Right Triangle 12ft x 12ft x 17ft Sun Shade Sail - Heavy Duty UPF50

In this review we look at the ColourTree right triangle sun shade sail sized 12 ft x 12 ft x 17 ft and whether it delivers on durability and sun protection. The bottom line: this sail is for anyone who needs a heavy duty, long-lasting shade solution that blocks sun effectively. The standout reason to buy is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the manufacturer says was lab-tested for extended UV exposure and is far more durable than recycled alternatives.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled material provides a sturdier feel and is designed to resist tearing and premature wear compared to recycled fabrics.
• UV stabilized compound: Fabric treatment prevents drying, fading and brittleness so the sail stays serviceable longer in strong sunlight.
• 95% UV blockage: Blocks most harmful ultraviolet rays and helps reduce temperature in shaded areas for patios, pools and carports.
• Breathable woven fabric: Allows air and water to pass through to avoid pooling during rain while still providing effective shade.
• Reinforced edges and stainless rings: Double layered stitched seams and D-rings at corners improve strength and simplify mounting when paired with proper hardware.
• Three year warranty: Limited warranty under normal conditions gives reasonable assurance for typical residential use.

Who It's For

This sail suits homeowners and small commercial users who need a durable shade for patios, balconies, swimming pools or carports and who prefer a breathable mesh that reduces heat but does not trap water. It is especially good for installations where sun exposure is intense and material longevity matters.

Those who should look elsewhere include buyers wanting a fully waterproof canopy or a sail with included hardware; this product requires separate installation kits and cables. Also, if exact custom-fit measurements or ultra-lightweight portability are top priorities, a different product may be more appropriate.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE fabric that feels substantial and resists UV damage.
• Effective UV protection that blocks 95% of harmful rays and helps cool shaded areas.
• Breathable design prevents water pooling and performs well in wet weather.
• Strong reinforced seams and stainless steel D-rings make installation secure when paired with proper hardware.

Cons

• Installation hardware is sold separately, so additional purchase and proper cable selection are required.
• Not fully waterproof, so it will not provide complete rain shelter like a coated canopy would.
