  • Technologies:
    • Delta™Core™ technology: the innovative Delta™Core™ system maximises the comfort and thickness of Sea to Summit Self Inflating mattresses while minimising weight and bulk. 40% of the initial volume of the PU foam is removed in horizontal Delta-shaped cores, giving minimal weight and packed size. Importantly, the top and bottom surface of the PU foam remain completely intact. This ensures consistent warmth along the full length of the mattress and significantly improves bonding of the foam to the shell fabric, which reduces the chance of delamination.
