ShadeMart 9 ft x 17 ft Blue Waterproof Shade Sail Rectangle - Cool

In this review the ShadeMart 9 ft x 17 ft Blue Waterproof Shade Sail is presented as a practical canopy for patios, carports and backyards where strong sun protection and basic rain resistance are needed. The single biggest reason to buy is its combination of 95% UV blockage and sturdy construction that noticeably cools a covered area; reviewers consistently noted reduced surface temperatures and a well-made fabric. Installation requires attention to tension to avoid sagging, but when mounted correctly this sail offers reliable shade and value for the price.

Key Features

• Waterproof coating: Polyester fabric with a PU waterproof layer helps resist light rain while keeping the covered area dry in short showers.
• High UV protection: The sail blocks up to 95% of harmful UV, which reduces surface temperatures by up to about 15 degrees compared with no shade.
• Reinforced edges: Curved edges with dual-layer white webbing improve durability and help the sail hold shape under tension.
• Stainless steel corners: D rings at each corner are secured to the dual webbing for reliable anchoring to a mounting kit.
• Custom sizing available: ShadeMart offers customized sizes that usually ship in about two business days for tailored coverage.
• Simple maintenance: The fabric is compact and easy to remove for storage or seasonal changes.

Who It's For

This shade sail is best for homeowners who need an affordable, effective canopy for a patio or carport where sunlight is the main concern and only occasional light rain is expected. It is well suited to DIY installers who can ensure firm anchor points and maintain outward tension to prevent pooling.

Those who require full waterproofing in heavy storms, large commercial installations, or exact color matching should look elsewhere; the sail withstands light rain but can collect water if sagging occurs, and color accuracy has mixed feedback from buyers.

Pros & Cons

Pros

• Good build quality with strong stitching and reinforced corner loops that hold up under tension.
• Effective shade and temperature reduction on patios and outdoor seating areas.
• Compact, easy to install or remove when paired with an appropriate hardware kit.
• Custom sizes available with quick turnaround for tailored coverage.

Cons

• Not fully stormproof; water can accumulate if the sail is not installed with maximum tension or during heavy rain.
• Some customers reported size and color variation compared with expectations, so measure carefully and expect slight differences.
