More details
Fabric & Construction
The Sport-Tek ST350 uses 100% polyester interlock at 3.8 oz — a lightweight polyester interlock knit with a smooth, opaque surface on both sides. Interlock construction provides a cleaner print surface than single-knit jerseys. Set-in sleeve construction with crew neckline and tear-away label for custom rebranding.
Print Compatibility
Compatible with DTG, DTF, and screen print. The smooth polyester interlock surface accommodates all three methods. DTG on 100% polyester requires synthetic-compatible ink formulations. The PosiCharge technology is recorded as a color-lock attribute on the polyester fabric.
Buyer FAQ
Common questions
- What is PosiCharge technology on the ST350?
- PosiCharge is Sport-Tek color-lock technology recorded for this polyester fabric.
- What print methods work on the Sport-Tek ST350?
- DTG, DTF, and screen print. The smooth polyester interlock surface works with all three, though DTG on polyester requires synthetic-compatible inks.
- Does the ST350 have a removable label?
- Yes. The tear-away label can be removed for custom rebranding with relabeling or tagless heat transfers.
- How does polyester interlock differ from polyester jersey?
- Interlock is a double-knit construction that produces a smooth, opaque surface on both sides. Jersey is a single-knit that is thinner and has a distinct face and back side.
