Custom Size 15 ft x 18 ft x 23.4 ft Right Triangle Shade Sail - Cooler

Our review of this custom size right triangle shade sail finds it best for homeowners or small businesses wanting a tailored shade solution that blocks harsh sun while staying breathable. The largest single reason to buy is its combination of heavy-duty 200 GSM HDPE fabric and 95% UV blockage, which delivers meaningful temperature reduction and long-term durability without creating a sealed, hot space. It is a practical, custom-fit canopy for patios, play areas, or poolside shade where effective sun protection and a clean look matter.

Key Features

• 95% UV Blockage: The fabric blocks up to 95% of harmful UV rays so shaded areas stay safer for extended outdoor use.
• 200 GSM Commercial Material: Heavy-duty HDPE construction resists tearing and maintains shape under wind and sun for dependable longevity.
• Temperature Reduction: The sail lowers ambient temperature by as much as 15 degrees versus unshaded spots, making outdoor time more comfortable.
• Custom Size From D-Ring to D-Ring: Measured to your exact D-ring distances, the sail provides a tailored fit so edges align with posts, walls, or trees.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching at the corners improve strength and reduce fraying over time.
• Permeable Design: The water and air permeable weave prevents ponding and allows airflow while still providing strong sun protection.

Who It's For

This shade sail suits homeowners, cafes, and small commercial spaces that need a custom-cut right triangle canopy to fit awkward or asymmetrical outdoor areas. It is especially useful where high UV protection and heat reduction matter, such as children's play areas, patios, pool edges, and outdoor seating.

Those who should look elsewhere include buyers who want a completely waterproof awning or a rigid-roof structure, since this product is water permeable and designed to provide shade and airflow rather than full rain protection. Also, buyers expecting off-the-shelf exact measurements without custom measurement from D-ring to D-ring may find the ordering process requires more planning.

Pros & Cons

• Permeable weave prevents water pooling and allows airflow, reducing heat build-up under the sail.

Cons

• Some customers note size expectations can differ, so careful measurement is required before ordering.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring at each corner and provide those precise distances when ordering for the correct fit.

Will the sail stop rain?
No, the HDPE fabric is water permeable to avoid ponding and allows airflow, so it reduces sun and heat but is not fully waterproof.

What hardware is recommended for installation?
Use sturdy posts, walls, or trees with appropriate mounting kits and allow about 0.5 ft gap between D-rings and poles, or reduce by 1 to 1.5 ft per side for tensioned installs.
