17ft x 20ft x 26.2ft Red Right Triangle Sun Shade Sail - UPF50

In this review of the 17' x 20' x 26.2' red right triangle sun shade sail, the bottom line is simple: it suits homeowners and small commercial spaces that need a large, customizable shade solution with strong UV protection. The reviewer found the sail's single biggest advantage to be its 95% sun protection from 200 GSM HDPE fabric, which reliably reduces direct UV exposure while lowering surface temperatures by up to 15 degrees compared with unshaded areas. Installation takes some planning but is flexible once measurements are taken.

Key Features

• 95% UV blockage: The 200 GSM HDPE material blocks up to 95% of harmful rays to create a safer outdoor space.
• Temperature reduction: The sail lowers ambient temperatures by as much as 15 degrees versus unshaded spots, improving comfort under the canopy.
• Custom sizing: Measurements are taken D-ring to D-ring so the sail can be tailored to fit irregular spaces and alternative edge requests are available.
• Durable build: Reinforced edges, double-layer stitching and stainless steel D-rings contribute to a stronger long-term installation.
• Permeable design: The fabric is water and air permeable to reduce wind load and allow rain to pass through rather than pooling.
• Easy mounting guidance: The product includes clear guidance on corner gaps and compatible mounting to trees, walls or poles for flexible placement.

Who It's For

This shade sail is best for homeowners, patio owners, small cafes or playgrounds that need a large triangular canopy with strong UV protection and a custom fit. It is also a good match for those who prefer a fabric that breathes and reduces heat rather than fully waterproof tarps.

Those who should look elsewhere are buyers wanting a fully waterproof awning or users unwilling to plan corner gaps and measure D-ring to D-ring precisely; also people expecting an identical lifespan in extremely harsh sun without occasional replacement should consider heavier commercial-grade alternatives.

Pros & Cons

Pros

• Provides substantial sun protection with 95% UV blockage for safer outdoor use.
• Noticeable cooling effect, reducing temperatures by up to 15 degrees in shaded areas.
• Sturdy construction with stainless D-rings and reinforced, double-stitched edges.
• Custom sizing and flexible mounting options make it adaptable to varied layouts.

Cons

• Durability reports are mixed; some users experienced degradation after about a year to 18 months in strong sun.
• Not fully waterproof-fabric is water permeable so it will not create a dry sheltered area in heavy rain.

Our Verdict

The 17' x 20' x 26.2' red right triangle shade sail is a practical, good-value option for patios, playgrounds and commercial outdoor seating that need strong UV protection and cooler shaded areas. Its custom sizing and durable hardware make it versatile, though buyers should expect fabric to age over time in intense sun and not rely on it as a waterproof shelter.

Frequently Asked Questions

Is this sail waterproof?
The fabric is water and air permeable, so it is not fully waterproof and will allow light rain to pass through.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each side; the manufacturer recommends leaving at least 0.5 ft gap at corners to poles or reducing by 1 to 1.5 ft per side when needed.

How long does the sail last in sun?
Longevity varies by exposure; many users report over a year of service, but some have seen significant wear after about 14 months in very strong sunlight.
