Karakoram will participate this year in the hardboot segment and the Karakoram Guide HB is one of the lightest hardboot bindings on the market. They work with the same highly responsive 'active joining' connection as their softboot bindings. Here too, the lever ensures a super tight connection. The binding is a one size fits all and of course comes with both tour and ride interface. Of course you can omit the tour interface and replace it with a tech binding.
