Gildan G448 - Unisex Performance® Jersey Polo - Marble Navy

The Gildan G448 Performance Jersey Polo is a 4.7 oz 100% filament polyester sport shirt built for corporate programs, team uniforms, and promotional runs where moisture management and professional appearance both matter. The filament polyester yarn is spun in longer continuous strands that create a tighter jersey knit than staple-spun poly, which gives the G448 its snag resistance and a smoother print surface than textured pique polos. It wicks moisture, carries antimicrobial properties to control odor between washes, and provides UPF 30+ sun protection on all non-white colours. The contoured welt collar, three-button placket with smoke grey pearlized buttons and reinforced bottom box, rolled-forward topstitched shoulder seams, and side vents keep the shirt looking pressed without ironing.

For sublimation, the G448 is one of a small number of wholesale polos that sublimate cleanly because it is 100% polyester with a smooth jersey face. Solid white gives the widest colour gamut, but the marble colourways (heathered poly blends) accept sublimation with a muted, vintage tone that works for retail-branded merch. Press at standard sublimation time and temp. For embroidery, the 4.7 oz jersey is light enough to need stabiliser behind the hoop on left-chest and full-front placements, but the filament poly resists needle-cut fraying better than staple-spun fabrics, so registration stays clean on detailed crests and multi-colour logos. For DTF, the polyester surface bonds well with transfer adhesive at standard heat and pressure. Screen printing works on this fabric with plastisol or water-based ink, though 100% polyester requires a low-bleed or poly-block underbase on coloured grounds to prevent dye migration at cure temps. Vinyl/HTV adheres cleanly at moderate temperature.

The marble colourways on the G448 are a cross-dyed heathered effect in the polyester yarn itself, not a garment wash. That means shade consistency is locked at the knitting stage and holds between production lots with less variation than pigment-dyed garments. For sublimation on marble grounds, expect the heather base to shift your transferred colours slightly toward muted tones compared to solid white, so proof on the actual colourway before committing a full run.
