11ft x 13ft x 17ft White Right Triangle Sun Shade Sail - Durable UV

In this review the 11' x 13' x 17' white right triangle sun shade sail is assessed for backyard and poolside use; the bottom line is that it is a practical, heavy-duty option for anyone wanting broad UV protection without a permanent structure. The reviewer found it best for homeowners who need a lightweight, ventilated canopy that blocks most sun and reduces heat. Measurements are taken corner to corner and the curved edges are designed to prevent sagging, so the canopy keeps a tidy, effective profile once tensioned.

Key Features

• Corner-to-corner measurement: The size is specified from corner to corner so buyers can plan anchor points precisely for a true triangular fit.
• Curved edges: Edges are slightly curved using a calculated radian to prevent middle sagging and maintain a taut appearance when installed.
• Material strength: Made from virgin polyethylene, the fabric offers strong tensile strength while remaining light enough for easy handling and positioning.
• UV and visibility blockage: The sail provides up to 95% UV blockage and 90% visibility blockage to significantly reduce sun exposure and glare.
• Seasonal versatility: The fabric shades and cools in summer, offers some anti-frost benefit at night, and is slightly rainproof in light wet weather.
• Custom orders and warranty: The manufacturer accepts custom sizes and includes a 3-Year Limited Warranty for added confidence.

Who It's For

This shade sail suits homeowners and renters who need a removable, non-permanent canopy for patios, decks, pools, carports, or gardens and who value strong sun blocking and airflow. It is especially useful where tree anchors or existing posts allow triangular installations that benefit from the corner-to-corner sizing.

It is less appropriate for buyers who need full waterproofing in heavy rain or a rigid, permanent roof structure; those who require exact factory-finished hardware fit for very high-wind coastal locations should consider a more specialized solution.

Pros & Cons

Pros

• High UV protection keeps outdoor areas noticeably cooler and reduces sun exposure.
• Curved edge design prevents sagging, producing a neat, functional canopy when tensioned correctly.
