Whether freeriding, ski tours or splitboarding: When you’re venturing off the beaten track and ditching the safe surroundings of the piste, your own – and your groups’ – safety becomes paramount. Avalanche protection starts way before you hit the slopes. On top of considering factors like risk of avalanches, weather conditions, territory and group dynamics when planning your route, the right equipment is key.

Fresh air, snowy landscapes and the gentle crunch of snow under your feet: Hiking in winter is one of those outdoor experiences that stay with you long after you’ve left the trails. But when getting ready to face those freezing temperatures, your warmest, thickest jacket should never be your first point of call. Especially when hiking, dressing in layers is key – after all, your gear needs to keep up with you every step of the way, whether brisk movements, strategic breaks, sun, wind or heavy snow. The solution? Multifunctional layers that can quickly adapt to any situation.

Trail running has a special appeal in winter: the air is sharp and clean, trails are usually deserted, and every route turns into something new with snow, ice, or mud. While summer trails get packed with people, winter means you often get your favorite routes entirely to yourself. That soft snow cushions each stride while being demanding at the same time. Every bump is hidden, every step needs real attention – perfect training for coordination and staying quick on your feet.

If you are into climbing or mountaineering, you definitely know one thing: strength, technique, and endurance aren't the only things that determine whether you succeed and stay safe. Your mental game matters just as much.

Mental training helps control fear, stay focused, and build genuine confidence. This post covers how to build up your mental toolkit for rock, gym, and alpine terrain – and why a solid headspace is gear you can't leave behind.

Your gear setup makes all the difference for staying safe, climbing comfortably, and actually having fun. When you've got the right essentials, you climb more safely and can zero in on your movement instead of worrying about your setup.

Getting married and having kids? Yeah… no. Lindsey Hamm never followed the Texan handbook for a “decent life.” Instead, she became an ice climber, mountain guide, and full-time mold-breaker. Her lifestyle is all about freedom, wilderness, and fun, but it’s also marked by loss, grief, and a fractured foot. And still, Lindsey pulls on her short leo tights, grabs her pack, and fires punchlines at life while roping up for her next ice climb. Her home isn’t pinned to a map – it lives in the people she’s lost, the ones she climbs for, and the joy of being unapologetically herself.

The ice has changed. It’s not like it used to be – less stable, less certain. The classic lines that professional ice climber Jonas Schild grew up on in the Bernese Oberland are harder to find now.

The way everything else disappears when he’s on the wall. The kind of day you’ll still be thinking about decades from now.
