Quality & Fabric Standards
We hold our tribute apparel to strict production and textile integrity standards:
-
Hypoallergenic Performance Mesh: 100% skin-friendly recycled polyester fabric free of harsh irritants or chemical residues.
-
Reinforced Stress Points: Dual-needle seam construction at the shoulders, collar, and hem resists fraying even during high-impact movement.
-
Rigorous Quality Inspection: Every single piece is individually inspected for embroidery precision and tag accuracy before dispatch.
Care & Wash Instructions
Follow these simple recommendations to protect the embroidery and fabric for seasons to come:
-
Turn Inside Out: Always turn the jersey inside out before washing to safeguard stitched names and twill numbering.
-
Cold Water Wash: Machine wash cold (30°C / 86°F or below) on a gentle cycle with similar colors using mild detergent.
-
Hang Dry Only: Air dry on a hanger out of direct sunlight. Do not tumble dry to prevent synthetic shrinkage and protect embroidery stiffness.
-
No Direct Ironing: If needed, use a light steamer or place a damp cotton cloth between the iron and the jersey on low heat. Never apply heat directly to numbers or crests.
