LeMieux Young Rider Mia Mesh Base Layer — UV50+ Quarter Zip for Active Young Riders

The LeMieux Young Rider Mia Mesh Base Layer is the perfect technical apparel for active young riders. Designed with UV50+ sun protection, this quarter zip base layer keeps young equestrians cool and comfortable during riding or outdoor activities.

Featuring ventilating mesh panels combined with sweat-wicking, thermal fabric, it provides optimal temperature regulation and breathability.

The silky-smooth material offers a stylish, tailored fit, while mesh inserts promote increased airflow for enhanced breathability.

Ultra-soft seams with flatlock stitching minimize chafing and pressure points, delivering a comfortable, pressure-free experience. The 360° stretch fabric ensures full freedom of movement, making it ideal as a base layer or stand-alone activewear for young riders.
