TATTICO is designed backwards from most pumps. The hose and valving is hidden inside the inner tube delivering up to 10% more air per stroke compared to pumps of similar length. Its adaptable cup seal grows with the tube resulting in ultimate efficiency at all temperatures. A heat sink hidden at the end of the barrel keeps the rest of the pump cool, even at high pressures. It also uses 2 thin tubes separated by an insulating air gap to keep hands cool.
