I only see a mesh back; the seat looks like a foam padded type with a partial nose.
The seat itself has to be the suspended mesh type to make the differences I'm talking about (which also include doing a better job of form-fitting/supporting the butt than the foam saddles do, at least for me).
The mesh back just lets air flow past better to keep your back cooler, and might help keep your back from being pounded if you're leaning / pushing bakc on it during bumps.
