Aero base layer

JARO Aero Base Layer

Aerodynamic sleeved base layer for warm-weather performance

Description

The JARO Aero Base Layer is designed for riders who don't compromise on speed and comfort, even under their jersey. This lightweight base layer combines excellent moisture management with an aerodynamically designed sleeve construction , making it perfect for summer rides, races, and intense training sessions .

The torso is made of a breathable pinhole fabric that quickly dissipates heat and keeps the body dry, even at high intensity. The sleeves are constructed of a striped stretch fabric that optimizes airflow around the upper arms when worn under a tight-fitting cycling jersey. The result is an efficient, streamlined transition between body and jersey—without additional heat buildup.

The Aero Base Layer is designed to perform invisibly: you'll barely feel it, yet it works with every step.
