ShadeMart 20ft x 22ft White Sun Shade Sail UPF50 Rectangle

In this review the ShadeMart 20ft x 22ft White Sun Shade Sail is evaluated for homeowners and outdoor entertainers who need a large, breathable canopy that blocks harsh sun. The bottom line: it is best for people wanting durable, UV-resistant shade rather than a waterproof cover. The sail's woven HDPE fabric and stainless steel D rings make installation secure and long lasting, and its UPF50 rating delivers meaningful sun protection while allowing air and water to pass through, keeping patios and carports noticeably cooler and well ventilated.

Key Features

• Woven HDPE fabric: The high density polyethylene construction gives the sail strength and tear resistance while remaining lightweight for easier handling.
• Stainless steel D rings: Heavy duty stainless steel corner rings attached to reinforced white webbing provide secure anchor points and resist corrosion outdoors.
• Water and air permeable: The fabric lets water and breeze pass through, reducing wind stress and preventing pooling during rain.
• UPF50 sun protection: Blocks up to 95% of harmful UV rays to reduce direct sun exposure and lower surface temperatures under the canopy.
• Custom size options: Available in multiple measurements so users can match irregular patios, carports, or pool areas when measured accurately.
• Rectangle styling: A clean rectangular shape that integrates with many outdoor designs and can be mounted to trees, poles, walls, or roofs with proper hardware.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners, renters with outdoor decks, carport and pergola owners, and small business outdoor seating areas that need reliable sun protection and airflow. People who prioritize UV blocking, breathability, and a heavy duty attachment system will find the sail especially useful.

It is not the right choice for customers seeking a fully waterproof canopy or for installations where complete rain protection is required. Those needing a solid, sealed cover should consider a waterproof awning or hard-top solution instead.

Pros & Cons

Pros

• Durable woven HDPE material provides strong, long lasting shade without heavy weight.
• Stainless steel D rings and reinforced webbing make for robust and corrosion resistant mounting points.
• Breathable design lets air and water pass through, reducing heat buildup beneath the sail.
• High UPF50 sun protection significantly lowers direct sunlight exposure and surface temperatures.

Cons

• Not waterproof, so it will not keep an area dry in steady rain or provide full weatherproof coverage.
• Size must be measured carefully before ordering; manual measurement variance can affect fit despite constant fabric area.
