What a Good Bag Fabric Must Deliver
Bag fabric needs to hold its colour and shape through daily use. Our bag canvas is built around these six requirements.
Breathability
Natural cotton canvas lets air through, keeping contents fresh and preventing odours.
High water resistance
Dense weaves shed light rain, with water-repellent and wax finishes available.
Good light fastness
Vat and pigment dyes achieve grade 4 to 5 light fastness, so colours stay rich.
Wide colour range
Dyed to order in a broad, consistent palette for brand and seasonal collections.
Rot-proof & anti-bacterial
Anti-fungal tested canvas that resists mildew in storage and humid climates.
Flame & temperature resistance
Flame-retardant and heat-resistant finishes for industrial and tool bags.
