Sea to Summit have innovated to to make their range of Self Inflating mats thicker, lighter and easier to use. That innovation is Delta Core Technology. This technique reduces the volume of the foam by up to 40% which in turn reduces the packed weight and size of the mattress. The biggest advantage of the Delta Core technology is that it keeps the top and bottom surface of the foam in one piece, this ensures the mat is consistently warm along the full length of the mattress. 
We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats-that is, the problem of the foam trying to re-inflate as you’re packing up.
