ColourTree 17ft x 21ft Turquoise Sun Shade Sail Canopy - Heavy Duty UV

In this review of the ColourTree 17' x 21' Turquoise Sun Shade Sail Canopy, the bottom line is simple: this heavy duty rectangle shade is for homeowners and businesses who want strong sun protection and long life from a fabric canopy. It stands out because it uses 190 GSM 100% virgin HDPE with UV stabilized compound, which the brand says withstands long sun exposure and blocks 95% of harmful UV. For people who need a breathable, water-permeable canopy over patios, pools or carports, the sail delivers practical shade without trapping heat.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric intended to resist tearing and degradation under prolonged sun exposure for longer service life.
• UV stabilized compound: Material treated to reduce drying, fading and brittleness so the canopy keeps shape and color after long UV exposure.
• 95% UV blockage: Fabric construction blocks the majority of harmful UV rays and lowers direct sunlight in shaded areas for cooler outdoor use.
• Breathable woven fabric: Allows air and rainwater to pass through, preventing pooling and reducing wind sail effect compared with solid tarps.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy corner stitching provide stronger attachment points for cables and hardware.
• 3 year limited warranty: Coverage against defects under normal weather and usage gives buyers a baseline of confidence.

Who It's For

This shade sail is best for homeowners, small businesses and property managers who need a durable, breathable canopy for patios, decks, swimming pools, balconies and carports. The heavy 190 GSM virgin HDPE and UV stabilization make it suited to high-sun climates where longevity and color retention matter.

It is less suitable for buyers who expect a completely waterproof shelter or a lightweight, temporary cover; the woven fabric is intentionally permeable so water and air pass through, and professional-grade hardware is required (sold separately) to get a secure installation.

Pros & Cons

Pros

• Strong UV protection and heat reduction thanks to 95% blockage and dense 190 GSM fabric.
• Durability focus with virgin HDPE and UV stabilized compound reduces fading and brittling over time.
• Breathable fabric prevents water pooling and allows airflow for comfort in shaded areas.
• Reinforced seams and stainless steel D-rings simplify secure attachment when used with recommended hardware.

Cons

• Requires separate hardware kits and proper cables for installation, which adds cost and effort.
• Some users report mixed durability in extreme wind conditions, so heavy wind anchoring and inspection are advised.
