ShadeMart 17 ft x 20 ft Turquoise Rectangle Sun Shade Sail - UPF50

In this review the ShadeMart 17' x 20' Turquoise Sun Shade Sail is examined for homeowners and small business owners who need broad, breathable sun protection. The single biggest reason to buy is its effective sun blocking and cooling: the woven HDPE fabric is rated to block up to 95% of harmful UV rays and noticeably lowers temperatures beneath the canopy. The review focuses on installation practicality, material durability, and suitability for patios, carports, pergolas and garden areas where a water permeable, breathable screen is preferred.

Key Features

• Material: The woven HDPE fabric provides a durable, lightweight canopy that resists tearing and holds shape under tension.
• UV protection: The sail blocks up to 95% of harmful UV rays, helping to reduce temperatures beneath by roughly 10 to 15 degrees for more comfortable outdoor use.
• Corners and hardware: Stainless steel D rings attached to heavy duty white webbing give secure anchor points for common mounting kits and reduce stress at connection points.
• Breathability: The water permeable, air permeable design allows rain and wind to pass through, avoiding water pooling and improving airflow under the sail.
• Custom sizing: ShadeMart offers a range of custom sizes so you can order a fit matched to patios, carports or pool areas when exact dimensions are required.

Who It's For

The ShadeMart 17' x 20' sail is well suited to homeowners with medium to large patios, pergolas, carports or poolside areas who want a decorative yet functional shade solution that reduces heat and sun exposure. It also fits gardeners who need sun protection for plants or work areas where airflow and water permeability are important.

Those who should look elsewhere include buyers needing a fully waterproof canopy or an ultra-heavy commercial shade for permanent roofing; this style is designed to be water permeable and is not a waterproof solution. Also measure installation points carefully and consider professional rigging for complex multi-point installs.

Pros & Cons

Pros

• High UV blockage and measurable cooling under the sail provide reliable sun protection.
• Durable woven HDPE fabric and reinforced stainless steel D rings offer good longevity and strong anchor points.
• Breathable, water permeable design prevents pooling and improves comfort in varied weather.
• Custom size options let buyers match awkward or unique outdoor spaces.

Cons

• Not waterproof, so it will not keep an area dry during heavy rain.
• Color and perceived size can vary slightly due to manual measurements and fabric dye differences reported by some buyers.
