11 ft x 11 ft x 15.6 ft White Right Triangle Sun Shade Sail - UV Block

In this review we look at the 11 ft x 11 ft x 15.6 ft white right triangle sun shade sail from SHADESPEARE to decide who should buy it and why. The bottom line: this shade sail is best for homeowners and renters who want a lightweight, durable canopy that blocks most UV while improving outdoor comfort. The single biggest reason to buy is its material and cut - virgin polyethylene fabric with a slightly curved edge prevents sagging and delivers up to 95% UV blockage and substantial cooling in summer.

Key Features

• Measurement method: Size is measured corner to corner so buyers know the installed span and can plan mounting points accurately.
• Curved edge design: Precisely calculated radian curves on the edges prevent the sail from sagging in the middle for a neater look and better water run-off.
• Material: Made from virgin polyethylene, the fabric balances strong tensile strength with low weight for easier handling and longer life.
• UV and visibility reduction: Provides up to 95% UV blockage and about 90% visibility reduction to keep outdoor areas cooler and protect surfaces.
• Seasonal versatility: Offers shading and ventilation in summer, reduces frost exposure at night, and is slightly rainproof during light showers.
• Custom orders and warranty: Available for customization and backed by a 3-year limited warranty for added reassurance.

Who It's For

This shade sail is ideal for homeowners with patios, pools, driveways, carports, or gardens who want a clean white canopy that reduces heat and sun exposure. It suits people who need a triangular right-angle cover that can be anchored between trees, posts, or buildings and who value a fabric that resists sagging and delivers strong UV protection.

Those looking for a fully waterproof awning, motorized adjustment, or rigid-frame structure should look elsewhere; this product is a fabric sail designed for breathability and sun blocking rather than heavy rain protection or permanent enclosure.

Pros & Cons

Pros

• High UV protection and good visibility reduction make outdoor areas noticeably cooler and more comfortable.
• Curved edges and measured corner-to-corner sizing reduce mid-span sag and improve the finished appearance.

• Custom orders available and a 3-year limited warranty add flexibility and peace of mind.

Cons

• Hardware included receives mixed feedback from customers, so buyers may need to upgrade fittings for some mounting situations.
• Not fully waterproof; it is only slightly rainproof during light showers and not meant as a replacement for a solid roof.
