Custom Size 19ft x 21ft Green Rectangle Sun Shade Sail - Tight

In this review of the Custom Size 19' x 21' Green Rectangle Sun Shade Sail the bottom line is simple: it is built for anyone who needs a tailored shade solution that stays taut and blocks sun effectively. The reviewer found the sail best for patios, pools, and carports where a precise fit matters, and highlights the curved edges and corner-to-corner measurements as the single biggest reason to choose it. Installation can be straightforward with planning, and the fabric's UV-blocking strength is the standout practical benefit.

Key Features

• Perfect Fit Measurements: Corner-to-corner sizing and pre-curved edges reduce sagging so the sail stays tight and looks clean over time.
• Durable Material: Made from virgin polyethylene, the fabric is lightweight yet strong for long-term outdoor use without easily tearing.
• UV Blocking: Blocks up to 95% of UV rays and about 90% of visibility to provide cooler, more comfortable shaded areas and added privacy.
• All-Season Use: Effective for summer sun protection, frost reduction overnight, and light rain coverage around patios and pools.
• Custom Local Manufacture: Each shade is made locally to size, which helps ensure on-time delivery and a closer fit to the intended attachment points.
• Warranty: Backed by a 3-year limited warranty that provides reassurance about durability and workmanship.

Who It's For

The Custom Size 19' x 21' Green Rectangle Sun Shade Sail is aimed at homeowners and small businesses who need a large, custom-cut shade for outdoor living areas, driveways, carports, or poolside spaces where conventional umbrellas or rigid awnings are impractical. It is especially useful when a tight, low-sag profile and strong UV protection are priorities.

It is less suitable for installations that require complete waterproofing in heavy storms or for buyers expecting a rigid structure; those customers should consider fixed awnings or hardtop shelters instead. People who want a ready-to-install universal size rather than a custom fit should also look elsewhere.

Pros & Cons

Pros

• High UV protection keeps covered areas noticeably cooler and reduces sun exposure.
• Custom corner-to-corner sizing and curved edges minimize sag and produce a neat, taut look.
• Strong, virgin polyethylene fabric balances lightweight handling with durability and expected multi-season life.
• Local manufacture and a 3-year limited warranty add confidence in fit and quality.

Cons

• Not fully waterproof for heavy rain or extended storms, so it provides only light rain coverage.
• Installation can be mixed in difficulty depending on anchoring points and site layout, requiring careful planning.
