In words

Intro
Designed for ski touring and mountaineering, for those situations where you need to find the right balance between lightness, bulk and comfort. Easy to put on while wearing skis, it's reasonably comfortable. A special mention goes to the double gear loops, which are thin but coated so they maintain their shape without being bulky and are always easy to find.

Intro
Safety, a culture of doubt

Beyond the basic definition, there’s nothing as variable as snow conditions and the human psyche when under emotional stress. That's why, after purchasing the right self-rescue kit and airbag backpack, it’s paramount you do your research, train, scrutinize your decisions and, if necessary, opt for plan B. And, at least for now, don’t rely on artificial intelligence.

Intro
Products for mountaineers

Once you’ve chosen your skis, boots and bindings, your thoughts then turn to harnesses, crampons, ice axe and helmet, though perhaps not everyone, and not straight away. While it’s true that when starting out, especially for those transitioning from resort skiing who just want to start surfing some pow, the important thing is to get self-rescue equipment. It’s equally true, however, that the sport we love is a combination of two words: skiing and mountaineering.

Split All Mountain
Intro
Boards, boots, and bindings for splitboarding

Materials are evolving, which is increasing the opportunities for pushing the boundaries of mountaineering splitboarding. It’s no longer just about easy tours, a few jumps and a beer. Thanks to innovative new setups and growing knowledge within the community, long ascents and steep terrain no longer intimidate.

Intro
Skimo bindings

They’re probably the element of your setup that’s evolved the most and seen the most crossover between disciplines. Which is why in general lighter bindings have adapted to make allowances for the trend for opting for wider skis, with hybrid drilling patterns and a greater selection of ski brakes. But the aspect that requires most scrutiny is the height difference between the front and rear pins.
