17ft x 20ft x 26.2ft Blue Right Triangle Sun Shade Sail - UPF50

In this review the reviewer found the 17' x 20' x 26.2' blue right triangle shade sail best suited for homeowners and small commercial spaces that need strong sun protection without a permanent structure. The most convincing reason to buy is its reliable 95% UV blockage from heavy 200 GSM HDPE fabric, which noticeably cools shaded areas and stands up to summer sun and wind. Installation is flexible enough for trees, walls or posts, and the reinforced edges and stainless steel D-rings give confidence the canopy will last.

Key Features

• 95% UV Protection: The 200 GSM HDPE material blocks up to 95% of harmful UV rays for safer outdoor time.
• Temperature Reduction: The sail can lower ambient temperature by about 15 degrees compared to unshaded areas, making patios and play areas more comfortable.
• Custom Fit: Orders are made to measure from D-ring to D-ring so the sail fits the intended span and can be customized on request for straight edges.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity and resist fraying under load.
• Water and Air Permeable: The woven HDPE lets water and air pass through to reduce wind sail and pooling while still providing shade.
• 3 Year Assurance: The product includes a 3 year assurance that backs the material and construction quality.

Who It's For

This shade sail is ideal for people who need a semi-permanent, adaptable sunshade over patios, play areas, small commercial seating or animal enclosures. It works well for those who want measurable sun protection and a cooler shaded space without building a permanent roof. The customizable sizing is useful for awkward or nonstandard areas where off-the-shelf sails fall short.

Those who need a full waterproof canopy, a completely rigid structure, or very large continuous coverage for commercial canopies should look elsewhere. Also, buyers should double-check measurements carefully since some customers noted the delivered sail felt smaller than expected when measurements were not precise.

Pros & Cons

Pros

• High UV blockage that provides reliable protection and helps reduce heat under the sail.
• Sturdy build with reinforced hems, double stitching and stainless steel D-rings for secure mounting.
• Custom sizing and the option to request straight edges make it flexible for irregular spaces.
• Permeable design avoids water pooling and reduces wind load compared with solid covers.

Cons

• Some buyers found the delivered sail smaller than expected, so strict measurement and communication are required.
• Not fully waterproof, so it will not replace a sealed canopy in heavy rain.
