Product notes

More details

Fabric & Construction

The Sport-Tek LST350 uses the same 3.8 oz 100% polyester interlock with PosiCharge color-lock technology as the unisex ST350. The differentiator is the slim fit — a contoured cut for women's proportions rather than the regular unisex fit. Crew neckline with set-in sleeve construction and tear-away label.

Print Compatibility

Compatible with DTG, DTF, and screen print. The slim fit may require adjusted print sizing compared to the unisex ST350 — the narrower torso width affects chest print dimensions.
