Sun Shade Sail Triangle 13ft x 20ft x 23.9ft - UV Block & Cooling

In this review of the SUNNY GUARD sun shade sail, the bottom line is simple: it is a straightforward, heavy-duty shade solution for homeowners and small businesses who need reliable UV protection without complex installation. The reviewer found the triangular sail to block sunlight effectively while remaining breathable enough to allow air flow and reduce ambient temperature. This makes it a solid choice for patios, decks, poolside seating, and RV awnings where durable, budget-friendly shade is the priority.

Key Features

• High density material: Made from 100% new high density polyethylene, the fabric resists tearing and feels substantially more robust than thin alternatives.
• UV protection: The sail blocks up to 95% of harmful UV rays, providing meaningful sun protection for outdoor seating and play areas.
• Breathable design: The woven fabric allows air and water to pass through, helping lower temperatures underneath the sail and preventing water pooling.
• Custom sizing: SUNNY GUARD offers custom sizes so the sail can be tailored to nonstandard patios, decks, and garden layouts.
• Accessories included: Triangle shipments include three pieces of rope for mounting, which covers basic installs and lets users get the sail in place quickly.
• Made in USA with warranty: Built in the USA and backed by a five year warranty under normal use and weather, giving extra confidence in durability.

Who It's For

This shade sail is a good fit for homeowners with a patio, deck, pool area, sandbox or BBQ spot who want a durable, no-fuss canopy that reduces sun exposure and helps cool a small outdoor zone. It is also useful for RV owners or carport users who need an affordable, portable shade option with sturdy D-rings and included ropes for straightforward attachment.

Those who want a retractable motorized system, an exact architectural fit without custom ordering, or a fully waterproof permanent roof should look elsewhere. For basic to moderate outdoor shading needs where UV blocking and airflow matter most, this sail is a practical choice.
