Custom Size 21ft x 22ft White Rectangle Sun Shade Sail - UPF50

In this review of the custom size 21' x 22' white rectangle sun shade sail, the bottom line is clear: this canopy is for people who need tailored, heavy-duty sun protection for patios, playgrounds, or commercial outdoor spaces. The biggest reason to buy is its combination of 95% UV blockage from 200 GSM HDPE fabric and a construction focused on longevity, including stainless steel D-rings and reinforced edges. The sail cools shaded areas noticeably, installs with common mounting hardware, and is sold with a 3 year assurance that underscores its durability.

Key Features

• 95% UV protection: The 200 GSM HDPE material blocks up to 95% of harmful rays for safer outdoor use and reduced sun exposure.
• Temperature reduction: The canopy cuts ambient temperatures in shaded zones by up to about 15 degrees, making patios and seating areas more comfortable.
• Custom sizing: Measurements are taken from D-ring to D-ring so the sail fits a specific area rather than relying on approximate dimensions.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings help the sail resist fraying and endure heavy duty use.
• Water and air permeable: The knitted HDPE allows airflow and sheds some water while avoiding the ballooning that solid canopies can cause in wind.
• 3 year assurance: A multi-year assurance period gives extra confidence for residential and commercial installations.

Who It's For

This shade sail suits homeowners, small business owners and facilities managers who need a tailored cover for a deck, poolside, playground, or outdoor dining area and who value high UV protection and long-term durability. It works well where a cooler outdoor environment and a neat, neutral look matter, and where rigid structures are impractical.

Those who should look elsewhere include shoppers who want a fully waterproof fabric or a lightweight, temporary beach shade; this product is built as a heavy duty, breathable canopy for sustained outdoor use rather than a sealed awning for heavy rain runoff.

Pros & Cons

Is this shade sail waterproof?
It is water and air permeable, so it sheds light moisture but is not a fully waterproof, sealed canopy for heavy rain runoff.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each corner as instructed so the finished sail matches the exact span between anchors.

Will it withstand strong winds?
Customers report the material and reinforced fittings hold up well; proper tensioning and secure anchors are important for best wind performance.
