ColourTree Custom Size 5 ft x 18 ft Blue Rectangle Sun Shade Sail

In this review of the ColourTree custom size 5 ft x 18 ft blue rectangle sun shade sail, the bottom line is simple: it is for homeowners and small-business owners who need a heavy-duty, waterproof shade that also blocks UV. The reviewer found the sail well suited to patios, carports, and play areas where durable fabric and secure corners matter most. Its standout trait is the combination of a dense 220 GSM virgin polyethylene weave with a waterproof coating, which delivers reliable shade, strong water resistance, and a cooled surface beneath the canopy.

Key Features

• 220 GSM virgin fabric: The dense, non-recycled polyethylene offers a thick, durable surface that resists tearing under tension and regular outdoor use.
• Waterproof coating: A waterproof layer prevents water from passing through, so the sail can shelter a patio or carport in light to moderate rain while still providing sun protection.
• UPF50 sun protection: The fabric blocks up to 95% of UV rays, helping keep surfaces and people underneath cooler and protected from sun damage.
• 316 stainless steel D-rings: Premium grade D-rings at each corner make attachment secure and simplify installation when anchoring to posts or hooks.
• Double reinforced stitching: All edges are finished with double-stitched seams to reduce fraying and strengthen the panels where D-rings bear load.
• 3 year limited warranty: The included warranty offers free replacement if the product fails within the limited warranty terms, which adds post-purchase reassurance.

Who It's For

The sail is ideal for homeowners with a small to medium patio, carport, or yard who want a robust, waterproof shade that also blocks UV. It fits well where a rectangular coverage of about 5 ft by 18 ft is useful, such as narrow walkways, over seating areas, or to extend carport coverage.

It is also a sensible choice for renters and DIYers who value straightforward installation using the supplied stainless D-rings and who prefer a fabric made from virgin material rather than recycled scrims. Those seeking decorative, delicate, or extremely lightweight summer-only sails should look elsewhere, because this product emphasizes durability and weather resistance over sheer lightness or ornamental trim.

Pros & Cons

Pros

• Excellent water resistance thanks to the waterproof coating, keeping areas dry in rain.
• Solid build quality from 220 GSM virgin polyethylene and double-stitched edges improves longevity.
• Easy and secure mounting with premium 316 stainless steel D-rings at each corner.
• Strong UV blocking (95% UV block) helps cool underlying surfaces and protect people.

Cons

• The rectangular 5 ft x 18 ft size is specific and may not suit larger open areas without additional sails or supports.
• Heavier, more durable fabric can be less flexible to fold and store compared with thinner summer sails.
