Custom Size 11ft x 11ft x 15.6ft Right Triangle Sun Shade Sail - UPF50

In this review of the Custom Size 11' x 11' x 15.6' Right Triangle Sun Shade Sail, the verdict is straightforward: it is a practical, customizable shade solution for homeowners and small businesses who need reliable sun protection without permanent construction. The biggest reason to consider it is its combination of 95% UV blockage and tailored sizing, which makes the sail useful where standard sizes or rigid structures do not fit. Installation is flexible and the material is substantial, so it suits patios, play areas, and outdoor seating that need cooler, shaded coverage.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect skin and reduce sun exposure.
• Temperature Reduction: The shade sail lowers ambient temperatures by as much as 15 degrees compared with unshaded areas for more comfortable outdoor time.
• Custom Fit: The sail is made to order with measurements taken D-ring to D-ring so the canopy matches irregular spaces and mounting points.
• Durable Construction: Reinforced edges, double-layer stitching, and stainless steel D-rings add strength for longer service life in outdoor conditions.
• Breathable and Drains: The HDPE weave is water and air permeable, which helps prevent ponding and reduces wind stress on the fabric.
• Installation Flexibility: Can be mounted to trees, roofs, walls or poles and allows corner spacing adjustments to suit existing anchors.

Who It's For

Homeowners with patios, decks, or poolside seating who need a custom-shaped shade that fits nonstandard anchor points will find this sail a good match. Small commercial spaces such as cafe patios and play areas that want effective UV protection and temperature reduction without a permanent pergola will also benefit.

Customers who want a maintenance-free, permanent cover or who expect decade-long fabric life in very harsh sun may want to consider heavier commercial canopies or hard structures, since some users report mixed long-term durability in extreme exposure.

Frequently Asked Questions

Is this sail suitable for light rain?
Yes - the HDPE fabric is water permeable so it sheds water without ponding, but it is not a waterproof tarp for heavy downpours.

How should I size the sail for existing anchors?
Provide precise D-ring-to-D-ring measurements; allow at least 0.5 ft gap between D-rings and poles or reduce by 1 to 1.5 ft per side if needed for tensioning.

How long does the fabric last outdoors?
Material is built for outdoor use and comes with 3 years assurance, though longevity can vary by sun intensity and local climate; some users report good life beyond a year while others in extreme sun saw earlier wear.
