12ft x 17ft x 20.8ft Green Right Triangle Sun Shade Sail - UPF50 Heavy

In this review the 12ft x 17ft x 20.8ft green right triangle sun shade sail is evaluated for homeowners and small-business owners who need reliable UV protection and a durable, breathable canopy. The bottom line: this is a heavy-duty, commercially constructed shade sail made from 190 GSM 100% virgin HDPE that blocks up to 95% of UV while remaining breathable and resistant to fading, making it a practical long-term choice for patios, pools, and carports.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled fabric gives greater durability under sun exposure compared to recycled alternatives, reducing tearing and premature wear.
• UV stabilized compound: Material treated to resist drying out and fading after prolonged sunlight exposure, extending the useful life of the sail.
• 95% UV blockage: Blocks most harmful UV radiation and lowers local temperature in shaded areas for more comfortable outdoor use.
• Breathable woven construction: Allows air and water to pass through so rainwater will not pool and the area stays ventilated.
• Reinforced edges and D-rings: Double-layer stitched seams and stainless steel D-rings provide secure anchor points and resist fraying.
• 3 year limited warranty: Coverage under normal weather and usage provides added confidence in the product's longevity.

Who It's For

People with medium to large outdoor spaces who need a robust, permanent-looking shade solution will appreciate this right triangle sail; its commercial-grade 190 GSM virgin HDPE fabric is appropriate for patios, swimming pools, balconies, and carports where sun exposure is high. Owners who prioritize UV protection and a breathable canopy that prevents water pooling will find the material and weave especially useful.

Those who need a temporary, ultra-lightweight sail or want a fully waterproof canopy should look elsewhere, as this product is designed to be breathable rather than water-impermeable. Also, installation hardware is not included, so buyers without existing posts, walls, or proper shade-sail fittings should plan to purchase compatible hardware separately.
