The Petzl Sirocco is an ultra lightweight climbing and mountaineering helmet with reinforced protection. Entirely adjustable and adapts to all head shapes. 

Petzl says:

The SIROCCO is designed to respond to the needs of climbers and mountaineers for reduced weight and for protection. Its head-covering shape, lower in the rear, offers reinforced protection. Optimized volume on the head, along with excellent ventilation, provide maximum comfort.

Petzl's Sirocco Helmet is the lightest climbing helmet available today. It's so light and comfortable that you don't realise you're wearing it. It's a great choice for those on big trips with long walk-ins where every gram counts.

The polypropylene foam not only has excellent energy absorption qualities - it's also quite soft. This allows the Sirocco to mould with the contours of the head for a comfortable fit. We really like the magnetic buckle, as it's super quick and less fidgety to buckle up.

This updated version now features a rigid crown piece in injected expanded polystyrene. It also extends further down the back and sides for better protection. It only adds a little extra weight but you do get extra durability.

I have just upgraded to the latest Sirocco helmet having had the bright orange original for years. Still incredibly light-weight, I just don't notice having it in. The new colouring is more discrete and the plastic top will add to the durability. I hope to never have to fully test its capabilities but its lightness gives me no excuse to not wear it.
