SUNNY GUARD Sun Shade Sail Triangle 16ft x 20ft x 25.6ft - Cool UV

In this review of the SUNNY GUARD sun shade sail, the bottom line is simple: this triangular turquoise blue sail is for anyone who wants reliable, breathable UV protection for patios, decks, poolside areas or RV awnings without a permanent structure. The reviewer found it especially useful in hot, sunny climates because the high density polyethylene fabric blocks up to 95% of harmful rays while still allowing air and water to pass through, producing a noticeable cooling effect. Installation is straightforward for a weekend DIYer, and the option for custom sizing makes it adaptable to irregular spaces.

Key Features

• UV protection: The sail is made from high density polyethylene that blocks up to 95% of harmful UV rays, reducing sun exposure for people and furniture.
• Breathable cooling fabric: The material lets air circulate and water drain, so shaded areas stay cooler and do not collect puddles after light rain.
• Customizable sizing: SUNNY GUARD offers custom sizes so the sail can be fitted to awkward or specific outdoor layouts for a cleaner installation.
• Included installation ropes: The package includes 3-4 thickened ropes for mounting, enabling immediate setup for typical triangle and square configurations.
• Durable construction: Heavy duty 185 GSM fabric and reinforced edges make the sail hold up well during storms and extended sun exposure.

Who It's For

This sun shade sail is best for homeowners with patios, decks, pool areas, backyards or pergolas who want a cost-effective, semi-permanent shade solution. It is also a good fit for RV owners and people who need shade over outdoor dining or BBQ areas and appreciate a modern look without building a permanent canopy.

Those who should look elsewhere include shoppers seeking a fully waterproof canopy or a motorized retractable awning, and buyers who need a rigid structure with wind sensors and automated tensioning. If you need headroom for frequent high winds, consider a framed option instead.

Pros & Cons

Pros

• High UV block rate keeps shaded areas noticeably cooler and protects skin and outdoor fabrics.
• Breathable mesh design drains water and allows airflow, avoiding heat pockets under the sail.

Cons

• Not fully waterproof, so it will not provide complete protection in heavy rain.
