Ortovox Knit Belt - The Knit Belt keeps trousers reliably and securely where they belong. The slightly stretchy belt is made from durable polyester, making it particularly robust and durable. The closure is an old acquaintance and also ensures a reliable and quickly adjustable hold for all Ortovox avalanche airbag backpacks. The woven mountain silhouette makes it a subtle detail that you can rely on.
