Custom Size 15ft x 17ft Blue Rectangle Sun Shade Sail - UPF50

Our review of the 15' x 17' blue rectangle sun shade sail finds it best suited for homeowners and small businesses who need reliable, customizable sun protection without a permanent structure. The single biggest reason to consider this sail is simple: it pairs heavy-duty 200 GSM HDPE fabric with reinforced hardware so it blocks up to 95% of harmful UV while remaining breathable and durable. Installation is straightforward for a handy DIYer, and the option to order custom sizes ensures a tailored fit for patios, play areas, or outdoor seating.

Key Features

• 95% UV blockage: The 200 GSM HDPE material is engineered to block up to 95% of UV rays, which reduces sun exposure for people and furniture underneath.
• Temperature reduction: The sail lowers ambient temperature by up to 15 degrees compared to unshaded areas, giving noticeably cooler shade on hot days.
• Heavy duty construction: Stainless steel D-rings, reinforced edges, and double-layer stitching improve longevity and resist fraying in high winds.
• Water and air permeable: The breathable weave sheds some rain while allowing airflow, reducing wind load and preventing a closed-in feel.
• Customizable fit: The product is made to order using D-ring to D-ring measurements so it can match irregular or exact spaces.
• Three-year assurance: The manufacturer includes a three-year assurance that covers material and construction concerns for normal use.

Who It's For

This shade sail works well for homeowners with patios, decks, or playgrounds who want a flexible sun solution that can be attached to walls, poles, or trees. It also fits small commercial spaces such as cafes or market stalls where a breathable, UV-blocking canopy is preferred over solid roofing.

It is not ideal for those seeking a fully waterproof canopy for heavy, sustained rain or for buyers who need a quick, temporary cover for one-off events; this sail is water permeable and intended as a sun-first solution. People without tools or experience in anchoring fabric under tension may prefer professional installation.

Pros & Cons

Pros

• High UV protection that blocks about 95% of sunlight for safer outdoor use.
• Durable build with stainless steel D-rings and reinforced, double-stitched edges to resist wear.
• Custom sizing allows a tailored fit for oddly shaped areas or exact D-ring spacing.
• Breathable material reduces temperature and wind pressure while still providing shade.

Cons

• Not fully waterproof, as the fabric is designed to be water and air permeable rather than water-tight.
• Proper measurement and gap allowances are required for best performance, which can be tricky for first-time installers.

Frequently Asked Questions

Can this sail be cut to exact dimensions?
Yes, the manufacturer customizes sails by D-ring to D-ring measurements so you can order a tailored size; contact them for straight-edge options.

Is the fabric waterproof?
No, the 200 GSM HDPE fabric is water and air permeable, designed to shed light rain but not to act as a fully waterproof canopy.

How much gap should be left between D-rings and mounting poles?
For optimal performance leave at least 0.5 ft between D-rings and poles, or consider reducing by 1 to 1.5 ft per side if needed for tensioning in tighter setups.
