Right Triangle Sun Shade Sail 11ft x 17ft x 20.2ft - UPF50

Our review of this right triangle sun shade sail finds it best for homeowners and small businesses who need broad, flexible sun protection without a permanent structure. The biggest reason to consider it is its combination of heavy-duty 200 GSM HDPE fabric and 95% UV blockage, which delivers substantially cooler shaded areas and reliable sun defense for patios, play areas, and outdoor dining. Installation is straightforward for anyone comfortable with basic hardware and rigging, and the customizable D-ring measurements make it a practical choice when a tailored fit matters.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays for safer use of outdoor spaces during peak sun.
• Temperature reduction: The sail lowers ambient temperatures by up to about 15 degrees compared to unshaded areas to make patios and decks more comfortable.
• Custom sizing: Measurements are taken D-ring to D-ring so the sail can be made to fit the intended attachment points precisely.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity under regular outdoor use.
• Permeable material: The fabric is water and air permeable, which helps reduce wind load and prevents water pooling while still providing shade.
• Versatile installation: It installs to trees, walls, poles or roofs using standard mounting hardware, giving many placement options.

Who It's For

This shade sail is ideal for homeowners with a defined triangular area to cover, small businesses adding shade to a seating area, and anyone who wants significant sun blockage without a rigid canopy. It suits people who can measure D-ring to D-ring and either install themselves or hire a handyman for secure anchor points.

People who need a permanent, enclosed shelter or who require guaranteed multi-year marine-grade warranties should look elsewhere; while the sail has reinforced stitching and a 3 year assurance, long-term lifespan in extreme UV exposure received mixed feedback from some users.
