Description
The Gildan G424B is a 4.5 oz 100% polyester jersey knit youth performance long-sleeve tee built for high-volume decoration programs where moisture management and a consistent print substrate matter. The no-snag polyester construction and heat transfer CPSIA tracking label make it a clean, ready-to-decorate blank for school athletic programs, youth sports leagues, spirit week runs, and event merchandise. AquaFX wicking keeps the fabric comfortable during activity, and Freshcare anti-microbial treatment reduces odour retention through repeated wash cycles. With 10 colours available including High Viz Safety Green (ANSI/ISEA 107 compliant), the G424B covers the spectrum from team basics to visibility-mandated youth workwear applications.
At 100% polyester, the G424B leads with sublimation as the primary decoration method. Full-body or all-over sublimation produces photographic-quality, wash-stable colour that does not crack, peel, or fade because the dye bonds directly to the polyester fibre. For sublimation, use white or light-coloured G424B blanks only since the process requires a white base to achieve accurate colour reproduction. DTF heat transfers bond well to the polyester surface across all colours including darker shades, making DTF the preferred route for smaller runs and multi-colour chest prints on any colourway. For screen printing on white and light G424B shirts, standard plastisol inks work cleanly on the smooth polyester face. On coloured G424B shirts, the 100% polyester construction creates significant dye migration risk under heat. Use a high-opacity low-bleed or poly-blocking plastisol underbase and cure at the minimum effective temperature to prevent ink discolouration. Vinyl and HTV apply reliably on the flat polyester surface with standard time and temperature settings. DTG is not recommended as the polyester fibre does not accept pretreatment chemistry effectively and results in poor ink adhesion and coverage. For ANSI-compliant High Viz Safety Green, route to DTF or sublimation for the clearest, safest result; screen printing risks dulling the fluorescent dye.

Decoration Method Compatibility
How this blank performs across popular decoration methods.
| Method | Compatible | Notes |
|---|---|---|
| Sublimation | ✓ | 100% polyester = full sublimation on white and light blanks; dye bonds directly to fibre for photographic wash-stable colour; not viable on dark or coloured blanks |
| DTF Transfer | ✓ | Works across all colours including dark grounds; preferred for smaller runs and multi-colour chest prints where sublimation is not available; bonds reliably to polyester |
| Screen Print (Plastisol) | ✓ | Works cleanly on white and lights; coloured G424B shirts need a high-opacity low-bleed poly-block underbase at minimum cure temp to prevent dye migration from the 100% polyester |
| Vinyl / HTV | ✓ | Reliable on the flat polyester surface at standard time and temp; use quality HTV rated for polyester to prevent peeling |
| DTG | ✗ | 100% polyester does not accept pretreatment chemistry; ink adhesion is poor; route to DTF or sublimation |
| Screen Print (Water-based / Discharge) | ✗ | Discharge chemistry requires cotton fibre to activate; no effect on 100% polyester; use plastisol with poly-block |
| Embroidery | ✗ | Lightweight 4.5 oz polyester jersey puckers under the hoop; not recommended for left-chest or back placements |

Fabric Blend by Color Group
Not all colorways share the same fabric composition. Check the blend before ordering for decoration jobs where substrate matters.
| Color Group | Blend | Print Consideration |
|---|---|---|
| White | 100% polyester | Full sublimation possible; best surface for all-over or photographic prints; standard plastisol screen print with no migration risk |
| Light solids (Carolina Blue, Royal, Orange, Red, Navy) | 100% polyester | DTF preferred for multi-colour chest art; sublimation not viable on pre-dyed colours; screen print needs poly-blocking underbase at minimum cure temp |
| Dark solids (Black, Charcoal, Sport Gray) | 100% polyester | DTF is the most practical route; screen print requires high-opacity poly-block underbase; sublimation will not show on dark grounds |
| High Viz Safety Green | 100% polyester, ANSI/ISEA 107 | DTF or sublimation recommended to preserve fluorescent visibility; avoid screen printing which risks dulling the safety dye under heat |
