Custom Size 11ft x 16ft x 19.4ft Red Right Triangle Sun Shade Sail

Our review of this custom right triangle sun shade sail finds it best for homeowners and small commercial spaces that need a tailored sun-protection solution. The single biggest reason to buy is its combination of heavy-duty 200 GSM HDPE fabric and 95% UV blockage, which delivers reliable sun protection while still letting air and water pass through. Installers who want a measured fit will appreciate the D-ring to D-ring sizing method and stainless steel hardware, while shoppers expecting rigid waterproofing or an off-the-shelf size may need to check measurements carefully.

Key Features

• 95% UV protection: The 200 GSM HDPE material blocks up to 95% of harmful UV rays for safer outdoor time in sun-exposed areas.
• Temperature reduction: The shade sail can reduce surface and air temperature by up to 15 degrees compared with unshaded areas, improving comfort under the canopy.
• Custom sizing: Made to order using D-ring to D-ring measurements so the sail fits irregular spaces and can be tailored with straight-edge requests.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity for seasonal and commercial use.
• Breathable and weather tolerant: The fabric is water and air permeable, shedding wind loads while allowing drainage and airflow.
• Installation flexibility: Can be mounted to trees, roofs, walls or poles using standard mounting hardware kits and leave small corner gaps for tensioning.

Who It's For

This shade sail suits homeowners, small cafes, play areas and hobby farmers who need a durable, custom-sized canopy to reduce sun exposure and heat. It is particularly useful where a tailored fit is important, such as over patios, chicken runs, or oddly shaped outdoor seating where factory sizes do not work.

Shoppers who want a fully waterproof awning or a rigid, tensioned shade with no airflow should look elsewhere, since the fabric is intentionally water and air permeable. Also, buyers who prefer off-the-shelf, very large single-piece sails should confirm size expectations before ordering.

Pros & Cons

Cons

Our Verdict

This custom right triangle shade sail is a practical, cost-effective choice for anyone needing tailored sun protection and temperature reduction.

How durable is the hardware?
The sail uses stainless steel D-rings and reinforced edges with double-layer stitching for added durability and a 3 year assurance.
