6 ft x 11 ft x 12.5 ft White Right Triangle Sun Shade Sail - Durable

Our review of this right triangle shade sail finds it best suited for homeowners and renters who need a lightweight, high-coverage solution to cut sun and heat in outdoor living spaces. The single biggest reason to buy is its effective material and shape: made from virgin polyethylene with curved edges measured corner-to-corner, the sail blocks up to 95% of UV while staying taut and resisting mid-span sag for a neater appearance. This makes it a practical choice for patios, pools, carports and gardens where cooling and sun protection matter.

Key Features

• Corner-to-corner measurement: The stated dimensions are taken from corner to corner so buyers can plan mounting points accurately for the triangular layout.
• Curved edge design: Edges are slightly curved based on a precise radian to prevent sagging and keep the sail looking tight and performing consistently over time.
• Virgin polyethylene fabric: The material is lightweight with strong tensile strength, which helps the sail resist wind strain while remaining easy to handle during installation.
• High UV and visibility blockage: Offers up to 95% UV blockage and about 90% visibility blockage, improving shade and cooling under the canopy.
• Seasonal versatility: Provides shading and ventilation in summer, helps reduce frost exposure at night, and is slightly rainproof during light rain.
• Warranty and customization: Comes with a 3-Year Limited Warranty and the option to request custom sizing if the stock size does not fit the space.

Who It's For

This shade sail is aimed at people who need broad, economical sun protection for outdoor areas like backyards, patios, swimming pool decks, carports and driveways. It is a good fit for DIY installers who can use existing posts, trees or house anchors to tension the sail and appreciate a fabric that balances strength with lightweight handling.

Those who should look elsewhere include buyers who need a fully waterproof awning for heavy rain, a permanent structural canopy, or a decorative solution that requires complex patterns or multiple integrated panels. Also consider professional shade systems if wind load certification and heavy-duty metal frames are required.
