Here we have all three of Adidas training t-shirts/Soccer shirts for comparison.
Climalite = fabric that wicks and transports liquid sweat away from the body when you train.
Climacool = combination of performance fabrics, open mesh and ventilation to keep your body cool when you train.
Clima 365 = for all year round, from cold to warm, but when it is VERY hot, it will not cool you down that much.
