SUNNY GUARD Shade Cloth 4x21 ft Custom Size - 95% UV Block

Our review of the SUNNY GUARD 4x21 ft custom shade cloth finds it best suited for homeowners and gardeners who need robust, breathable sun protection for pergolas, patios or plant beds. The single biggest reason to consider this shade sail is its combination of heavy-duty HDPE fabric and reinforced copper grommets that make mounting straightforward while reliably blocking about 95% of direct sunlight. In daily use it balances privacy, airflow and light transmission, making outdoor spaces noticeably cooler without completely cutting visibility.

Key Features

• 95% Sun Block: The fabric blocks most direct sunlight to reduce heat and protect plants and furnishings from intense UV exposure.
• Durable HDPE Construction: Knit HDPE resists tearing and abrasion so the cover stands up to regular outdoor use.
• Double Reinforced Edges: Each edge is reinforced to prevent fraying and extend the life of the cloth under tension.
• Copper Grommets Every 2 ft: Rust-resistant metal grommets make it easy to secure and tension the shade using ropes or zip ties.
• Breathable Design: The weave allows airflow and some light transmission so the area remains ventilated and not completely dark.
• Custom Size Option: The product can be customized to specific dimensions for tailored coverage of odd-shaped areas.

Who It's For

This shade cloth is ideal for homeowners with pergolas, patios, decks or pools who want a straightforward way to reduce sun and heat without installing a permanent structure. Gardeners and those with outdoor plantings will appreciate a breathable fabric that offers reliable shade while still allowing air circulation.

It may be less suitable for people seeking a decorative sail with precise sun angle control or those who need a fully waterproof tarp; this is a shade fabric designed for UV and heat reduction rather than full rain protection.

Pros & Cons

Pros

• High shade effectiveness and good value for the material and size.
• Sturdy knit HDPE fabric with reinforced edges resists tearing under tension.
• Easy to install using the included grommets and common fasteners like bungee cords or zip ties.

Cons

• Size expectations can vary between buyers, so custom sizing or careful measuring is important.
