Sun Shade Sail Triangle 13ft x 20ft x 20ft Turquoise Blue - UV Block

In this review of the SUNN Y GUARD sun shade sail, the bottom line is simple: if you want a straightforward, durable shade solution for a backyard, patio, pool or RV awning, this sail delivers strong UV protection and a cool, breathable cover at a modest price. The reviewer found it effective at blocking sun and reducing heat while staying breathable enough for airflow; its 95% UV block claim and high density polyethylene fabric translate to tangible daytime comfort. Installation is mostly simple with the supplied ropes, and customers appreciate the sturdy construction and clean modern look.

Key Features

• UV Protection: Blocks up to 95% of harmful UV rays so shaded areas stay cooler and skin exposure is reduced.
• Breathable Fabric: The high density polyethylene material allows air and some water to pass through, reducing heat buildup beneath the sail.
• Durable Construction: Made from 185GSM HDPE without spliced panels to improve longevity and hold up in stormy, hot conditions.
• Customizable Size: Available in custom sizes so the sail can be tailored to fit irregular patios, decks, or carports.
• Included Accessories: Ships with 3 or 4 thick ropes depending on shape to get you started with installation.
• Versatile Use: Works well over pools, pergolas, sandboxes, RV awnings and BBQ areas for a wide range of outdoor needs.

Who It's For

This shade sail is best for homeowners and renters who need an economical, attractive way to add shade to outdoor living spaces such as patios, decks, pools, and driveways. It suits people who prefer a low-maintenance, fixed fabric solution rather than mechanical awnings and who value UV protection and airflow.

Those looking for a fully waterproof canopy, motorized adjustment, or an ultra-heavy commercial installation should look elsewhere; this product is designed as a breathable, UV-blocking sail rather than a watertight or permanently mounted structure.

Pros & Cons

Pros

• Effective UV blocking and measurable cooling effect under the sail.
• Sturdy HDPE fabric and reinforced edges provide good durability in sun and wind.

• For long-term durability, additional stainless steel hardware is recommended beyond the supplied ropes.
