17ft x 19ft x 25.5ft Red Right Triangle Sun Shade Sail - Custom Fit

Our review of this custom right triangle shade sail finds it best suited for homeowners and small commercial patios who need a tailored, heavy-duty canopy that cuts sun and heat. The single biggest reason to buy is its combination of commercial-grade 200 GSM HDPE fabric and measured-to-fit construction, which delivers strong UV protection and a neat, custom installation that holds up to sun and wind without feeling flimsy.

Key Features

• 95% UV Blockage: The fabric blocks up to 95% of harmful UV rays, so shaded areas stay safer for skin and furnishings.
• 200 GSM Durability: Made from heavy 200 GSM HDPE, the sail resists fraying and handles seasonal sun and wind better than lighter options.
• Temperature Reduction: The canopy can lower ambient temperatures by up to 15 degrees versus unshaded areas, making outdoor spaces noticeably cooler.
• Custom Fit: Measured D-ring to D-ring sizing lets installers get a precise fit for odd corners and angled patios.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching improve longevity and reduce the chance of edge failure.
• Air and Water Permeable: The weave allows airflow and some water passage, reducing wind load and pooling.

Who It's For

This shade sail is ideal for homeowners, restaurants with outdoor seating, and backyard gardeners who need a large, angled canopy that can be custom measured to fit a specific triangular layout. It works well where a fixed pergola is impractical and where long-term sun protection is desired.

It is less suitable for buyers who want a fully waterproof awning or a lightweight seasonal cover; because the fabric is breathable and water permeable, it will not keep out heavy rain the way a coated waterproof tarp would. Also, buyers who need an off-the-shelf square or circular shade may prefer a standard size rather than a custom right triangle.
