20 ft x 20 ft x 28.3 ft Right Triangle Sun Shade Sail - 95% UV Block

In this review the reviewer looks at a large custom-size shade sail designed for backyard and commercial outdoor shade. The bottom line: this product is for anyone who needs heavy sun protection in a specific triangular footprint and values durability and a tailored fit. It stands out because the 200 GSM HDPE fabric blocks up to 95% of UV and can lower ambient temperatures by up to 15 degrees, making it an effective, long-lasting cover for patios, play areas, or animal enclosures.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays, reducing sun exposure for people and pets beneath the sail.
• Temperature reduction: In direct comparison to unshaded areas the sail can lower local temperature by about 15 degrees, making outdoor time more comfortable.
• Custom measurements: The sail is made to order using D-ring to D-ring dimensions so it can be tailored to a specific space rather than relying on standard sizes.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity and resistance to fraying under regular outdoor use.
• Permeable design: The fabric is water and air permeable so it reduces heat and sun while allowing airflow and some water to pass through, reducing wind loading.
• Easy installation guidance: The sail can be attached to trees, walls, roofs or poles and the instructions note corner gap recommendations for correct tensioning and performance.

Who It's For

This shade sail is well suited to homeowners, small business operators and hobby farmers who need a large, triangular shade that can be custom-sized to fit an awkward area. It works well over patios, playgrounds, chicken runs and outdoor seating where strong UV protection and temperature reduction are priorities.

It is less appropriate for buyers who expect an off-the-shelf rectangle or very small square sail; several customers noted sizing can appear small if dimensions are misunderstood, so those who need standard small shades or who cannot measure between D-rings precisely should consider a different product.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring at each corner location and allow the recommended corner gap (about 0.5 ft) or reduce by 1 to 1.5 ft per side if needed for tensioning.

Will it protect from rain?
The fabric is water permeable so it sheds some rain but is not fully waterproof; it is designed to reduce sun and heat while allowing airflow and some water passage.

How durable is the sail?
Built from 200 GSM HDPE with reinforced edges, double stitching and stainless D-rings, it is intended for long-term outdoor use and comes with a 3 year assurance.
