For protection from the wind and cold during more aerobic outdoor activities, the Jack Wolfskin Men's Icy Trail 3-in-1 combination is the go-to solution. It consists of an insulated, windproof gilet teamed with a stretchy fleece jacket. Both garments are designed for mutual compatibility and effective moisture transport. The gilet keeps the torso warm and helps to counteract the wind-chill effect. This makes the Icy Trail 3-in-1 very well suited to trail running or cross-country skiing.
