Fabric & Construction
The Sport-Tek ST550 uses 3.8 oz 100% polyester interlock with PosiCharge color-lock technology in a polo silhouette. This is the unisex interlock polo in the Competitor line — using the same fabric as the ST350 tee and ST104/LST104 polos. Set-in sleeve construction with tear-away label. The interlock construction distinguishes it from the tricot-based ST650 Micropique polo.
print methods
Compatible with embroidery and screen print. The polyester interlock surface with PosiCharge color-lock provides a stable base for both methods. Left-chest embroidery is standard for polo decoration.
