11ft x 17ft x 20.2ft Right Triangle Sun Shade Sail - Heavy Duty UPF50

In this review the focus is on a heavy duty right triangle sun shade sail made to order in a custom 11' x 17' x 20.2' size, aimed at homeowners and small commercial spaces that need reliable sun protection. The reviewer found the single biggest reason to buy is the fabric construction: a 190 GSM 100% virgin HDPE material treated with UV stabilized compound that survived extended sun exposure testing and blocks a large portion of UV, making it a practical choice for patios, pools and carports where durable, breathable shade matters.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric offers long-term durability and resists drying out, tearing and fading under intense sun exposure.
• UV Stabilized Compound: Laboratory-tested UV stabilization helps the fabric retain strength and color after extended outdoor exposure.
• 95% UV Blockage: The woven material significantly reduces harmful UV and lowers temperature in the shaded area for more comfortable outdoor use.
• Breathable Woven Fabric: Air and water pass through the mesh so rain does not pool and the sail remains effective without extra maintenance.
• Reinforced Edges and D-rings: Double layered stitched seams and stainless steel D-rings at corners provide secure attachment points and resist fraying.
• 3 Year Warranty: A limited warranty offers added confidence under normal weather and usage conditions.

Who It's For

This shade sail is well suited to homeowners, pool owners and small commercial operators who need a robust, long-lasting shade solution in custom sizes and appreciate a high UPF fabric. Its breathability makes it a good choice for locations that experience both sun and occasional rain, where water pooling would be a problem.

It is less appropriate for buyers who need an off-the-shelf fixed mounting kit included, since installation hardware is sold separately and the seller recommends particular cable and hardware types; also those wanting a completely rigid, waterproof canopy should look elsewhere.
