An icon cannot be improved on, only developed further. Designers refer to this as ‘evolution’. In the case of the DS3.1, the clip has been enlarged and the twist mechanism redeveloped. Its predecessor is, however, still clearly recognisable.

New mechanism

Prodir has developed a new twist mechanism from scratch for the DS3.1.

It is now even more supple, comfortable and durable. Try it for yourself.
