ShadeMart Turquoise 6ft x 21ft Rectangle Sun Shade Sail - UPF50 Canopy

In this review of the ShadeMart 6' x 21' Turquoise Sun Shade Sail, the bottom line is simple: it is a practical, heavy-duty solution for homeowners who want reliable sun protection and improved outdoor comfort. The reviewer found the sail's woven HDPE fabric and stainless steel corner D rings to be durable and weather-ready, and its UPF50 sun blocking and breathable, water-permeable construction make it especially useful for patios, carports, and poolside areas where ventilation and UV protection matter most.

Key Features

• Material: Woven HDPE fabric provides a durable, tear-resistant canopy that stands up to regular outdoor exposure.
• Sun protection: Blocks up to 95% of harmful UV rays with a UPF50-level barrier to noticeably lower surface and ambient temperatures.
• Breathability: Water permeable and breathable design allows rain and air to pass through so it does not trap heat or collect water.
• Hardware: Stainless steel corner D rings secured to heavy duty white webbing make attachment points sturdy for standard installation hardware.
• Custom sizing: Available in a broad range of custom sizes so the sail can be ordered to fit a specific patio, pergola, or carport footprint.
• Style: Rectangle shape and vibrant turquoise color add a decorative element while providing practical shade.

Who It's For

The ShadeMart rectangle sail is best for homeowners and renters who want a breathable, UV-resistant canopy for patios, carports, pergolas, pool decks, or yards and value easy-to-install, robust materials. It particularly suits people in sunny climates who need sun protection without a completely waterproof cover.

Those who need a fully waterproof canopy, a precisely cut architectural tension sail, or a rigid permanent structure should look elsewhere; this product is a water-permeable fabric sail intended for shading and airflow rather than total weatherproofing.

Pros & Cons

Pros

• High-quality woven HDPE fabric feels durable and resists tearing in typical outdoor conditions.
• Blocks up to 95% of UV rays and delivers a noticeable drop in heat under the sail.
• Water permeable design prevents pooling and allows air circulation for comfort.
• Stainless steel D rings and heavy webbing provide solid attachment points for mounting.

Cons

• Not waterproof, so it will not keep out heavy rain and is intended for shade rather than complete weather protection.
• Customers report size and shape can vary slightly due to manual measurement and fabrication, so careful measuring is required before ordering.
