A recall notice has been issued on a vital piece of winter gear made by a leading outdoor manufacturer.

Petzl Charlet says its Sarken crampons are susceptible to cracking near the front points and are advising anyone who has bought a pair to return them to their retailer for a swap. The company said that the potential lifetime of the crampons should be longer than has proved in use.

They have now stopped making the model. Importer Lyon Equipment stresses that no other Petzl Charlet models are affected. It suggests its Vasak crampons as an alternative.
