ColourTree Custom Size 13ft x 17ft x 21.4ft Black Right Triangle Sun

In this review the ColourTree custom size 13' x 17' x 21.4' right triangle sun shade sail is judged on durability and sun protection for residential and light commercial use. The bottom line: it is best for homeowners or pool owners who want a heavy duty, breathable shade that blocks most UV and stands up to regular sun exposure; the single biggest reason to buy is the fabric, which is 190 GSM 100% virgin HDPE treated with a UV stabilized compound for extended lifespan under sunlight.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled material provides a denser weave that feels sturdier and resists tearing better than common lighter fabrics.
• UV stabilized compound: Factory treatment reduces fading and drying so the sail maintains strength and color after prolonged sun exposure.
• 95% UV blockage: The woven fabric substantially lowers sunlight and heat beneath the sail, making it practical for patios, pools and carports.
• Breathable design: The weave allows air and water to pass through so rain does not pool and ventilation reduces heat buildup beneath the canopy.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings create strong anchor points to distribute load and reduce fraying.
• 3 year limited warranty: Manufacturer support covers defects under normal use, offering added confidence for long term outdoor installation.

Who It's For

The sail is ideal for homeowners with a patio, balcony or above-ground pool who want reliable shade and reduced UV exposure, and for small commercial spaces needing a heavy duty, breathable canopy. The robust 190 GSM fabric and reinforced corners suit installations where the sail will be mounted for months at a time in sunny climates.

Those who should look elsewhere include people needing an exact off-the-shelf size other than this custom 13' x 17' x 21.4' triangle, or buyers who prefer fully waterproof tarpaulin-style covers rather than a breathable mesh. Also plan to buy proper hardware separately, as the sail is sold without mounting kits.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE feels substantial and resists quick degradation in sun.
• Fabric blocks up to 95% of UV, noticeably lowering sunlight and temperature underneath.
• Breathable weave prevents water pooling and improves airflow compared with solid covers.
• Reinforced seams and stainless steel D-rings make mounting more secure when paired with proper hardware.

Cons

• Sold without installation hardware, so buyers must purchase suitable cables or kits separately for correct anchoring.
• Some users report mixed long-term durability in very windy conditions, so heavy storm protection is advisable.

Frequently Asked Questions

Does this sail include mounting hardware?
No. The sail is sold without hardware; each stainless steel D-ring requires a cable or rope and proper wall or pole anchors sold separately.

How much UV protection does the fabric provide?
The woven 190 GSM virgin HDPE fabric is rated to block up to 95% of harmful UV rays, reducing sunlight and temperature under the sail.

Is the fabric waterproof?
No. The breathable mesh allows water to pass through to avoid pooling, so it reduces sun and heat but is not a waterproof tarpaulin.
