ColourTree Custom Size 12ft x 20ft x 23.3ft Black Right Triangle Sun

In this review of the ColourTree custom size 12' x 20' x 23.3' black right triangle sun shade sail, the bottom line is clear: this is a heavy duty option for anyone who needs high UV protection and a long-lasting woven fabric for patios, pools, or carports. The reviewer found the single biggest reason to buy is the use of 190 GSM 100% virgin HDPE treated with UV stabilized compound, which promises superior resistance to fading and tearing compared with recycled materials while still remaining breathable.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric is designed to offer greater durability under sun exposure than recycled alternatives.
• UV stabilized compound: The material is treated to resist drying out and fading, which helps extend usable life in sunny installations.
• 95% UV blockage: The woven fabric significantly reduces temperature and harmful UV radiation in shaded areas, improving comfort for patios and pools.
• Breathable, water-permeable weave: Air and rainwater pass through the fabric to prevent pooling and reduce wind load, lowering maintenance needs.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy corner stitching secure the D-rings for reliable attachment points.
• Three year limited warranty: The product includes a warranty under normal weather and usage, giving buyers some protection against early defects.

Who It's For

This shade sail suits homeowners and small commercial users who need a large, high-coverage shade for decks, above-ground pools, carports or outdoor seating areas and who value durability over the lowest possible price. The heavy 190 GSM virgin HDPE fabric is appropriate where long-term UV stability is important.

Those who should look elsewhere include buyers who require a flexible hardware-included turnkey kit or very precise prefitted sizes; installation hardware is sold separately and each D-ring needs its own cable rope. If you need an inexpensive short-term solution, a lighter recycled fabric sail will be cheaper up front.
