The group of people getting ready to ski should ensure that they have all the necessary ski equipment, such as skis, ski poles, boots, bindings, and helmets. Additionally, they should be wearing suitable clothing for the cold and snowy conditions, which includes layers for warmth, waterproof and insulated jackets and pants, gloves, goggles, and a hat or balaclava. The backpack in the image indicates that they may also need to carry essentials like water, snacks, sun protection, and possibly a small first aid kit. If they plan to venture off the main ski slopes or engage in backcountry skiing, it is crucial to have avalanche safety gear, such as an avalanche beacon, a shovel, and a probe. Moreover, they should be familiar with the ski area, trail maps, and safety rules, as well as their skill level and limitations, to ensure a fun and safe skiing experience.
