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

Our review of the custom size 21' x 22' green rectangle sun shade sail finds it is best for homeowners and small businesses who need heavy-duty, configurable shade without a permanent structure. The single biggest reason to buy is its combination of high UV blockage and durable construction: crafted from 200 GSM HDPE fabric that blocks up to 95% of UV rays and lowers ambient temperatures by up to 15 degrees, it provides reliable sun protection and noticeably cooler outdoor areas. Installation is flexible and the reinforced hardware and stitching deliver commercial-grade durability.

Key Features

• 95% UV Blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays for safer outdoor use and long-term protection.
• Temperature Reduction: The shade sail can reduce temperatures by up to 15 degrees compared with unshaded areas, improving comfort on hot days.
• Customizable Fit: Made to order using D-ring to D-ring measurements so the sail fits irregular spaces and can be tailored with straight edges on request.
• Durable Construction: Stainless steel D-rings, reinforced edges and double-layer stitching help prevent fraying and extend service life.
• Easy & Flexible Installation: Can be anchored to trees, roofs, walls or poles with mounting hardware kits and requires corner gaps as specified for optimal tension.
• Commercial Standard: Built to a heavy duty standard suitable for higher wind exposure and frequent use in patio and garden settings.

Who It's For

This shade sail is ideal for homeowners with patios, pergolas or open yards and for small businesses such as cafes or daycares that need a removable, larger-than-average canopy. Anyone who wants a custom-fit solution for an awkward space will appreciate the made-to-order sizing and the heavy-duty materials.

It is not intended for people seeking a fully waterproof awning or a permanent roof replacement; the fabric is water and air permeable, and installation still requires proper anchoring and tensioning to perform best in wind. Those needing a non-permeable or insulated cover should look elsewhere.
