Custom Size 11ft x 20ft x 22.8ft Right Triangle Sun Shade Sail - Cool

Our review of this custom right triangle sun shade sail finds it best suited to homeowners and outdoor spaces that need a tailored cover with solid sun protection. The biggest reason to consider it is the combination of heavy 200 GSM HDPE construction and advertised 95% UV blockage, which translates into noticeably cooler shaded areas and a durable sail that stands up to sun and wind. Installation requires basic hardware and planning, but once mounted the sail delivers consistent shade, good color accuracy, and a neat, custom fit when measured D-ring to D-ring.

Key Features

• 95% UV Blockage: The fabric blocks most harmful rays to reduce sun exposure for people and furnishings beneath the sail.
• 200 GSM Construction: Heavy HDPE fabric gives the sail commercial-grade durability for long seasons of outdoor use.
• Temperature Reduction: Properly installed, the sail can lower ambient temperature by up to 15 degrees compared to unshaded spots.
• Custom Fit: The sail is made to order from D-ring to D-ring so it can match specific site measurements and edge preferences.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching increase longevity and resist fraying in wind and sun.
• Permeable Design: Water and air permeability reduce wind load and prevent pooling while still providing substantial shade.

Who It's For

This shade sail is ideal for homeowners, small hospitality spaces, and outdoor living areas that need a custom-sized right triangle canopy. People who prioritize strong sun protection, a cooler shaded spot, and fabric that stands up to frequent sun exposure will appreciate the heavy 200 GSM material and reinforced edges.

It is less well suited to buyers who want a ready-made off-the-shelf size or those who expect full waterproofing; the sail is water and air permeable by design. Also, customers who cannot or will not take precise D-ring to D-ring measurements should consider a different option to avoid fit issues.

Pros & Cons

Pros

• Durable 200 GSM HDPE fabric and reinforced stitching that hold up under sun and wind.
• Very effective shade with up to 95% UV blockage and a measurable temperature drop underneath.
• Customizable dimensions and straight-edge options allow a tailored look and fit for irregular spaces.
• Stainless steel D-rings provide reliable attachment points for mounting hardware.

Cons

• Some buyers report sizes feeling smaller than expected, so accurate D-ring to D-ring measurement is critical.
• Permeable fabric is not fully waterproof, so it will not create a dry sheltered area in heavy rain.

Our Verdict

For anyone who needs a sturdy, custom right triangle shade with strong sun protection, this sail is good value thanks to its 200 GSM fabric, reinforced hardware, and measurable cooling effect.
