Right Triangle 7 ft x 11 ft x 13 ft Sun Shade Sail - Heavy Duty UV

Our review of the Royal Shade right triangle sun shade sail finds it well suited for homeowners and light-commercial spaces that need reliable sun protection without blocking airflow. The single biggest reason to buy is the heavy-duty 200 GSM HDPE fabric that blocks up to 95% of harmful UV while remaining breathable, so the sail shades effectively yet resists pooling and wind load. Measurement details and reinforced corners make installation tidy and durable for patios, play areas, or pet runs.

Key Features

• Corner-to-corner measurement: Corners are measured from point to point so buyers get the expected footprint when planning coverage.
• Curved edge design: Slightly curved edges follow a calculated radian to keep the sail tight and prevent sagging in the middle for a neater appearance.
• 200 GSM HDPE fabric: Durable woven knitted material allows water and breeze to pass through while blocking up to 95% of harmful UV for long-lasting sun protection.
• Reinforced edges and stainless hardware: Double-layer stitched seams and extra stitching at corners protect against fraying and strengthen D ring attachment points for secure mounting.
• Breathable, low maintenance: The fabric resists fading and pooling, reducing maintenance and improving performance in typical outdoor exposure.

Who It's For

This sail is aimed at homeowners, small businesses, and property managers who need a robust triangular shade for patios, playgrounds, pet areas, or outdoor seating. It is particularly useful where airflow and reduced heat under the sail are priorities thanks to the breathable woven construction.

Customers who need perfectly straight edges for aesthetic reasons or who require an unusually shaped sail should consider a custom order or an alternate product, since the standard offering uses slightly curved edges to optimize tension and fit after installation.
