Red Right Triangle Sun Shade Sail 17ft x 21ft x 27ft - Custom Fit

Our review of the Red Right Triangle Sun Shade Sail finds it best for homeowners and small businesses who need a durable, customizable shade solution that actually cuts sun and temperature. Built from heavy 200 GSM HDPE fabric, this canopy delivers the single biggest benefit buyers will notice: substantial sun protection and cooler shade, blocking up to 95% of UV while lowering ambient temperature by as much as 15 degrees compared with unshaded areas. For those seeking a tailored fit and long lasting performance, this sail is a solid option.

Key Features

• 95% UV Blockage: The fabric blocks up to 95% of harmful UV rays, protecting people and furnishings under the canopy.
• 200 GSM Commercial Material: Heavy HDPE construction provides strength and abrasion resistance for extended outdoor use.
• Temperature Reduction: The sail helps reduce ambient temperature by up to 15 degrees versus full sun, making patios and play areas more comfortable.
• Custom Size to Make: Measured from D-ring to D-ring, the right triangle can be made to fit specific spaces for a neat, tailored look.
• Durable Hardware and Stitching: Stainless steel D-rings, reinforced edges and double-layer stitching resist fraying and improve longevity.
• Water and Air Permeable: The breathable weave sheds some water and allows airflow, reducing wind load and pooling.

Who It's For

This shade sail is well suited to homeowners, cafes, and community spaces that need a permanent-looking shade canopy with a custom fit. People who value color accuracy and appearance will appreciate the way the fabric holds dye and looks once tensioned between mounting points.

It is not ideal for those who expect a waterproof awning or need instant pop-up shade; the fabric is water and air permeable rather than fully waterproof. Also, buyers who cannot measure D-ring to D-ring accurately or who prefer pre-cut standard kits without customization may want a different option.
