These are your Swiss army knife skis. Your one-ski quiver. All-Mountain skis are designed with versatility and performance in mind. This category takes up a huge portion of the test, so don’t be overwhelmed. Try to stick with a waist width and work from there. Most skis in this zone are between 85 and 95 mm wide, with some exceptions on either end. If you’re looking for one pair of skis to use every day, this is your category.
