MEC Obsession Hoodie with Polartec

Astonishingly breathable and packable, the MEC Obsession Hoodie uses breakthrough Polartec Alpha for warmth with air permeability. Most insulated jackets have a tightly woven outer layer, which limits their breathability. With a light soft shell fabric covering the insulation and stretch panels through the back and underarms, the Obsession offers venting that won’t shut down your ability to move. It’s DWR-treated to shed water when you wear it as an outer layer, and the streamlined cut works as a mid-layer for alpine climbing and skiing.
