ShadeMart 17 ft x 22 ft Brown Sun Shade Sail UPF50 Rectangle - Durable

In this review the ShadeMart 17' x 22' Brown Sun Shade Sail is evaluated for homeowners and outdoor owners who need a large, breathable canopy that blocks sun and lowers temperatures. The sail's biggest draw is its woven HDPE fabric that is water permeable and blocks up to 95% of harmful UV rays, so this is ideal for patios, carports, pergolas and RV cover needs where airflow and sun protection matter more than full waterproofing.

Key Features

• Woven HDPE fabric: The high density polyethylene weave provides durable UV protection while remaining breathable so air circulates beneath the canopy.
• UPF50 sun blocking: Blocks up to 95% of harmful UV rays, reducing surface temperatures below the sail and protecting people and vehicles from sun damage.
• Stainless steel corner D rings: Heavy duty stainless D rings attached to reinforced white webbing give secure anchor points for a reliable installation.
• Water and air permeable: The style allows water and wind to pass through, preventing pooling and reducing wind stress on the fabric in gusty conditions.
• Custom sizing available: ShadeMart offers custom sizes to fit unusual spaces, with the vendor asking buyers to measure their venue carefully before ordering.
• Rectangle styling: A simple rectangular shape integrates easily with existing outdoor designs and can be used alone or in multiples for larger coverage.

Who It's For

This shade sail is aimed at homeowners, RV owners, and small businesses wanting a breathable, UV-blocking canopy for patios, carports, pool areas and pergolas where airflow and sun protection are priorities. It works well where water drainage is needed rather than complete waterproof coverage.

It is less suitable for buyers who need a fully waterproof shelter or those who expect exact color matching from images; some customers reported mixed reactions to color tones and manual measurement tolerances, so precise color-critical or waterproof applications should consider alternative products.

Pros & Cons

Pros

• Effective sun protection that blocks most UV and noticeably lowers temperature under the sail.
• Breathable, water permeable design prevents pooling and improves comfort on hot days.
• Sturdy construction with stainless steel D rings and reinforced webbing supports secure attachment and durability.
• Custom size options make it adaptable for a variety of installation areas.

Cons

• Not waterproof, so it will not keep rain out of an area during heavy storms.
• Color and stated size may vary slightly due to manufacturing and manual measurements.
