ShadeMart 17ft x 17ft Green Sun Shade Sail UPF50 Square - Heavy Duty

Our review finds the ShadeMart 17' x 17' green sun shade sail is best for homeowners and small businesses who want a durable, breathable canopy that cuts solar heat and UV exposure without trapping water. In this review the standout benefit is its woven HDPE fabric and stainless steel corner D rings, which together deliver a rugged, weather-resistant shade solution that blocks up to 95% of harmful UV rays while remaining water permeable and breathable.

Key Features

• MATERIAL: The woven HDPE fabric provides a durable, tear-resistant surface that stands up to outdoor use and resists fading in sun-exposed settings.
• UV PROTECTION: Rated to block up to 95% of harmful UV rays, the sail significantly lowers surface and ambient temperatures in shaded areas.
• BREATHABLE DESIGN: Water permeable construction allows rain and air to pass through, preventing pooling and reducing wind strain on the cloth.
• HARDWARE: Stainless steel corner D rings attached to heavy duty white webbing provide reliable anchor points for common installation hardware.
• CUSTOM SIZING: Multiple size options are offered so customers can select or request dimensions to better fit patios, carports, pergolas or poolside areas.
• STYLING: The rectangle shape and color choice make it both a functional shade and a decorative addition to outdoor spaces.

Who It's For

The ShadeMart 17' x 17' sun shade sail is ideal for homeowners seeking to reduce heat and sun exposure over patios, carports, pool decks, or seating areas, and for small property owners who need a robust, low-maintenance canopy that breathes. Installers who prefer fabric that sheds water rather than holding it will appreciate the water permeable HDPE weave and reinforced corners.

Those who need a fully waterproof canopy, a perfect geometric rectangle without any size variance, or a rigid frame structure should look elsewhere; this product is a flexible fabric sail designed to be tensioned between anchors and may show small measurement variations due to manual sizing.

Our Verdict

Its sturdy HDPE weave, reinforced corners and good sun-blocking performance make it a reliable outdoor canopy for most residential uses, provided buyers measure carefully and accept that the fabric is not a replacement for solid roofing.
