Trango Harpoon

These things are solid and perform great on waterfall ice routes, as expected for fully rigid crampons.

The only reason I can't give it five stars is because of the amount of work it takes to switch from dual to mono point (lots of little bits and pieces), and that it didn't come with antibot plates which should be required for all vertical rail crampons, in my opinion.

They fit my rockered sole Scarpa boots perfectly.
