The CASSIN X-DREAM tool was the result of input and design refinement from expert climbers and engineers on both sides of the Atlantic. One of Italian climbers responsible for the final product is Matteo Rivadossi, who is no stranger to hard routes on ice, snow, scrappy rock, and wildly-overhanging caves.
Here's Matteo training with the X-DREAM tools on an Italian route graded D12. (M grades are for "mixed" and D grades are for "dry", most high-end "M" routes are now free of any ice, so the "D" makes more sense.)
