In reporting its results for the first four months of this year, Conzzeta Group said its sporting goods company, Mammut Sports Group, had the best performance, posting revenue growth of 12.3 percent to 76.4 million Swiss francs (€50.4m-$70.3m), helped by strength in reorders of winter goods and good orders for the summer. Germany and Switzerland, Mammut’s core markets, performed well, with growth coming from Italy and Japan as well. Some export to Eastern Europe and Asia were hurt by unfavorable currency effects. The company said demand for outdoor products is strong, but a slowdown is being seen in the U.S., where consumer confidence is low.
