ShadeMart 10ft x 17ft Rectangle Sun Shade Sail - Breathable UV Block

Our review of the ShadeMart 10' x 17' rectangle sun shade sail finds it best for homeowners and renters who need a heavy duty, breathable canopy for patios, carports or poolside equipment. The single biggest reason to buy is the combination of woven HDPE fabric and stainless steel corner D rings that deliver durable, UV-blocking shade while remaining water and air permeable, so it cools an area without trapping moisture. Installation is straightforward with basic hardware, and the sail offers an affordable, flexible alternative to permanent roofing.

Key Features

• Woven HDPE fabric: provides a durable, tear-resistant surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Stainless steel D rings: heavy duty corner hardware attached to white webbing for secure anchor points and long-term corrosion resistance.
• Water and air permeable: allows rain and air to pass through so the covered area stays cooler and avoids puddling or trapped moisture.
• Temperature reduction: lowers ambient temperature in the shaded area by roughly 10 to 15 degrees, improving comfort on hot days.
• Custom sizing available: a range of sizes can be ordered to fit specific venues, with guidance to measure accurately before purchase.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners, property managers, or DIYers who want an affordable way to create shaded space over a patio, carport, pergola, or pool equipment without building a permanent structure. It suits users who value ventilation and UV protection rather than full waterproofing.

Those who need a fully waterproof canopy or who require rigid structural roofing should look elsewhere; this style is explicitly not waterproof and is designed to be breathable. Also, buyers who cannot anchor to poles, walls, or trees without professional help should consider a different mounting solution.

Pros & Cons

Pros

• Durable woven HDPE material that resists tearing and blocks most UV radiation.
• Stainless steel D rings and reinforced white webbing offer strong, reliable anchor points.
• Breathable design reduces temperature and prevents water pooling during rain.
• Good value compared with permanent shade structures and easy to install with basic hardware.

Cons

• Not waterproof, so it will not keep an area completely dry during heavy rain.
• Manual measurement and cutting can introduce small size variations, so precise fitting requires careful measuring.
