Custom Size 11ft x 13ft x 17ft Right Triangle Sun Shade Sail - 95% UV

In this review the reviewer examines the custom size 11' x 13' x 17' right triangle sun shade sail and concludes it is a practical solution for homeowners and small commercial spaces needing reliable sun protection. The single biggest reason to buy is the material performance: made from 200 GSM HDPE it blocks up to 95% of UV and noticeably lowers ambient temperature, making it well suited for patios, play areas, and animal enclosures.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks harmful rays to provide shade and reduce sun exposure for people and belongings.
• Temperature reduction: In shaded areas the sail can lower temperatures by up to 15 degrees compared to unshaded spots, improving comfort on hot days.
• Custom fit: The sail is made to order from D-ring to D-ring so it can be tailored to specific spaces and adjusted for tension and clearance.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings contribute to longer service life under regular outdoor use.
• Water and air permeable: The woven construction helps vent heat and shed water while preventing the sail from becoming a solid barrier in wind.
• Simple installation guidance: The product ships with recommendations for corner clearance and can be attached to trees, poles, walls or roofs using common mounting hardware.

Who It's For

The shade sail is a good match for homeowners, renters with fixed anchor points, small commercial patios and people who need a custom-sized triangular cover rather than generic rectangles. It performs well where durability and measured fit matter, such as over seating, play areas or animal runs.

Those who should look elsewhere include buyers who expect a fully waterproof canopy or an off-the-shelf standard size that arrives ready to hang without any measurement or planning. Also, if an exact pre-cut size is not acceptable, consider other fixed-size options.

Pros & Cons

Pros

• High UV blockage provides strong sun protection and helps reduce heat beneath the sail.
• Sturdy materials and reinforced stitching with stainless D-rings add to long-term durability.
• Custom sizing from D-ring to D-ring allows a tailored fit for irregular or specific spaces.
• Permeable fabric vents air and water, reducing wind strain and pooling.

Cons

• Some customers have noted the ordered size can feel smaller than expected, so precise measurement is critical.
• Not fully waterproof, so it will not keep space completely dry in heavy rain.

Frequently Asked Questions

Is the sail waterproof?
The fabric is water and air permeable, so it sheds some water but is not fully waterproof for keeping an area completely dry.

How should I measure for a custom sail?
Measure from D-ring to D-ring and allow the recommended corner gap; the maker customizes to those D-ring dimensions for a tailored fit.

Will it withstand wind and sun?
Yes, the 200 GSM HDPE with reinforced edges and stainless D-rings is designed for durability in sun and typical winds, though proper tensioning and anchors are important.
