Follow-up inspections have shown that there is an assembly problem affecting individual Mammut / Snowpulse avalanche airbags from the Winter 2011/2012 and Winter 2012/2013 production seasons. The problem is an improperly screwed in connector between the deployment mechanism and the venturi valve.

If customers identify a problem we advise them to discontinue use of the airbag immediately. If this is the case, please contact Mammut customer services to arrange a repair.
The recall affects Mammut and Snowpulse avalanche airbags with Inflation System 2.0 from the 2011/2012 and 2012/2013 production seasons. You will find instructions on how to determine the production season of your avalanche airbag below.
