SUNNY GUARD Custom Size 12ft x18ft x21.66ft Peach Fuzz Right Triangle

In this review of the SUNNY GUARD custom size shade sail, the bottom line is simple: this is a practical, heavy-duty sunshade for homeowners who want reliable UV protection without a permanent structure. The reviewer found the 100% high density polyethylene fabric blocks up to 95% of harmful rays and the breathable weave helps keep spaces noticeably cooler. Intended for patios, decks, poolside areas or RV awnings, it offers a customizable fit and solid materials, making it a sensible, budget-friendly alternative to motorized or framed awnings.

Key Features

• UV Protection: The HDPE fabric blocks up to 95% of harmful UV rays, reducing sun exposure for people and furniture beneath the sail.
• Breathable Cooling: The breathable weave allows air to pass through so the covered area stays cooler than with solid canopies.
• Customizable Size: Custom sizing is available so the sail can be tailored to irregular outdoor spaces rather than forcing a standard fit.
• Durable Material: Made from high density polyethylene (185 GSM) without fabric splices, the sail feels sturdy and resists wear from sun and weather.
• Included Accessories: The package includes 3 to 4 thickened ropes for installation, allowing immediate setup while recommending stainless steel hardware for long-term durability.
• Versatile Use: The curved right triangle shape works for patios, pergolas, carports, pool areas and even RV awnings for flexible shade solutions.

Who It's For

This shade sail is well suited to homeowners, renters with outdoor spaces, and campers or RV owners who need a portable, effective sun barrier. Anyone who needs shade over a deck, sandbox, poolside seating, or BBQ area and wants to avoid a permanent build will appreciate the custom sizing and breathable fabric.

Those needing a motorized, retractable or fully waterproof canopy should look elsewhere; this sail is designed for sun and partial rain drainage thanks to its breathable HDPE material, not for full storm or waterproof sheltering.
