SUNNY GUARD Shade Cloth Custom Size 3x21 ft - 95% UV Block

Our review of the SUNNY GUARD Shade Cloth finds it best suited to homeowners and gardeners who want a heavy-duty, customizable sun screen that balances strong sun protection with airflow. The cloth blocks about 95% of sunlight while remaining breathable, so it creates a shaded, private area without turning a patio into a cave. Installation is straightforward thanks to reinforced edges and copper grommets placed roughly every 2 ft, and the HDPE knit fabric feels robust for regular outdoor use.

Key Features

• 95% Sun Protection: Blocks the majority of direct sunlight to reduce heat and UV exposure while still allowing usable light beneath the canopy.
• Breathable HDPE Fabric: The knit construction permits air flow so shaded areas remain ventilated and comfortable on warm days.
• Double Reinforced Edges: Reinforced hems resist tearing and abrasion, extending the life of the shade when tied down or used in wind.
• Reinforced Copper Grommets: Heavy-duty, rust-resistant grommets every 2 ft make hanging and securing the cover simple and reliable over time.
• Custom Size Option: Available in the custom 3x21 ft size reviewed here, suitable for long pergolas or narrow runways of shade.
• Versatile Outdoor Use: Designed for pergolas, patios, pools, carports and gardens, giving seasonal protection for people and plants.

Who It's For

This shade cloth is a practical choice for homeowners with pergolas, long porches or narrow backyard runs who need a durable, customizable cover that blocks most sun while maintaining airflow. It's also a good pick for gardeners and small-scale growers who want to protect plants from harsh midday sun without blocking ventilation.

Those who should look elsewhere include buyers who want a fully opaque blackout tarp or an impermeable waterproof cover, since this HDPE fabric prioritizes breathability over complete water resistance. Also consider alternatives if you need a precisely measured factory-cut commercial shade with different percentages of light blockage.
