Custom Size 11ft x 16ft x 19.4ft Right Triangle Sun Shade Sail - UPF50

In this review the reviewer looks at the custom size 11' x 16' x 19.4' right triangle sun shade sail and finds it best suited for homeowners and small commercial spaces seeking reliably cooler, UV-safe outdoor coverage. The single biggest reason to buy is its effective sun protection: made from 200 GSM HDPE that blocks up to 95% of UV rays while remaining water and air permeable, it reduces surface temperatures and stands up to regular outdoor use. Installation is flexible enough for trees, walls or poles, and the seller offers custom tailoring for a precise D-ring to D-ring fit.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays so patio and play areas stay safer in full sun.
• Temperature reduction: The sail cuts ambient surface heat by up to 15 degrees compared with unshaded spots for a noticeably cooler sitting area.
• Water and air permeable: The open weave sheds some water and allows airflow, reducing wind load and pooling during light rain.
• Reinforced construction: Stainless steel D-rings, reinforced edges and double-layer stitching increase durability and resist fraying over time.
• Custom sizing: The shade is made to measure from D-ring to D-ring so you can get a tailored fit for odd or tight spaces.
• Commercial standard: Built to a higher durability standard with a 3 year assurance for longer term outdoor use.

Who It's For

This shade sail is aimed at homeowners, small businesses and hobbyists who need a custom-sized triangular sail to cover patios, play yards, chicken runs or outdoor seating. It particularly suits projects where good UV protection and airflow are priorities and where standard off-the-shelf sizes do not fit the intended anchor points.

Those who should look elsewhere include buyers needing a fully waterproof canopy or rigid structure for heavy storms, or anyone who prefers permanent hardtop shading; this product is a breathable, fabric sail designed for sun protection and light weather but not to replace a solid roof.

Pros & Cons

Pros

• High sun blockage from 200 GSM HDPE gives dependable UV protection for outdoor spaces.
• Custom sizing and reinforced D-rings make it straightforward to get a precise fit and solid attachments.
• Fabric construction reduces temperature and provides airflow to limit heat buildup beneath the sail.
• Durable stitching and stainless hardware promise longer service backed by a 3 year assurance.

Cons

• Some customers note the sail appears smaller than expected, so careful D-ring to D-ring measurement is essential.
• Not fully waterproof; it is air and water permeable, so heavy rain will pass through rather than form a dry shelter.
