ShadeMart 8 ft x 17 ft Green Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 8' x 17' green rectangle sun shade sail, the bottom line is simple: it is a straightforward, heavy-duty fabric canopy for people who need reliable sun protection and airflow over a large outdoor area. Our review found the sail excels at reducing heat and blocking UV while remaining breathable, making it a good choice for patios, carports, and poolside coverage where water runoff through the fabric is acceptable. Installation is approachable with the right hardware, and the material and stainless corner rings feel built to last.

Key Features

• MATERIAL: Woven HDPE fabric provides a durable, tear-resistant surface that withstands regular outdoor use and resists UV degradation.
• UV PROTECTION: The shade blocks up to 95% of harmful UV rays (UPF50) which noticeably lowers temperatures beneath the canopy.
• BREATHE & DRAIN: Water permeable construction lets rain pass through, avoiding pooling and reducing wind load on the sail.
• HARDWARE READY: Stainless steel D-rings attached to heavy duty webbing give secure anchor points compatible with common shade hardware kits.
• CUSTOM SIZE OPTIONS: Available in multiple sizes so you can order dimensions closer to your mounting points for a cleaner fit.
• STYLING: Rectangle shape and color options allow the sail to blend with landscaping or add a decorative element to a patio or carport.

Who It's For

This shade sail is aimed at homeowners and renters who want an affordable, durable canopy to reduce heat and sun exposure over patios, pergolas, pools, and carports. It suits people who prefer a breathable fabric that will not trap water after rain and who plan to mount the sail to posts, walls, or trees using a separate hardware kit.

It is less suitable for anyone who needs a waterproof canopy or a perfectly dimensioned architectural sail without any variation from manual measurements; if you require full rain protection or factory-seamed waterproof panels, consider a waterproof awning instead.

Pros & Cons

Our Verdict

The ShadeMart 8' x 17' rectangle shade sail is a practical choice for anyone needing solid sun protection, breathability, and durable attachment points at an affordable price. It delivers significant UV blocking and cooler shade for patios, pools, and carports, but buyers should plan hardware and accept that the fabric is not waterproof and that manual sizing may vary. Overall it offers good value where airflow and UV protection are priorities.

Frequently Asked Questions

Is the shade sail waterproof?
No. This model is water permeable and breathable, so it will not keep an area dry in rain.

What hardware do I need to install it?
Stainless steel D-rings are provided on the corners, but you will need an appropriate shade sail hardware kit (turnbuckles, pad eyes or poles, and mounting anchors) sold separately for secure installation.

Will it reduce temperature under the sail?
Yes. The woven HDPE fabric and UPF50 rating block a large portion of sunlight and typically lowers perceived temperature under the canopy by several degrees.
