Thanks for answers! I think there is a mistake in the flyer, and the picture and price are for Salewa, although description for Petzl. They had the same kit in Hervis in City park in Lj for 120 eur. Probably I'll buy it. I estimate I'll need it max 10×/year, so I think it will be good enough and safe. The mentioned Salewa Toxo helmet is more comfortable (for my head) than Petzl Elios.
