Product Details
Castelli Medio Short Sleeve Base Layer
Enhance your cool-weather rides with the Castelli Medio Short Sleeve Base Layer, the ideal mid-weight option for transitional conditions where layering is key. Designed for medium insulation and maximum moisture management, this essential base layer keeps you warm without overheating, while efficiently wicking sweat away to maintain a dry, comfortable ride. Made from soft, 100% polyester stretch fabric, it offers a close-to-body fit that layers smoothly under short or long-sleeve jerseys alike.
With its short-sleeved design and crew-neck collar, the Castelli Medio is perfect for pairing with arm warmers or wearing under windproof layers, offering flexibility as conditions change. The excellent moisture control prevents chills after climbs or intervals, while the moderate insulation keeps your core warmer on fresh mornings or breezy descents.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
