What is the difference between an endurance jersey and a race jersey?

An endurance jersey has a slightly more generous fit across the chest and shoulders, a longer torso, deeper pockets, and often a fourth zippered pocket. A race jersey is skin-tight for maximum aerodynamics with shallower pockets and lighter fabric. Endurance jerseys prioritize comfort over 4+ hours; race jerseys prioritize minimal drag for competition. If you do not race, the endurance jersey is almost always the better choice.
