The Biancograt is one of the most famous and aesthetic routes in the Alps. It leads to the 4,048-metre-high Piz Bernina, the only four-thousand-metre peak in the Eastern Alps.

Something is happening on the ski boot market: the BOA® fastening system allows ski boots to be adjusted more easily, more quickly and, above all, more precisely. Instead of having to fiddle with several buckles, a twist lock ensures that the boot fits evenly around the foot via a cable system. The shoe wraps around your foot like a Boa snake and offers you a secure hold in a wide range of conditions. There's only one thing left to say: simply BOA!

The danger of avalanches accompanies us winter sports enthusiasts, but modern equipment such as avalanche airbag backpacks can significantly improve the chances of survival in an emergency. Various scientific studies have investigated how effective avalanche airbags actually are. In a study on the effectiveness of avalanche airbags by Haegeli et al. (2014)[1], it was found that an inflated airbag can prevent around half of all fatalities in avalanche victims caught in an avalanche of size 2 or larger. The non-deployment rate found is 20% and is therefore the limiting factor of the airbag.
