If you love the Formula and Speed Reader Jackets, you'll love the Men's Force Jacket. This innovative style is engineered with stretchable, breathable materials through every layer. The lining features Graphene, a specialized material engineered with highly conductive graphene to absorb body heat and evenly transport it throughout the fabric for excellent thermal management. KJUS even lined a special phone pocket with Graphene to keep your device's battery life strong in cold conditions. Intelligent KJUS FAST Thermo Core™ insulation offers warmth, breathability and 3D stretch. The face fabric is four-way-stretch for comfortable movement. Fully seam sealed and waterproof with a DWR finish, this jacket is ready for winter conditions. For comfort when carrying skis, this style has 3D-mesh panels inserted in the shoulders. Final touches include our patented KJUS AC-Vent™ ventilation system, which KJUS anatomically placed in the lower arms to help manage your microclimate.
