water bottle (not there permanently, I take it out after class to wash/refill it)  small towel  legwarmers (out now since it's summer)  lip balm (works great as a moisturizer on knuckles, BTW)  Tiger Balm (haven't used it for a while, though. That's a good thing)  extra tights That's about all I keep in mine. It's kept small on purpose. I started off with a larger bag and just kept adding stuff into it until I got frustrated with it's size and got something smaller. Maybe I'm being a minimalist, but I'm there to dance, and all I need is lots of energy (but you can't store that in your bag).

So what do you guys keep in yours?
