Custom Size 17ft x 19ft x 25.5ft Right Triangle Sun Shade Sail - Cool

In this review of the custom size right triangle sun shade sail the bottom line is straightforward: it is for homeowners and outdoor spaces that need a durable, high-coverage shade solution with strong UV protection. The sail's biggest selling point is its practical balance of heavy-duty 200 GSM HDPE construction and measurable heat reduction, which together deliver reliable shade for patios, pools, and backyard seating areas. Reviewers who wanted an adjustable, long-lasting canopy found it effective and easy to fit to existing posts, roofs, or trees.

Key Features

• 95% UV blockage: The fabric blocks up to 95% of harmful UV rays to protect people and furniture underneath from sun damage.
• 200 GSM HDPE construction: A thicker, commercial-grade weave gives the sail strength to resist fraying and hold up in sun and wind.
• Temperature reduction: The shade can lower ambient temperatures by up to 15 degrees compared with unshaded areas for a noticeably cooler outdoor space.
• Customizable fit: Made to measured D-ring to D-ring dimensions so customers get a tailored fit for unusual or specific layouts.
• Reinforced hardware: Stainless steel D-rings and double-layer stitching at edges increase longevity and fastening security.
• Easy installation: The sail can be mounted to trees, roofs, walls, or poles using common hardware kits and simple spacing guidelines for each corner.

Who It's For

This shade sail suits homeowners, rental property owners, and operators of small commercial outdoor spaces who need strong sun protection and a custom-sized fit for awkward shapes or nonstandard layouts. It is especially useful where a permanent pergola is not desired but reliable, long-term shade is needed.

People who want an inexpensive one-size-fits-all tarp or who need a fully waterproof canopy should look elsewhere; the fabric is water and air permeable, so it breathes and sheds some water but is not a waterproof shelter for continuous exposure in heavy rain.

Pros & Cons

Pros

• High sun protection with up to 95% UV blockage for safer outdoor use.
• Durable 200 GSM HDPE material and reinforced edges resist fraying and heavy sun exposure.
• Measurable temperature reduction creates a more comfortable shaded area.
• Custom sizing and stainless steel D-rings make it adaptable to many mounting arrangements.

Cons

• Not fully waterproof because the material is water and air permeable, so expect some drip-through in rain.
• Some buyers report size perceptions vary, so precise measurement from D-ring to D-ring is important to avoid surprises.

Frequently Asked Questions

Is this sail waterproof?
The fabric is water and air permeable, so it is not fully waterproof; it sheds some water but allows airflow and light drainage.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each side and allow at least 0.5 ft gap between D-rings and poles; reduce by 1 to 1.5 ft per side if required by your mounting points.

Does it include mounting hardware?
The product is compatible with common mounting hardware kits, but customers should confirm specific hardware is provided or obtain suitable kits for their installation.
