Great craftsmanship

I double-checked with their customer support about edge curve allowances before ordering, and they were very helpful. The final sail size was exact corner-to-corner. Clean stitching and no loose threads.

The BEST shade ever!!!

This is a MUST buy if you want a sun shade. Ours has been up a year and has went thru storms, snow, 50 mph winds (no joke- we live in SW Kansas) and it has held up! Corners have not ripped, have no holes, nothing. Like brand new after a year. If this one ever dies, I will definitely order another!

Perfect custom fit and fast turnaround!

Measurements were spot-on and the stitching around the D-rings is heavy duty. Shipped much faster than expected for a custom order.

Looks good and easy to install

Good quality easy to install looks good

No sagging on the long edges

Was worried that an 18ft long side would sag down into our heads, but the curved edge design keeps the entire rectangle pulled taut once tensioned. Very smart engineering.

Held up great through high winds

We live on a windy hill and I was a bit worried a custom 14x16 sail might stretch or rip. We’ve had gusts over 35 mph this spring and this sail barely flinched. The reinforced corners take tension really well. Definitely make sure you use strong hardware and pull it tight.

Clean look, blocks the heat

Looks modern and cut the glare on our back sliding doors instantly. Excellent product.

Best shade sail we've owned

Custom sizing without the custom price tag. Highly recommended!

Worth every penny

Great price for custom work. Looks beautiful over our garden courtyard and keeps the blazing afternoon sun away.

Made our Arizona patio usable again

Living in Phoenix, our back patio was completely unusable from May through September. I ordered an 11.5ft x 19ft custom breathable shade sail in sand color. It took about 2 weeks to arrive. The material noticeably drops the temperature underneath by at least 10–15 degrees. Even let some breezy airflow through so it doesn’t balloon up like a parachute in the wind. Incredible value compared to what local awning companies quoted us.

Keeps our pool cool for the kids

Strung this over half of our rectangular inground pool. The kids can swim for hours without getting sunburned, and the breathable mesh lets the hot air rise right through.

Exactly what we needed for an awkward space

We have an oddly shaped deck that none of the standard sizes at Home Depot could cover. Sunlax made it to our exact dimensions. Tensioned it up with turnbuckles and there's zero sag. High quality fabric!

Total game changer for our pool deck

We needed shade over the shallow end of our pool for the kids. Standard sizes were either too narrow or way too long. The custom ordering process was super straightforward. We anchored two corners to the house fascia and two to steel poles set in concrete. It looks like a high-end commercial resort setup. Fabric breathes well and allows heat to escape.

Replaced an old saggy generic sail

Had an off-the-shelf sail before that was 2 feet too short and flapped constantly. Having a properly sized custom rectangle stretched tight makes the backyard look like a high-end resort.

Exactly the dimensions we needed

Couldn’t find an 8x14 anywhere in local stores. Sunlax made it exactly to my specs and the stainless D-rings are very heavy-duty.

Fast turnaround for custom work

Ordered custom sizing and it arrived way faster than expected. Great value compared to custom canvas shops.

Great solution for our two-car driveway

We don't have a garage and the summer sun was baking our cars. Anchored a 16x22 ft custom rectangle between the house and two steel poles. Interior car temps dropped significantly. Sturdy fabric and heavy stitching.

Simple to order, easy to install

Took our measurements between the four posts, subtracted about 10% for hardware tensioning, and ordered. When it arrived, it strapped right on with turnbuckles without needing any adjustments. Solid craftsmanship.

Fit like a glove!

Entered my custom measurements, hung it up this weekend, and it fit like a glove. 10/10.

High quality custom sail

Well-made, dense fabric, and blocks the heat effectively. Very happy with it.

Heavy duty and great color

The charcoal grey matches our siding nicely. Super thick material and reinforced edges. Couldn’t be happier.

Way better than generic off-the-shelf sails

I replaced a cheap standard sail that ripped at the corner after one season. You can immediately feel the difference in the Sunlax sail—the webbing runs all the way along the perimeter and the stainless D-rings are solid.

Waterproof version kept our furniture completely dry

Went with the waterproof PES fabric for over our patio sectional. Installed it with a slight slope as recommended so rain runs right off. Survived a heavy thunderstorm last weekend with no pooling. Very impressed.

Perfect fit for our patio

Size was exact to the inch. Super easy DIY install with turnbuckles.
