The Prima Vapour 60 is all about providing performance with a minimum weight and packed size. It features an insulating layer of PrimaLoft® bonded to the top inner surface of the tubes for optimum performance and the external channels allow the sleeping bag base insulation to loft effectively, filling the gaps for enhanced comfort and heat retention. The PFC-free airbed has our unobtrusive Pump Sack compatible Peak valve designed to provide rapid inflation and deflation.
