I understood that coupet asked if the passage is possible without winter gear, if there is still snow or not... Based on my reply, two options would be possible - either postpone the hike or take winter gear... I can't agree at all that it's sensible to carry winter gear if there is no snow; most probably don't even have it at home, but it's different with a helmet and optional self-belay kit... I believe we are responsible people on this forum and I don't know why someone would give wrong information? If you only trust known people, then the forum is not needed! I can't imagine an answer if someone asks how much snow there is, how hard it is and on what slope...:-(
Good luck in the mountains and more patience!!!
