13 ft x 17 ft x 21.4 ft Turquoise Right Triangle Shade Sail - Cool UV

Our review of the 13 ft x 17 ft x 21.4 ft Turquoise Right Triangle Shade Sail finds it best for homeowners who need strong, reliable sun protection for a patio, pool area, or driveway. The single biggest reason to buy is its engineered shape and material: measurements are taken corner to corner and the edges are slightly curved using a calculated radian to prevent sagging, which keeps the canopy taut and visually neat while delivering up to 95% UV blockage.

Key Features

• Curved edge design: Precisely calculated radian on the edges prevents sagging in the middle for a clean, tensioned appearance and consistent performance.
• High UV protection: The virgin polyethylene fabric blocks up to 95% of UV rays while still allowing air flow for cooling and ventilation.
• Visibility reduction: Approximately 90% visibility blockage offers privacy and sun shading without creating a closed-off feel.
• Weather versatility: Lightweight but strong material provides summer cooling, night anti-frost protection and slight rain resistance during light showers.
• Customizable sizing: The manufacturer offers custom orders so the sail can be tailored to irregular spaces or tree-to-post installs.
• Limited warranty: Comes with a 3-Year Limited Warranty for added purchase confidence.

Who It's For

This shade sail suits homeowners with outdoor areas such as backyards, patios, carports, or pool decks who want a durable, effective canopy that installs between posts or trees. It's particularly useful where a triangular coverage area is preferred to avoid obstructing sight lines or to work with existing structures.

People who need fully waterproof canopies or a rigid structure should look elsewhere, since this is a fabric sail designed for shading, ventilation and light rain resistance rather than full waterproof shelter or winter storm protection.

Pros & Cons

Pros

• Effective sun protection with up to 95% UV blockage, keeping areas noticeably cooler.
• Curved edge construction maintains tension and reduces midspan sag over time.

• Custom order option and a 3-Year Limited Warranty provide flexibility and assurance.

Cons

• Hardware is included but reviews are mixed, so buyers may want to confirm mounting needs or upgrade fittings for heavier installations.
• Only slightly rainproof, not suitable as a full waterproof awning in heavy rain.
