Petzl Sirocco, Version II

The new Sirocco also ups its overall protection rating through the use of two different materials for shock absorption. The outer is the same, soft, expanded polypropylene that seems to bounce back from impacts and has proven extremely durable in the original orange. I’ve crushed mine into packs, have been hit by ice or rock countless times, and though it has the battle scars to prove it, the Sirocco has never let me down (and over the time I’ve had it, I’ve managed to crush a BD Vector and a Singing Rock Penta, while the Sirocco continues on).
