I ski with a pack. Mainly theres just a water pouch, a camera, extra mittens, lowlight goggles, and some granola bar/ snacks in the pack. Its pretty small and I dont mind skiing with it. But if I am going to get serious in the park I usually try to get someone else to carry the pack for me. The stuff I carry with me is usually just my valuables and stuff so I dont need to leave my pack in the lodge or in a locker.
