ShadeMart 11 ft x 17 ft Blue Sun Shade Sail UPF50 - Heavy Duty

In this review of the ShadeMart 11 ft x 17 ft Blue Sun Shade Sail, the bottom line is simple: this rectangle canopy is for anyone who needs durable, breathable UV protection for patios, carports, pools or pergolas. The biggest reason to buy is its combination of woven HDPE fabric and stainless steel corner D rings that deliver long-term sun blocking and robust attachment points without trapping heat. The fabric is water permeable, blocks up to 95% of harmful rays, and noticeably lowers surface temperatures, making it a practical choice for outdoor shade where airflow and UV defense matter.

Key Features

• Material: Woven HDPE fabric resists fading and provides long-lasting sun protection while remaining breathable so it does not trap heat.
• UV Protection: Rated UPF50 and able to block up to 95% of harmful UV rays, which helps lower temperatures in shaded areas.
• Hardware: Stainless steel corner D rings attached to heavy duty webbing offer secure anchor points and improved durability in wind and weather.
• Water Permeable: The sail allows water and air to pass through, so it drains rather than pooling and reduces stress on attachment points in rain.
• Custom Size Options: Available in a wide selection of sizes so users can order a sail matched to their space when accurate measurements are provided.
• Styling: Rectangle shape and color choices let the sail serve as both functional shade and a decorative outdoor element.

Who It's For

The ShadeMart 11 ft x 17 ft rectangle sail suits homeowners and renters who want effective UV protection for medium to large outdoor areas such as patios, carports, poolside spaces or pergolas. It is well suited for people who prefer a breathable, water permeable canopy that reduces heat rather than a solid waterproof cover.

Those who need a fully waterproof structure, a perfectly engineered geometric fit without any possibility of size variation, or who require rigid wind-rated canopies for commercial installations should look elsewhere. Also measure your site carefully before ordering a custom size to avoid fit issues.
