The FootJoy ThermoSeries Base Layer is designed for adaptable performance, allowing golfers to layer comfortably in all conditions. Featuring breathable 4-way stretch fabric, it wicks moisture away for lasting comfort while providing golf-specific compression to retain warmth without restriction. The raglan sleeve design enhances mobility, and reinforced lock-stitch seams ensure durability. An anti-microbial finish helps prevent odor buildup, making this base layer a reliable choice for year-round play.
