ShadeMart 17ft x 17ft Turquoise Sun Shade Sail UPF50 Square

In this review of the ShadeMart 17' x 17' Turquoise Sun Shade Sail, the bottom line is simple: this heavy-duty woven HDPE canopy is for homeowners or small businesses who want durable, breathable UV protection rather than a waterproof cover. The reviewer found the sail very effective at lowering surface temperatures and cutting direct sunlight, making it a practical choice for patios, carports, and poolside shade. It is best chosen when breathability, UV block and long-term durability are priorities rather than complete rain protection.

Key Features

• Material: Woven HDPE fabric resists tearing and stays stable outdoors, providing a durable long-term shade surface.
• UV Protection: Blocks up to 95% of harmful UV rays and sunlight, helping to reduce temperatures by roughly 10 to 15 degrees under the canopy.
• Breathability: The water permeable, breathable design allows air and rain to pass through rather than pooling, which reduces wind load and ponding risks.
• Hardware Ready: Stainless steel corner D rings attached to heavy duty white webbing make it simple to pair with standard mounting kits and anchor to poles, walls or trees.
• Custom Sizing: A range of custom sizes is available so customers can match irregular or large venues, with the fabric area maintained even if manual measurements vary.
• Style: Rectangle shape and bright turquoise color add a decorative element that integrates with patios, pergolas and carports.

Who It's For

The ShadeMart 17' x 17' sail is ideal for homeowners, small venue owners and landscapers who need strong sun protection and airflow for outdoor living spaces such as patios, pools and carports. It is especially useful where heat reduction and UV blocking are the top priorities and where a breathable membrane is preferred to a solid waterproof roof.

Customers who need a fully waterproof cover, or who require perfectly precise factory-cut geometry for exact architectural installs, should look elsewhere; the product can vary slightly due to manual measurement and is explicitly water permeable rather than waterproof.

Pros & Cons

Pros

• Durable woven HDPE construction and stainless steel D rings deliver long-lasting strength and reliable mounting.
• High UPF performance reduces heat and sun damage to outdoor furniture and skin.
• Breathable design prevents water pooling and improves airflow beneath the canopy.
• Custom size options make it adaptable to many installation layouts.

Cons

• Not waterproof, so it will not keep the covered area dry during heavy rain.
• Some customers report size or shape variation from manual measurements, so careful measuring is required.
