SUNNY GUARD 13ftx13ftx18.4ft Right Triangle Sun Shade Sail

In this review of the SUNNY GUARD Custom Size 13'x13'x18.4' Right Triangle Sun Shade Sail, the bottom line is simple: it is a practical, heavy-duty shade solution for homeowners who want reliable UV protection and cooler outdoor spaces without complex structures. The reviewer found the sail best for patios, pools, decks, and RV awnings where straightforward coverage, good airflow and lasting material matter most, and highlights the product's ability to block up to 95% of harmful UV while remaining breathable and durable.

Key Features

• High density material: The 185GSM high density polyethylene fabric delivers robust durability and resists rapid wear in sun-exposed installations.
• UV protection: Rated to block up to 95% of UV rays, the sail reduces direct sunlight exposure for people and furniture beneath it.
• Breathable design: The mesh-like fabric allows air and some water to pass through, helping keep covered areas cooler and preventing water pooling.
• Custom sizing: SUNNY GUARD offers custom sizes so the right triangle 13'x13'x18.4' option can be tailored to irregular outdoor layouts.
• Included installation ropes: The package includes 3 to 4 thickened ropes for initial installation, making setup quicker for most DIY users.
• Made in USA: Manufactured domestically, which can matter for buyers wanting locally made outdoor products.

Who It's For

This shade sail is ideal for homeowners and renters who need a low-profile, cost-effective way to add sun protection to a backyard, patio, pool area, carport, pergola or RV awning. It suits people who prefer a breathable fabric that reduces heat while preventing water pooling and who appreciate the option of custom sizing to fit odd-shaped spaces.

Less suitable are buyers seeking a fully waterproof canopy, motorized retractable systems, or a shade requiring no anchoring hardware; for those needs a dedicated waterproof awning or professional hard-structure installation would be a better fit.

Pros & Cons

Pros

• Solid UV protection that blocks most harmful rays and keeps areas cooler in hot weather.
• Breathable fabric that prevents water buildup and reduces wind load compared with solid covers.
• Custom sizing and included ropes make it easy to match the sail to specific outdoor layouts.

Cons

• Not fully waterproof, so it will not provide complete rain shelter in heavy downpours.
• Durability depends on mounting hardware; additional stainless steel accessories are recommended for long-term installations.
