Custom Size Rainbow Waterproof Sun Shade Sail 7ft x 20ft - UPF50

In this review the ColourTree 7' x 20' custom size rainbow sun shade sail is evaluated as a practical outdoor shelter for homeowners who need strong sun and rain protection. The bottom line: this shade sail is best for anyone wanting a heavy-duty, waterproof canopy that blocks UV while adding color to a patio or carport. Our review found the sail's 220 GSM pure virgin polyethylene fabric and commercial UV treatment deliver reliable shade and water resistance, while the reinforced stitching and 316 stainless steel D-rings make installation secure and long lasting.

Key Features

• 220 GSM pure fabric: The thick virgin polyethylene material provides durable coverage that feels substantial and resists tearing under normal outdoor tension.
• Waterproof coating: A waterproof layer prevents water penetration so the sail functions as both sun shade and light rain shelter for patios and carports.
• UV resistant finish: Commercial grade UV treatment enhances longevity and helps block up to 95% of harmful rays for cooler shaded areas.
• 316 stainless steel D-rings: Premium grade D-rings at each corner make attachment straightforward and resist rust in outdoor environments.
• Double reinforced stitching: All edges are finished with double-stitched seams to reduce fraying and distribute pull forces around mounting points.
• Three year limited warranty: The included warranty offers free replacement if you are not satisfied, providing added confidence in the purchase.

Who It's For

This shade sail is ideal for homeowners with a deck, pergola, carport, or play area who want a colorful, waterproof canopy that also blocks UV. It suits installations where a rectangular coverage area of approximately 7' by 20' is needed and where a sturdy, longer lasting fabric is preferred over lightweight mesh sails.

It is less appropriate for those who need custom framing hardware included, extremely large spans without intermediate anchor points, or a fully breathable fabric for constant airflow; in those cases a different style of canopy or professional shade structure may be a better fit.

Pros & Cons

Pros

• High quality 220 GSM virgin polyethylene feels robust and durable in normal outdoor use.
• Waterproof coating keeps water out, so furniture and ground beneath stay drier during light rain.
• 316 stainless steel D-rings and double-stitched seams improve longevity and installation strength.
• Attractive color options deliver a vibrant look while providing effective shade and UV block.

Cons

• May require intermediate anchor points or hardware sold separately for optimal tension over long spans.
• The heavier fabric is less breathable than mesh sails, so it can reduce airflow underneath.
