Sun Shade Sail Triangle 17ft x 22ft x 22ft - Breathable UV Block

In this review of the SUNN Y GUARD sun shade sail, the bottom line is simple: it is a practical, budget-friendly shade solution for homeowners who need broad UV protection without complex installation. The reviewer found the triangular sail effective at blocking sunlight, breathable enough to reduce direct heat, and robustly built for outdoor use. This review focuses on usability, materials and real-world performance for backyard patios, pools and RV awnings so buyers know what to expect before measuring and installing.

Key Features

• UV Protection: The high density polyethylene fabric blocks up to 95% of harmful UV rays, providing reliable sun protection for people and furnishings.
• Breathable Cooling: The breathable weave allows air and some water to pass through, helping lower temperature under the sail on hot days.
• Durable Construction: Made from single-piece 185GSM HDPE material without spliced seams, which improves longevity in sun and wind compared with thin spliced options.
• Customizable Size: The brand offers custom sizing to fit irregular outdoor spaces, making it easier to cover patios, decks or poolside areas.
• Installation Accessories: Basic ropes are included for setup, and users can upgrade to stainless steel fittings for longer-lasting anchors.
• Warranty and Support: Made in USA with a five year warranty under normal use, and direct customer support is available for fit or installation questions.

Who It's For

The SUNN Y GUARD triangle shade sail is a good fit for homeowners and renters who want an economical, low-profile way to create shade over a patio, deck, pool, sandbox or RV area. It suits DIY installers who can measure anchor points and leave 0.5 to 1 ft of slack for hardware and rope.

It is less suited for those who want a fully waterproof canopy, a motorized retractable system, or a ready-made mounting kit; buyers who need stainless steel turnbuckles and heavy-duty hardware should plan to purchase those separately for the most durable installation.

Pros & Cons

Pros

• Blocks a high percentage of UV rays while remaining breathable, so shaded areas stay cooler.
• Constructed from single-piece 185GSM HDPE material, which customers report holds up in strong sun and storms.
• Custom sizing and included ropes make it flexible for nonstandard areas.

Cons

• Included rope is basic; for long-term durability buyers should invest in stainless steel fittings and stronger anchors.
• Not a waterproof solution, so it will not fully block heavy rain.
