The North Face Freedom Triclimate Jacket offers the versatility of a shell jacket for layering in warmer weather and the comfort of an insulated jacket for colder days. The outer 2-layer shell features a DryVent membrane that is highly waterproof and breathes to release sweat vapor. The removable inner is loaded up with Heatseeker insulation and features zip-in compatibility with the waterproof shell for optimum heat retention.
