Key Features Explained
The four-way stretch fabric is intended to move with the body, while the close compression fit differs from a loose-cut training shirt. The top is described for activities including running, cycling and gym training, and can be worn beneath a jersey or jacket or as a standalone shirt.
Although it has long sleeves, no temperature range or weather-protection rating is specified. Consider what you will wear over or under it for the conditions you expect.
