ShadeMart 17ft x 24ft Blue Rectangle Sun Shade Sail - Breathable UV

In this review of the ShadeMart 17' x 24' Blue Sun Shade Sail, the bottom line is simple: this rectangle shade sail is best for homeowners and small businesses who want durable, breathable shade that noticeably cools outdoor areas without trapping water. The reviewer found the woven HDPE fabric and stainless steel corner D rings deliver solid build quality and straightforward installation, making it a practical choice for patios, carports, pergolas and poolside areas where sun reduction and airflow matter most.

Key Features

• Woven HDPE fabric: Provides a durable, tear-resistant surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Stainless steel corner D rings: Heavy duty D rings attached to reinforced white webbing offer sturdy anchor points for common hardware kits.
• Water and air permeable: The sail allows water to pass through so it does not pond, and the fabric promotes airflow to lower temperatures beneath the canopy.
• Temperature reduction: Customers report the shade lowers patio surface temperatures by around 10 to 15 degrees, improving outdoor comfort on hot days.
• Custom size options: A selection of custom sizes is available so buyers can match the sail to specific venue dimensions when measured accurately.
• Versatile installation: With proper hardware, the sail can be anchored to poles, trees, walls or roofs, adapting to many outdoor layouts.

Who It's For

This shade sail is ideal for homeowners with patios, small carports, pergolas or pool areas who want a cost-effective way to reduce sun exposure and heat while keeping airflow. It is a good fit for those who appreciate a decorative, rectangle canopy that integrates with existing landscape features.

Those who need a fully waterproof canopy or a rigid structure should look elsewhere, as this style is water permeable and designed to let rain pass through rather than create a dry sheltered area beneath. Buyers should also measure carefully if ordering a custom size, since dimensions may vary slightly due to manual production.

Pros & Cons

Pros

• Solid build quality with strong stitching and reinforced corner loops that hold up under tension.
• Effective shade and UV blocking that reduces surface temperatures and improves comfort.
• Easy to install using common hardware kits and attach points like poles or trees.
• Custom size options let you fit unusual spaces more precisely.

Cons

• Not waterproof, so it will not keep the area fully dry during rain.
• Some buyers report size or color variations, so careful measuring and expectations about shade tone are advised.
