SUNNY GUARD Custom Size 17ft x17ft x17ft Shade Sail Triangle - UV

In this review of the SUNNY GUARD Custom Size 17ft x17ft x17ft Terra Sun Shade Sail, the bottom line is simple: this is a practical, customizable shade solution for homeowners and outdoor hosts who want reliable UV protection without a bulky permanent structure. The sail's standout attribute is its high density polyethylene fabric that blocks up to 95% of harmful UV rays while remaining breathable, so it reduces direct sun exposure yet still lets air move. Installation is straightforward for someone comfortable with basic mounting points and ropes, and the option for custom sizing makes it especially useful for odd-shaped patios and deck areas.

Key Features

• UV Protection: The high density polyethylene material blocks up to 95% of harmful UV rays, providing strong sun protection for people and furnishings beneath it.
• Cooling Breathability: The fabric is breathable, allowing air to pass freely so the shaded area feels noticeably cooler than full sun.
• Customizable Size: Available in custom sizes to fit irregular spaces, the 17ft x17ft x17ft triangle example suits larger yards, patios, or poolside areas.
• Durable Construction: Made without spliced fabrics and supplied with thickened ropes, the sail feels sturdy and resists wear from sun and weather.
• Installation Guidance: The product includes advice to leave a 0.5-1 ft margin for mounting hardware and provides measurement instructions to simplify fitting.
• Made in USA: The sail is made in the USA and the brand offers customer contact to help with custom orders.

Who It's For

The SUNNY GUARD shade sail is ideal for homeowners with patios, decks, pergolas, pools, BBQ areas or RV awnings who want an affordable, low-profile way to add reliable sun protection and cooling. It fits people who need a tailored fit, since custom sizing avoids awkward gaps or unnecessary fabric.

This is less suited for buyers who need a retractable or motorized solution, or those who prefer a fully rigid awning. Also, if you cannot add sturdy anchor points or prefer a permanent hard canopy, a fabric shade sail may not meet your needs.

Pros & Cons

Pros

• Blocks a high percentage of UV rays while remaining breathable for cooling comfort.
• Custom sizing options let it fit unusual outdoor layouts and larger open areas.
• Durable feel and supplied ropes make initial setup manageable and long lasting.
• Good value compared with larger permanent awnings and easy to remove seasonally.

Cons

• Requires proper anchor points and possibly additional stainless steel hardware for maximum durability.
• As a fabric solution it is not a permanent rigid structure and may move in very strong winds.
