Testers | 20 December 2011 | par : audrey

We tried to climb the Huayna Postosi in Bolivia next to La Paz at 6088m.

It was snowing up there and you needed crampons.

I therefore didn’t go up there with the Novadry boots, but at least up to the refuge at 5133m….

To get there, my Novadry boots resisted well in the powdery snow. They are completely watertight.
Whilst everybody else had wet feet and were stressed out because they couldn’t dry out their stocks in the hut at 0°C…. my feet were completely dry… they were very envious!!!!

Love the rain | 6 September 2008 | par : remy

Just like rain, snow falls from clouds. Different weather conditions lead to different types of precipitation.

Snow forms in high altitude clouds, where temperatures are extremely low.

Water vapour freezes around condensation seeds as ice crystals.

When they reach a critical mass, the crystals fall. As the crystals fall to the ground, the ambient temperature rises:

- if the temperature stays below freezing (0°C), the ice crystals stick together and make flakes that land on the ground. This is snow.

- if the temperature rises above freezing, the ice crystals melt. This results in wet, sleety snow or just plain old rain.
