Air Layer Heavy Fabric – 400 GSM Spacer Knit

Air Layer Heavy Fabric Specifications

Why Buyers Choose Air Layer Heavy Fabric

Outerwear and bags need fabric with real body. Air layer heavy fabric delivers a dense, padded hand-feel that gives jackets structure and bags shape, while the spacer construction keeps it lighter than its GSM suggests and warm without heavy lining.

For makers of bomber jackets, structured hoodies, backpacks and tote bags, this weight is a practical upgrade over lighter air layer: it hides filling lines, holds heavy prints, and wears well in cooler seasons.

We test weight tolerance, color fastness, shrinkage and wash performance before shipment, and keep stock shades in black, navy and grey for fast supply.

Applications

Best for structured hoodies and jackets, tote bags and backpacks and winter dresses that need a firm silhouette.

Customization

We can add water-repellent coating on this weight for outerwear and bags, adjust GSM and hand-feel, and support printing on select panels. Custom colors by lab dip in 3-5 days.

QC & Test

Batch testing covers color fastness (4+), shrinkage (≤3%), GSM tolerance and surface appearance after wash. Reports available on request.
