Custom Size 17 ft x 20 ft Red Rectangle Sun Shade Sail - Tight Fit

In this review of the Custom Size 17' x 20' Red Rectangle Sun Shade Sail the bottom line is simple: this is a tailored outdoor shade for anyone who wants a neat, sag-free cover over patios, pools, or driveways. The product stands out because it is made to measure from corner to corner with curved edges that keep the fabric taut. For those prioritizing reliable UV blocking and a clean, finished look, this sun sail delivers a clear improvement over generic, one-size sails.

Key Features

• Perfect fit measurements: Corner-to-corner sizing and curved edges ensure the sail stays tight and resists sagging for a clean appearance.
• Durable UV-blocking material: Made from virgin polyethylene, the fabric is lightweight yet strong and reduces sun exposure for cooler shaded areas.
• High sun protection: Blocks up to 95% of UV rays and reduces visibility by about 90%, aiding cooling and privacy under the canopy.
• All-season use: Suitable for summer sun protection, nighttime frost reduction and light rain coverage, making it versatile year round.
• Custom sizes made locally: Each shade is custom-made to fit the intended space and delivered on time, avoiding awkward sizing compromises.
• 3-year limited warranty: Backed against defects for added confidence in long-term outdoor use.

Who It's For

The Custom Size 17' x 20' Red Rectangle Sun Shade Sail is best for homeowners and renters who need a large, tailored shade for a specific area like a patio, poolside, carport or balcony and value a neat installation with minimal sag. It suits anyone who wants strong UV protection and some added privacy without building permanent structures.

Those who should look elsewhere are buyers who need full waterproof roofing, very heavy snow load capacity, or an off-the-shelf quick-replace product; this sail is designed for light rain and seasonal use and is sold as a custom, fitted fabric solution rather than a rigid canopy.

Pros & Cons

Pros

• Custom corner-to-corner sizing and curved edges produce a tight, sag-resistant installation.
• Virgin polyethylene construction feels lightweight yet durable and blocks most UV to keep areas cooler.
• Made locally to order with a 3-year limited warranty, offering reliable delivery and support.
• Versatile for patios, pools, carports and balconies with good privacy thanks to reduced visibility.

Cons

• Not intended as a fully waterproof roof; performs best for sun, light rain and frost reduction rather than heavy storms.
• Installation can be mixed in difficulty depending on mounting points and hardware, so some customers may need extra time or help.
