ShadeMart 7 ft x 20 ft Green Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 7 ft x 20 ft Green Sun Shade Sail the bottom line is simple: it is a practical, heavy-duty shade solution for patios, carports and yards where UV protection and airflow matter most. The sail uses woven HDPE fabric with stainless steel D rings and heavy webbing, so the single biggest reason to buy is its combination of strong construction and effective sun blocking - it claims UPF50-level protection and cuts heat noticeably while remaining breathable.

Key Features

• Material: Woven HDPE fabric provides a durable, tear-resistant surface that stands up to sun exposure without becoming brittle quickly.
• UV Protection: Blocks up to 95% of harmful UV rays, providing significant sun protection for people and outdoor furniture beneath the sail.
• Breathability: The water permeable design lets water and air pass through, reducing pooling and keeping temperatures cooler under the canopy.
• Hardware: Stainless steel D rings attached to heavy white webbing create dependable anchor points for a secure installation.
• Custom Size Options: Available in a range of custom sizes so you can order dimensions that better match a patio, carport or pergola.
• Styling: The rectangle shape and green color make it an unobtrusive, decorative addition that integrates with many outdoor designs.

Who It's For

The ShadeMart rectangle shade sail is for homeowners and renters who need a robust, UV-blocking canopy for outdoor living areas like patios, pools, pergolas and carports, and who prefer a breathable, water permeable fabric instead of a waterproof tarp. It suits people who want a long-lasting fabric that reduces heat and resists sun damage.

Those who should look elsewhere include buyers who require a fully waterproof shelter or an exact precision-cut rectangle without any variation; customers who need rigid framing or integrated mounting hardware included may need a complete kit sold separately.

Pros & Cons

Pros
