13 ft x 18 ft x 22.2 ft Red Right Triangle Sun Shade Sail - Durable UV

In this review the 13' x 18' x 22.2' Red Right Triangle Sun Shade Sail is assessed for homeowners and outdoor space owners who need a large, angled canopy that blocks sun and reduces heat. The single biggest reason to buy is its material and shape design: a virgin polyethylene fabric with curved edges that resists sagging and delivers up to 95% UV blockage, making it a practical shade solution for patios, pools, carports and yards.

Key Features

• Corner-to-corner measurement: The sail is cut and measured from corner to corner so buyers can match the triangular span to existing posts or anchor points.
• Curved edge design: Edges are made slightly curved with a calculated radian to prevent sagging and maintain a cleaner, taut appearance over time.
• High UV protection: The virgin polyethylene fabric provides up to 95% UV blockage and about 90% visibility reduction for cooler, safer outdoor use.
• Lightweight and strong: The polyethylene material balances strong tensile strength with low weight so it is easier to handle during installation and removal.
• Seasonal weather performance: The fabric shades and cools in summer, offers anti-frost properties overnight and is slightly rainproof during light showers.
• Customizable and warranted: The product can be customized to fit unusual layouts and is backed by a 3-Year Limited Warranty for added confidence.

Who It's For

This shade sail is best for homeowners with a backyard, patio, pool area, driveway or carport who need an attractive, large triangular canopy to reduce sun exposure and heat. It works well for people who want a durable, low-weight fabric that stays relatively taut thanks to its curved edge design.

Those who should look elsewhere include buyers seeking a fully waterproof awning for heavy rain or insulated structures for cold climates; the sail is only slightly rainproof and is intended primarily for shade, cooling and light weather protection rather than full waterproofing.

Pros & Cons

Pros

• Provides strong UV protection and notable cooling benefits for outdoor living areas.
• Curved edges and corner-to-corner sizing reduce midspan sag and improve appearance.
• Lightweight virgin polyethylene is durable and easy to handle during installation.
• Custom order options and a 3-Year Limited Warranty add flexibility and peace of mind.

Cons

• Not fully waterproof, so it is not a replacement for solid or fully sealed awnings in heavy rain.
• Included hardware receives mixed feedback, so additional or upgraded fittings may be preferred for some installations.

Specifications
