Quality Control and Assurance

Jon Monsir works with carefully selected partners who operate dedicated QA divisions to ensure ongoing quality assurance across all garments supplied. These partners maintain stringent quality control systems with every vendor involved in production and supply.

Sizing & Fit Consistency
Sizing accuracy is managed through regular inspections conducted by factory and vendor QCs. These checks begin at the cutting stage, continue through sewing lines, and extend to packing and finishing. Each garment is measured against an approved specification sheet covering both critical and non-critical points. Approved reference samples are maintained at production facilities for comparison, ensuring all bulk production aligns with agreed styling, construction, and measurement standards.

Colour & Fabric Standards
Before bulk fabric production, lab dips are reviewed and approved. Vendors must also provide shade bands for approval, establishing acceptable colour boundaries within each shipment. This process applies to every new order and repeat production run.

Fabric Performance & Durability
Fabrics are tested both qualitatively and quantitatively for finish and durability. Testing includes colour fastness across washing, crocking, dry cleaning solvents, light exposure, water resistance, and aging. Our partners collaborate with Intertek Testing Services (primary laboratory) and Qualspec Testing Centre (secondary laboratory) to validate fabric performance. Any materials that fail to meet standards are rejected, rectified by the manufacturer, and resubmitted for approval.

Laboratory machines for material testing: fatigue testing machine, instrumented impact tester, and a rotary viscometer.

Supply Chain Quality & Vendor Standards

Jon Monsir partners with a supply chain that has invested significantly in quality assurance infrastructure. This includes a dedicated QC laboratory located in Auckland, equipped with advanced testing machinery from James Heal UK. This facility enables continuous validation of fabric performance, including pilling, abrasion resistance, light fastness, and rubbing. Independent test reports are maintained and available for review upon request.

Our long-standing vendor network is committed to upholding stringent standards and delivering consistent quality. Their extensive local expertise and established networks within their regions of operation provide a strong advantage in ensuring compliance and reliability.
