What should I wear under my Thermologic Jacket or Vest?
Always wear a base layer under your Thermologic Jacket or Vest. Depending on the product purchased, your Thermologic Jacket or Vest may be suitable as a heated prime layer under your outer shell, or as your outer layer. Thermologic garments are designed to trap and heat the air inside the garment to keep you warm. Please note that by adding extra insulation under a Thermologic garment, you will feel less direct heat from the trace.
