Description of C.A.M.P. XLC Nanotech Semi-Automatic Crampons Aluminum is softer and more rigid than steel. This makes it both less durable and more breakable. But it is also much lighter. This is why the XLC series crampons (lightest 12 point crampons in the world) have been a smash hit ever since they hit the market. To take advantage of the specific properties of both metals, the new XLC Nanotech crampons use innovative Sandvik Nanoflex® steel alloy attachments that line the bottom of the critical front points. The attachments make the front points sharper for higher penetration and increased security. They also make them significantly more resistant to wear and tear. Ideal for expeditions and low-angle mixed routes where light weight and high strength are both at a premium. Features: Weight: 565 gr.
