The Apeks ThermiQ Carbon Core sets new standards in base layer thermal protection. Comfort is guaranteed with the triple layer soft shell, combined with the technically advanced graphene lining to give the ultimate in warmth and flexibility. Triple layer soft shell fabric ensures the top keeps you warm in all environments. The ThermiQ Carbon Core can be worn on its own as a thermal rash guard in warm water or as an extra layer underneath a drysuit. Advanced lining is made from graphene wrapped fibers which acts as a superconductor, regulating skin temperature by transferring heat from warm spots to cold spots on the body. Breathable fabrics prevent moisture build up when used underneath a drysuit. Elasticated thumb loops keep the top in place when wearing under a drysuit.
