In words

Intro
One of the best lightweight canister backpacks out there. Minimalist in design, it's made from thin, lightweight yet super tough materials. The exterior is in water-repellent Cordura, the front panel in waterproof X-Pack. It has one large internal compartment with netting for shovel and probe (some like it, some don't), and a small pocket at the top for essentials. Designed for speed touring (see the thin shoulder straps and flask holder), it's not particularly comfortable if very full, so can't be compared to a classic touring backpack. The ski carrier is diagonal or A-frame using the straps included, and there are two ice axe holders. The back is ventilated and has a removable structure for when you need to keep the weight down. For one push ascents with added safety.

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.
