Custom Size 13 ft x 20 ft x 23.9 ft Waterproof Triangle Sun Shade Sail

Our review of this custom-size triangle sun shade sail finds it best suited to homeowners who need a robust, water-resistant canopy for patios, carports or yards. The single biggest reason to buy is the combination of a PU waterproof coating and strong corner reinforcement, which together deliver reliable rain protection and long-term tension under wind. It is a practical, low-maintenance canopy for people who want fast installation and meaningful temperature reduction without a permanent structure.

Key Features

• Waterproof material: Polyester with a PU waterproof coating keeps rain and wind from passing through, making it usable as a temporary shelter during showers.
• UV blockage: Blocks up to 90% of harmful UV, helping protect skin and outdoor furniture during peak sun hours.
• Temperature reduction: Lowers the temperature by up to 15 degrees under the shade, improving comfort on hot days.
• Reinforced edges and corners: Dual-layer white webbing and curved edges with stainless steel D rings give the sail strength where it sees the most tension.
• Quick setup: Designed to be taken down or pulled up in about 5 minutes, which suits seasonal use or temporary shade needs.
• Warranty: Comes with a 3 year limited warranty for added peace of mind.

Who It's For

This shade sail is ideal for homeowners and renters who need a portable, heavy-duty canopy over a patio, carport, or garden seating area and who value water resistance as well as UV protection. It works well for people in sunny and variable-weather regions who want a non-permanent, economical canopy alternative.

Those who should look elsewhere include buyers who need exact measured fit guidance for complex mounting geometry or those who want a fabric that is highly breathable rather than waterproof; some users prefer open-weave sails specifically for airflow rather than maximum water blocking.

Pros & Cons

Pros

• Strong waterproof coating provides real rain protection rather than only sun shading.
• Reinforced edges and stainless steel D rings make it durable under tension and wind.
• Blocks a large portion of UV, improving comfort and protecting items beneath it.
• Easy to take down or put up, making seasonal or temporary use convenient.

Cons

• Size perception varies; some customers find the fit smaller than they expected for their space.
• Because it is waterproof, it sacrifices some airflow compared with open-weave shade sails.
