miles, our cycling baselayers offer seamless stretch, next-to-skin softness, and body-mapped ventilation zones. Many styles are made with recycled or sustainable fabrics to reduce environmental impact without sacrificing performance.

Ride-Ready Versatility for Road, Gravel, and Trail

Layer beneath your favorite cycling jersey or cycling jacket to build a system that works as hard as you do. Our baselayers are engineered for road rides, gravel grinds, and even off-season indoor sessions—helping you stay comfortable and dialed, mile after mile.

Complete your foundation with cycling bibs and shorts featuring our Levitate™ chamois, and add performance accessories like gloves, socks, and cycling shoes to round out your ride kit. With the right baselayer, you can adapt to the elements and stay in control—no matter where the ride leads.
