You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Petzl Sirocco Helmet Description

  • Brand : Petzl
  • Season : Perennial
  • Code : 5014131
  • Weight : 0KG
  • Helmets - Petzl Sirocco

    This sets a new benchmark for lightweight climbing lids.  It dispenses with the tradition idea of a hard shell and instead is constructed using only closed cell foam.  This means the helmet is very, very light, superbly well ventilated and ridiculously comfortable and still offers excellent impact protection, thanks to the mechanical properties of expanded polypropylene (EPP). The minimalist fabric strap also contributes to its lightness and features a new magnetic buckle which allows the chinstrap to be attached with one hand.  We can vouch that this works very well and is easy to use.  The Sirocco even has headtorch clips.

    While possibly not the most durable climbing helmet around, the Sirocco fills a niche for elite climbers, pushing the boundaries and looking to save every gram to achieve success.
