Custom Size 25 ft x 25 ft Black Triangle Sun Shade Sail - UPF50

Our review of this custom size black triangle sun shade sail finds it best suited for homeowners or small businesses that need heavy-duty UV protection tailored to an exact space. The single biggest reason to buy is the combination of commercial-grade 200 GSM HDPE fabric and a customizable D-ring to D-ring measurement method that delivers reliable 95% UV blockage and a cooler shaded area. Installation takes some planning, but the reinforced edges and stainless steel D-rings make this a durable, long-term canopy option rather than a seasonal stopgap.

Key Features

• 200 GSM fabric: Heavy-duty HDPE material offers a sturdy, long-lasting canopy suitable for frequent outdoor exposure.
• 95% sun protection: The sail blocks up to 95% of harmful UV rays, helping protect skin and outdoor furnishings.
• Temperature reduction: Properly installed, the sail can lower ambient temperatures by up to 15 degrees compared with unshaded areas.
• Custom sizing: The product is ordered to make with D-ring to D-ring measurements so the sail can be tailored to irregular or exact spaces.
• Reinforced hardware: Stainless steel D-rings and double-layer stitching reduce fraying and increase longevity, with a 3 year assurance.
• Breathable and water permeable: The weave remains air and water permeable so it vents heat rather than trapping it underneath.

Who It's For

This shade sail is ideal for homeowners, cafes, playgrounds, and patios that need a robust, custom-fit canopy to cut UV exposure and lower surface temperatures. People who value durability and want a tailored edge-to-edge fit will appreciate the D-ring measurement approach and reinforced construction.

Those who should look elsewhere include buyers needing an off-the-shelf, immediately ready size without custom ordering or customers who want a fully waterproof solid canopy; this product is permeable and requires thought about anchor placement and corner gap allowances before installation.
