There's nothing we can do to stop winters from turning cold, but we can wear The North Face Aconcagua Parka and make the cold disappear. The knee-length parka utilizes both down and synthetic insulation, creating a shield that traps heat from our body without allowing the cold to send a shiver down our spine. Synthetic insulation is used in key areas that are more likely to be wet out by snow and rain, since synthetic insulation maintains its warming properties while wet, so we can fearlessly step out into winter storms safe in the knowledge that we'll stay warm. The WindWall fabric helps block fierce gusts of frigid air, and the adjustable hood offers complete protection. So whether the dog needs to get out on a walk or we need to run to the grocery store, we stay protected from the elements.
