Custom Size Right Triangle Sun Shade Sail 11ft x 15ft x 18.6ft - UPF50

Our review of this custom size right triangle sun shade sail finds it best suited for homeowners and small commercial spaces that need reliable sun protection and a tailored fit. The single biggest reason to buy is the material performance: the 200 GSM HDPE fabric blocks up to 95% of UV rays while remaining breathable and water permeable, so it cools an area without trapping moisture. Installation is straightforward for anyone comfortable with basic mounting hardware, and the option to order to measure makes it a practical choice for odd-shaped areas.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks most harmful sun rays, providing safer shade for people, pets, and outdoor living spaces.
• Temperature reduction: The sail can lower ambient temperature by about 15 degrees versus unshaded spots, making patios and play areas more comfortable.
• Water and air permeable: The breathable weave sheds some water and allows airflow, reducing heat buildup and wind resistance.
• Custom sizing: The product is made to order using D-ring to D-ring measurements so the sail fits irregular layouts better than fixed sizes.
• Commercial-grade durability: Reinforced edges, stainless steel D-rings, and double-layer stitching resist fraying and extend service life, backed by a 3 year assurance.
• Flexible installation: It mounts to trees, walls, roofs, or poles and advises specific D-ring clearances for best tensioning and stability.

Who It's For

This shade sail works well for homeowners who need a precise fit over decks, patios, poolside areas, or chicken runs and want strong UV protection without a solid canopy. Small commercial users who need durable, breathable shade for outdoor seating or vendor areas will also benefit from the commercial-standard construction and stainless hardware.

Shoppers who prefer ready-made kits with fixed dimensions or who need full waterproof coverage should look elsewhere; this sail is water permeable rather than fully waterproof, and customers should follow the sizing guidance carefully to avoid a too-small result.

Pros & Cons

Pros

• High UV blockage from the 200 GSM HDPE fabric provides trustworthy sun protection.
• Noticeable temperature drop under the sail improves outdoor comfort during heat.
• Durable construction with stainless D-rings and reinforced stitching for long-term use.
• Custom order option gives a tailored fit for awkward or irregular spaces.

Cons

• Size must be measured carefully; customers reported receiving sails that felt extremely small relative to expectations.
• Permeable fabric reduces but does not completely stop water, so it is not a full rainproof canopy.
