Replying to Hydration Systems

How many of you guys wear camelbacks and stuff while you ski?? Last year I just wore a little K2 one that had a bladder, straw and enough room for a little first aid kit and some lunch, that was cool but this year I got a day/freeriding pack with a hydration system, it's pretty cool but maybe a litte big to wear while jibbing and stuff. What do you guys do?
