Opinions of MD Deluge Gore-Tex jacket & Grampian rain pants

I bought a MD Deluge Gore-Tex jacket last week and now having second thoughts about breathability and general performance for bushwalking. It is a very basic design, mesh-lined and has no pit zips or other ventilation. Also bought MD Grampian rain pants and unsure about those either. Does anyone have experience or opinions with either of these?

I originally posted this in the rain jackets thread but looking for opinions if anyone can help. I'm trying to decide whether to keep or return them, which I can do within 30 days of purchase.
