Any Experience with Double Layer Ventilated Jackets?

[PhilK]

I know the Ultrabreeze is a successful design, and it is a 3 layered mesh fabric, but I recently came across the below product that is 2 layer mesh. I'm wondering if anybody has had any experience with this?
It gets super hot in Australia and even in my 3 layer mesh jacket I sweat like crazy, so wondering if a 2 layer one will work better for me but will give it a miss if it's not as good for sting protection!
