General purpose, cold-busting combo: The Men's Roller Coaster 3-in-1 Jacketis a super-versatile fleece jacket and softshell gilet combination. The inner jacket is made from Jack Wolfskin's stretchy Nanuk Dynamic fleece. This provides good mobility with a snug, body-hugging fit fit. The soft reverse side blots up moisture from the skin and transports it to the outside, leaving you feeling nice and dry, even during more active phases.The outer gilet keeps the wind off your torso and prevents undercooling. The gilet is also so breathable that it supports the wicking performance of the inner jacket perfectly. And if you only need wind chill protection or an insulation layer, simply zip open the System Zip and you can wear the gilet or the fleece on their own.
