Stay Dry During Workouts – Thanks to HeatGear wicking fabric
HeatGear fabric is described as ultra-soft and smooth, engineered to be very lightweight while moving moisture away from the skin. The knit construction helps sweat reach the surface where it dries quickly.
Rapid moisture transport reduces dampness and chafing, helping youngsters feel comfortable during extended sessions.
Improved Ventilation – With strategic mesh panels
Strategic mesh panels are placed where extra ventilation is needed, increasing airflow across higher-heat zones. Mesh zones work alongside the knit fabric to accelerate drying.
Targeted airflow helps prevent overheating during intense drills and keeps temperature regulation more consistent.
Freedom of Movement – With 4-way stretch construction
4-way stretch construction allows the fabric to extend in multiple directions, accommodating a full range of motion without resistance. The stretch keeps seams and sleeves following movement rather than pulling against it.
Comfortable, unrestricted movement during warm-ups, training and match play, so young players can focus on performance.
