Sorry, this product is out of stock. We can notify you when this product is available:


The Petzl Sirocco is an ultralight mountaineering, ice climbing and multi-pitch climbing helmet, with reinforced protection and excellent ventilation. 

Designed to respond to the needs of climbers and mountaineers for reduced weight and for protection, its head-covering shape which is lower in the rear, offers reinforced protection. Optimised volume on the head, along with excellent ventilation, provide maximum comfort.

The Sirocco can also be used for ski mountaineering and backcountry tours as it CE-certified for ski touring - a new certificate recently developed by Petzl.

It should be noted though that this helmet does not meet the requirements of the EN 1077 standard for alpine ski helmets, so should not be used on pistes.

    Very light and comfortable

    The helmet has protection right around the head which means it not only protects against rockfall but also against side impacts, for example if a ground fall is experienced. It is super light and barely noticeable to wear. Top marks.

    love it. as light and

    love it. as light and comfortable as wearing a woolly hat. It also flexes so is unlikely to crack if it gets bashed around a bit which is what happened to a previous polystyrene petzl helmet i owned. fairly expensive but for me it was worth paying that little bit more for.

    I hate wearing a helmet

    I hate wearing a helmet and have never lasted a day with one still on my head. After taking a pretty scary head first whipper I decided I couldn't risk this attitude any longer. The Sirocco helmet is the first helmet that hasn't bothered me, it is so light I forgot it was on, it didn't hinder my vision in any way and I felt safe in it. they solve comfort issues though light weight materials and minimal nylon webbing, no plastic and padding that gets more in the way than anything else. This was also light enough on the head I imagine it being very breezy and cool in the heat as there isn't much material in contact with your skin. Petzl's magnetic clasp is also a welcome detail that tops on this fantastic helmet.
