Product Overview
Tent Fly Fabric is a coated polyester Oxford fabric for rainflies and other weather-facing tent panels. It is used on expedition tents, base-camp shelters, rooftop tent rainflies, field shelters and outdoor covers that see rain, wind, humidity and repeated packing and pitching.

Key Advantages
Waterproofing with Moisture-Vapor Transfer
The fabric is 300D x 300D polyester Oxford with microporous PU on the inside and a C6 repellent finish on the outside. The Key Data Table gives water resistance of 8,000 mm H2O and breathability of 6,000 g/m2/24h. In practice, the coating system is intended to keep rain out while still allowing moisture vapor to pass through the fly during humid or multi-day use.
Tear and Wind Resistance for Exposed Panels
Tear strength is 90 N in warp and 80 N in weft, and the wind-resistance test records no damage at 1.0 kPa. These figures are relevant to a fly that is pulled tight over poles, hit by gusts or brushed by branches and wind-driven debris, because those conditions put concentrated loads into the fabric.
Seam and Fold Stability for Repeated Pitching
The table lists 25 mm seam tape, peel strength >=12 N/cm, seam water resistance of 6,000 mm H2O, and no coating cracks after 3,000 mechanical folds. That combination addresses two common weak points in frequently used shelters: taped seams and repeated fold lines.
Customization Capability
Coating System
The inner microporous PU and outer water-repellent finish can be adjusted to the approved performance brief, including the required coating feel and compatibility with the selected seam tape.
Color and Graphics
Solid colors, camouflage, identification graphics and project artwork can be matched from approved references for tent-fly production.
Functional Finishing
If the project calls for flame retardancy, a particular seam process or another functional finish, those requirements can be added to the final production specification.
Quality Control
- Before coating is released for final inspection, production checks cover the base construction, density, finished weight and coating build against the approved standard.
- Performance testing is tied to the Key Data Table and the order specification. Relevant items include water resistance, breathability, wind resistance, tear strength, UV aging, hydrolysis resistance, seam-tape peel strength, seam water resistance and repeated folding.
- Each finished roll receives a 100% visual check before packing for coating marks, pinholes, shade variation, edge defects, usable length and label accuracy. Independent third-party inspection can also be arranged when required.
FAQ
Q: How is the lead time confirmed?
A: Lead time is set once the fabric construction, coating, color and finishing requirements are fixed.
Q: What payment terms are used?
A: For regular products, the payment term is 30% deposit and 70% balance. Customized products use 50% deposit and 50% balance.
Q: Are water resistance and breathability measured as the same performance item?
A: No. Water resistance and breathability are different properties and are tested by different methods.
Q: Does the 1.0 kPa wind result certify the wind rating of a complete tent?
A: No. The 1.0 kPa result applies to the fabric test. The wind rating of a complete tent has to be validated on the finished structure.
