ShadeMart 13ft x 17ft White Sun Shade Sail UPF50 Rectangle - Cool

In this review of the ShadeMart 13' x 17' White Sun Shade Sail, the bottom line is straightforward: this rectangle UPF50 fabric sail is best for homeowners and small businesses who need breathable, reliable sun protection for patios, carports, or pool areas. The reviewer found the woven HDPE material and stainless steel D rings deliver a durable, weather-resistant canopy that noticeably reduces heat while allowing water and air to pass through, making it a practical option for long-term outdoor coverage.

Key Features

• Woven HDPE material: The high density polyethylene fabric blocks up to 95% of harmful UV rays while remaining breathable so it cuts sun exposure without trapping heat.
• Stainless steel corner D rings: Durable metal rings attached to heavy duty white webbing provide secure anchor points for easy installation.
• Water permeable design: The sail allows rain and air to pass through, so standing water is avoided and the covered space stays cooler and well ventilated.
• Custom sizing available: A range of sizes can be ordered to match specific venues, helpful when fitting irregular patios or carports.
• Rectangle styling: The simple rectangular shape integrates with many outdoor designs and works well when paired with basic mounting points like poles or walls.
• Multipurpose use: With proper hardware the sail can be mounted to trees, roofs, pergolas, or poles and applied to patios, pools, yards, and carports.

Who It's For

This shade sail suits homeowners, renters with outdoor space, and small commercial properties that want a cost-effective canopy to reduce sun and heat. It is especially valuable where airflow and drainage are important because the fabric is water permeable and breathable, and the UPF protection helps protect people and furniture.

Those who need a fully waterproof awning, a perfect geometric factory-cut rectangle every time, or who require integrated grommet-to-grommet snap systems should look elsewhere; this style is explicitly not waterproof and manual measurements may produce slight shape variation, so measure carefully before ordering a custom size.

Pros & Cons

Pros

• High UV protection: blocks up to 95% of harmful rays and lowers temperature under the sail.
• Durable components: woven HDPE fabric with stainless steel D rings and heavy webbing hold up in varied weather.
• Breathable and water permeable: prevents pooling and improves airflow under the shade.
• Custom size options: available to fit nonstandard spaces when measured accurately.

Cons

• Not waterproof: will not protect from heavy rain as it allows water to pass through.
• Size and shape variation: manual measurements can lead to sails that are not perfectly rectangular according to some buyers.

Frequently Asked Questions

Is this sail waterproof?
No. The fabric is water permeable and designed to allow water and air to pass through rather than be fully waterproof.

Will it reduce temperature under the sail?
Yes. The UPF50 fabric blocks a large portion of sunlight and customers report noticeable lowering of temperatures under the canopy.

Can I customize the size?
Yes. ShadeMart offers custom sizes but accurate measurements are required and manual measurement can cause slight variation in shape.
