Dig in with these ski binding crampons from La Sportiva. Compatible with most TLT style tech bindings, these superlight crampons are surprisingly resistant to all manner of bumps and bruises. The reassuring grip on icy surfaces will only cost you 69-84 grams (2.4-3.0 ounces) per ski.
As metioned in our article on La Sportiva Bindings, these attach easily to the RSR and RT binding crampon receptors.
UPDATE: This crampon is now available under the ATK brand.
