Fluid Zone Full-Zip Jacket - Men's

The Icebreaker Men's Fluid Zone Full-Zip Jacket is a midweight midlayer optimized for high-aerobic pursuits like trail running in the shoulder seasons or even backcountry touring in wintertime. Icebreaker made this jacket out of a midweight merino wool blended with Lycra to ensure freedom of movement. Merino wool excels at thermal regulation, meaning it can warm you up when you're cold and also help keep your cool by wicking moisture and drying quickly after you work up a sweat. Merino wool is also naturally antimicrobial to reduce odors and increase freshness. Icebreaker paneled the underarms and sides with merino mesh to amplify ventilation and quicken drying time where you'll sweat most.
