Hey everyone, I'm planning a trip to Mont Blanc in August and I wanted to know if the Trango S Evo's would be warm enough for the summit day. I've climbed with them on the massif before in early spring (May) and they were fine, but we didn't spend much time above 4000 meters. I figured they would probably be adequate especially since we're staying in a refuge; does anyone have any thoughts/experience here?

Thanks,
Mike
