6 ft x 10 ft x 11.7 ft Black Right Triangle Sun Shade Sail - UV Block

In this review of the 6' x 10' x 11.7' Black Right Triangle Sun Shade Sail, the bottom line is simple: it is a practical, heavy-duty shade solution for homeowners who want reliable UV protection and good airflow without a permanent structure. The reviewer found it especially useful over pools, patios and carports because the fabric blocks up to 95% of UV while still allowing ventilation, and the curved-edge design prevents mid-span sagging for a neater, longer-lasting installation.

Key Features

• Corner-to-corner measurement: The sail is sized from corner to corner so buyers can match the canopy to an irregular area with predictable coverage.
• Curved edges: Precisely calculated radian curves on the edges reduce sagging in the middle and preserve a taut, attractive appearance once installed.
• Virgin polyethylene fabric: Lightweight but strong material gives good tensile strength for tensioned mounting and resists wear from regular outdoor use.
• High UV blockage: Provides up to 95% UV blockage and about 90% visibility blockage, keeping shaded areas cooler and protecting skin and surfaces.
• Seasonal versatility: The fabric allows cooling ventilation in summer, helps reduce frost overnight, and offers light rain resistance during wet weather.
• Customizable and warranted: Available for custom orders and backed by a 3-Year Limited Warranty for added confidence.

Who It's For

This shade sail is best for homeowners with patios, balconies, poolside decks, driveways, carports or gardens who need a flexible sun protection option that can be tensioned between trees, posts or anchors. It is particularly useful where airflow and heat reduction matter, such as over a swimming pool or outdoor seating area.

Those who require a fully waterproof awning, rigid installation hardware included with professional anchoring, or precise factory-fit structures for small architectural gaps may want to consider a different, more rigid solution. Also, if you need a pattern or translucent aesthetic rather than high UV blockage, look elsewhere.

Pros & Cons

Pros

• High UV protection and good airflow keep outdoor spaces noticeably cooler.
• Curved edge design prevents center sagging and improves long-term appearance.
• Durable virgin polyethylene gives strong tensile strength while remaining lightweight.
• Custom orders and a 3-Year Limited Warranty offer flexibility and reassurance.

Cons

• Hardware included receives mixed feedback, so buyers may want to upgrade mounting hardware for heavy-duty or permanent installs.
• Only slightly rainproof, so it is not a replacement for a full waterproof canopy in heavy rain.
