ShadeMart 7 ft x 20 ft Blue Sun Shade Sail UPF50 - Breathable

Our review of the ShadeMart 7 ft x 20 ft Blue Sun Shade Sail finds it best for homeowners and renters who need a durable, breathable canopy to reduce heat and block UV without trapping moisture. The single biggest reason to buy is its combination of woven HDPE fabric and stainless steel corner D rings, which together provide reliable sun protection and long-term durability for patios, carports, and pool areas. It is especially useful where airflow and water permeability are needed rather than a fully waterproof cover.

Key Features

• Woven HDPE fabric: Provides a strong, tear-resistant shade surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Stainless steel D rings: Heavy-duty corner fittings attached to white webbing give secure anchor points for straightforward installation.
• Water permeable design: Allows rain and air to pass through so water does not pool on the sail and airflow is maintained under the canopy.
• Temperature reduction: Blocks sunlight and can lower the shaded area by roughly 10 to 15 degrees, improving outdoor comfort on hot days.
• Custom sizing available: A broad selection of sizes means you can order dimensions to match specific patios, pergolas, or carports when the standard sizes do not fit.
• Decorative rectangle shape: A clean, rectangular profile that integrates with many outdoor styles and is available in multiple colors.

Who It's For

This shade sail is well suited to homeowners, renters, and small property managers who need a cost-effective way to add shade over a patio, pool, or carport while preserving airflow and preventing water accumulation. It is a sensible choice where protection from UV and heat reduction are priorities but a waterproof canopy is not required.

People who should look elsewhere include those needing a fully waterproof shelter or an exact architectural rectangle for precision installations; some customers note minor variations from a perfect rectangle and this style is explicitly water permeable rather than waterproof.

Pros & Cons

Pros

• High UPF sun protection that noticeably lowers temperature under the sail.
• Durable construction with stainless steel D rings and heavy webbing for secure anchoring.
• Breathable, water permeable fabric prevents pooling and keeps airflow under the canopy.
• Custom size options make it adaptable to many outdoor spaces.

Cons

• Not waterproof, so it will not keep rain out of a covered area.
• Some buyers reported variations in shape or size from perfect rectangle due to manual measurements.
