A true JACK WOLFSKIN classic that has been part of our range for more than three decades: Our double jacket technology – one jacket, three ways to wear it.
Our 3in1 system combines two jackets, e.g. an all-weather and fleece jacket which can be combined using a zip system.
The front zip on the inner jacket is attached to the second zip on the outer jacket; fastening loops on the sleeves and at the neck prevent it from slipping.
Both jackets need to have a system zip of the same length. They are generally "SHORT" and "REGULAR". Other lengths include the EXTRA LONG System Zip for a full coat length and the KIDS System Zip for children and teenagers.
3in1 Regular is the normal length system zip.
