Do I need chalk for rock climbing?

Daniel Wade (Rock Climbing Manager) gives expert video advice on: What is a 'carabiner' and how is it used in rock climbing?; How should I pick my carabiners?; How should I pick my rock climbing shoes? and more...

Most climbers nowadays use chalk because it keeps your hands from sweating and it gives you a little bit more purchase on small holds. It's probably more important in sport climbing than it is in traditional or mountain climbing. You should use it, try it, and see what you think. I definitely use chalk if I'm going out locally but probably not going to bring it to the mountains.
