Helmets... usually a contentious and much debated issue.

Climbing helmets are designed primarily to protect your head from falling rocks, rather than from a fall. They're certainly worth considering when summer and winter climbing, gorge scrambling, canyoning, off-road cycling.

If you're organising a group of novices or children then they should be considered essential. Otherwise it has to be an informed decision.

More information is available from the The British Mountaineering Council (BMC) in this article about climbing helmets.
