ZIP System Technologies

Our system zip ensures that the zips of the inner and outer jacket are compatible with the same type of system zip – regardless of the season in which the jackets were bought. All jackets also have loops and snap fasteners on the sleeves and in the neck area. These allow the inner jacket and outer jacket to be combined to form a double jacket – even without connecting them with the front zip.

The REGULAR SYSTEM ZIP is used in regular and long-length JACK WOLFSKIN 3-in-1 jackets, and primarily in our trekking jackets. 

Certain weatherproof and insulating jackets also feature the SYSTEM ZIP and can therefore also be used with 3-in-1 jackets.
