9 ft x 12 ft x 15 ft Red Right Triangle Sun Shade Sail - Custom Fit

Our review of this custom-size red right triangle shade sail finds it best for homeowners and businesses who need a tailored, high-coverage sun shelter. The single biggest reason to buy is the fabric performance: made from 200 GSM HDPE it offers 95% sun protection while remaining breathable, so it cuts heat by up to 15 degrees without trapping moisture. Installation is straightforward for anyone comfortable with basic mounting hardware, and the option to order by precise D-ring measurements means the sail can be made to fit an odd-shaped patio or commercial seating area.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, protecting people and surfaces below.
• Temperature reduction: The weave and color reduce temperatures by as much as 15 degrees compared with unshaded areas for a cooler outdoor space.
• Custom sizing: The sail is made to order from D-ring to D-ring so customers get a tailored fit for irregular or planned layouts.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching improve longevity and resist fraying.
• Breathable and water permeable: The material allows air and water to pass through, reducing wind load and pooling during light rain.
• Easy installation: Can be attached to trees, rooflines, walls or poles using standard mounting hardware and following corner gap guidance.

Who It's For

This shade sail suits homeowners with patios, pergolas or play areas who want a customized fit and strong UV protection, and small businesses seeking a commercial-grade canopy that looks good and cools the seating area. It is also a sensible choice for DIY installers who can measure precisely from D-ring to D-ring and follow simple mounting rules.

Those who want a fully waterproof awning or a permanent rigid structure should look elsewhere, since this product is a breathable, water-permeable fabric sail intended as a sunshade rather than a rainproof canopy. If you need a ready-made size without custom ordering, a stock sail may be quicker.
