Camp USA's Tour Nanotech Crampon weighs a little over a pound, which is extremely light considering it's made of steel. Most steel crampons are too heavy or bulky for most ski mountaineers, but the Tour's lightweight, compact, ten-point design makes it easier for skiers to opt for steel when there's ice and rock between you and the objective. Instead of the traditional chromoly steel construction, Camp USA used Sandvik Nanoflex stainless steel that's 70% stronger and 20% stronger than standard chromoly. Since it's stronger, the Tour's frame is much slimmer than normal crampons for compact convenience.

By using Sandvik Nanoflex Steel, CAMP was able to make their Tour Nanotech Crampons lighter than standard steel. The stronger and more durable steel allows these crampons to be thinner than the average crampon which results in sharper points that won't dull as quickly and will never rust. Includes anti-balling plates to keep snow from clogging up your points.

The lightest steel crampons in the world! Sandvik NanoflexA(R) Steel uses nanotechnology to create a superior metal that is 30% stronger and 20% harder than traditional chromoly steel thereby allowing us to use a thinner cross section (1.8mm) that results in a crampon that is not only lighter, but stronger, more durable and stainless by design. The thinner cross section also creates sharper, thinner points that penetrate hard snow with ease. The automatic binding is compatible with most models of A/T and Tele boots.
