13 ft x 20 ft x 23.9 ft White Right Triangle Shade Sail - Heavy Duty

In this review the Royal Shade right triangle shade sail is evaluated for homeowners and commercial users who need a durable, well-fitting sun cover. The bottom line: this custom-size, 100% 200 GSM HDPE mesh sail is best for patios, play areas, and dog runs where strong UV protection and breathability matter. The reviewer found it blocks most sun while allowing airflow, and the slightly curved edges and reinforced corners make installation neat and tensioned, so the sail stays tight rather than sagging in the middle.

Key Features

• Custom corner-to-corner measurement: Precise corner measurements and a calculated curved edge help the sail fit tautly and maintain a clean appearance after installation.
• 200 GSM HDPE fabric: The woven knitted material blocks up to 95% of harmful UV while remaining breathable so water and breeze pass through, reducing pooling and wind load.
• Reinforced finished edges: Heavy duty double layered stitched seams prevent fraying and keep the sail shape stable over time.
• Stainless steel D rings: Each corner has a stainless D ring with extra stitched reinforcement, making attachment to poles, walls, or hardware kits secure and straightforward.
• Three year UV warranty: Built-in UV inhibitors and a 3 year warranty against UV degradation give confidence for regular sun exposure.

Who It's For

This shade sail is suited to homeowners, small businesses, and property managers who want a robust, breathable sun cover for patios, playgrounds, or pet areas. It performs well where a neat, tensioned installation is important and where some water passage is preferred to avoid pooling.

Those who need a perfectly straight-edged look or require a different fabric weight or waterproof canopy should consider a custom straight-edge order or another product; also, buyers wanting a fully waterproof solution should look at non-breathable canopies instead.

Pros & Cons

Pros

• Durable 200 GSM HDPE material that provides strong UV block while remaining breathable.
• Curved-edge design and corner D rings result in a tight, neat installation that resists sagging.
• Reinforced seams and stainless hardware increase longevity and reliability in normal weather.

Cons

• Not fully waterproof since the breathable fabric allows water and breeze to pass through.
• Size expectations vary; some customers reported the chosen size felt smaller than expected, so careful measurement is necessary.

Frequently Asked Questions

How is the sail measured?
Measurement is taken from corner to corner and edges are cut with a slight curve to ensure a tight, neat fit after installation.

Will the fabric keep water out?
The 200 GSM HDPE mesh is breathable so it allows water and breeze to pass through, which prevents pooling but does not make it fully waterproof.

What hardware is needed to install?
Stainless D rings are provided at each corner; use poles, cable wires, turnbuckles, or compatible hardware kits to create tension and space between D rings and anchor points.
