Custom Size 11ft x 20ft x 22.8ft Right Triangle Sun Shade Sail

In this review of the Custom Size 11' x 20' x 22.8' right triangle sun shade sail, the bottom line is simple: this is a practical, heavy-duty sun canopy for people who need tailored coverage and strong UV protection. The reviewer found it best for homeowners and small commercial spaces who want a durable, custom-fit solution that cuts sun and heat, while offering easy installation options. The single biggest reason to buy is the fabric and construction-200 GSM HDPE with reinforced edges and stainless D-rings-that delivers reliable 95% sun protection and long-term performance.

Key Features

• 95% UV blockage: The knitted 200 GSM HDPE fabric blocks up to 95% of harmful rays for safer outdoor time.
• Temperature reduction: The shade reduces ambient temperature by as much as 15 degrees compared with fully exposed areas to make patios and play areas more comfortable.
• Custom sizing: Delivered to the exact D-ring to D-ring measurement so the sail fits a specific area instead of forcing standard sizes.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings resist fraying and handle wind without early failure.
• Water and air permeable: The breathable knit reduces wind load and lets moisture pass, preventing water pooling while providing shade.
• Easy installation guidance: Clear suggestions about corner gaps and mounting points make it straightforward to attach to trees, walls or poles.

Who It's For

This shade sail is a good pick for homeowners, landscapers or small business owners who need a custom-fit canopy for patios, playgrounds, carports or outdoor dining areas. It suits anyone who values durability and UV protection over a cheap off-the-shelf square and wants a tailored right-triangle shape to match a tricky space.

If you need an instant pop-up or a fully waterproof tarp for heavy rain protection, look elsewhere; this sail is water-permeable and designed primarily for sun protection and breathability rather than complete rainproof coverage. Also, buyers who expect exact factory trim to the inch should carefully measure D-ring to D-ring and accept the need for a small installation gap as recommended.

Pros & Cons

Pros

• Very effective at blocking sun and reducing temperature thanks to heavy 200 GSM HDPE fabric.
• Sturdy build with reinforced edges and stainless D-rings gives confidence in wind and sun exposure.
• Custom measurement option means a much better fit for irregular outdoor spaces.
• Breathable construction prevents water pooling and reduces wind stress on mounts.

Cons

• Not fully waterproof; it is water permeable by design and is intended primarily for shade rather than full rain protection.
• Some buyers may find the delivered size smaller than expected if measurements are not exact, so careful D-ring to D-ring measuring is essential.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring along the edges where the sail will be mounted; allow the recommended corner gap of at least 0.5 ft or reduce side lengths by 1 to 1.5 ft as advised for best fit.

Is this sail waterproof?
No, it is water and air permeable by design; it sheds some rain but is intended primarily for shade and breathability rather than full waterproofing.

How durable are the attachment points?
Attachment points are stainless steel D-rings with reinforced edges and double-layer stitching, designed to withstand sun and wind typical of patio and commercial use.
