I can't answer that question accurately yet as I haven't dived in my suit yet. However, one of the guys in our club used his a few weeks ago and in water temps of 7 c managed to stay in for around 45 minutes....
Up until now I have been freediving in my scuba 6.5mm semi dry suit and have not been any warmer than the freedivers in their 5mm freediving suits....
Hope this helps...
