ShadeMart 20ft x 22ft Blue Rectangle Sun Shade Sail - UPF50 Protection

Our review of the ShadeMart 20ft x 22ft Blue Rectangle Sun Shade Sail finds it well suited for homeowners and RV owners who need broad, breathable sun protection without trapping heat. The biggest reason to consider this sail is its combination of woven HDPE fabric and stainless steel corner D rings that deliver durable, fade-resistant shade while remaining water permeable and breathable. Installation is straightforward with proper hardware, and the sail noticeably cuts glare and temperature in covered areas, making it a practical choice for patios, carports, and poolside use.

Key Features

• Material: woven HDPE fabric provides a durable, UV-resistant surface that blocks up to 95% of harmful rays while allowing air to pass through.
• Hardware: stainless steel corner D rings attached to heavy duty webbing give reliable anchor points that withstand regular tensioning.
• Breathability: the water permeable design keeps the area cooler and avoids pooled water after rain, reducing strain on the fabric and supports.
• Size options: available in custom sizes so buyers can match odd-shaped venues or larger outdoor areas when measured accurately.
• Versatility: rectangle styling and multiple colors allow the sail to be used across patios, pergolas, carports, and yards as both shade and a decorative piece.
• Temperature reduction: blocks sunlight effectively and lowers perceived temperature in the shaded area, improving comfort on hot days.

Who It's For

This sun shade sail is ideal for homeowners with a patio, poolside seating, carport, or RV area who want a durable, breathable cover that reduces UV exposure and heat without creating a sealed canopy. It works well for people who can either install hardware on existing structures or set posts to anchor the sail.

It is less suitable for buyers who need a fully waterproof canopy or those who expect perfectly consistent color or exact inch-for-inch sizing out of the box; the sail is water permeable and sizes are subject to small manual measurement variations, so customers who require rigid waterproofing or precise color matching should consider alternate solutions.
