The Easyflyte 670 is a self inflating camping pad which uses sponge to suck in air and self inflate. It will inflate to 3 cm high combining sponge and air for a comfortable nights sleep.
Three fabrics are used to make these self inflating sleeping mats. The inner fabric is a high quality sponge which has three functions. These functions include sucking in air to inflate the mattress, providing comfortable padding and insulation from the cold.
Above the sponge is a TPU seal composite layer. This layer adds further insulation and stops water leaking through to the foam layer. It also acts as addition protection from punctures.
The top layer of the self inflating sleeping mat is made from 20D nylon. This is the first layer of protection and insulation and the most durable layer. On top of this layer is a logo which uses non slip silicon to help keep you on the mattress.
The valve on tee sleeping mats works a little differently to conventional air mattresses. When the valve is fully open the sponge expands sucking air into the mattress. This works the opposite way to what you would expect. The longer you leave the valve open for the further the sponge will expand sucking in more air.
Once the desired level of inflation is achieved close the valve and enjoy a good nights sleep. It is a good idea to leave the valve open for as long as possible. You can also blow into the the valve with the first plug plugged in to increase mattress firmness. However self inflation will achieve the most comfortable level of infaltion for most people.
