In our lighter SI air mat models, we have removed 20% of the weight and bulk of the PU foam by using our vertical Delta Core-V method. We use sophisticated pressure mapping data that becomes the blueprint for our distinctive graduated core pattern.
Where extra warmth and support is needed for the body contact areas - shoulders, hips, and feet - the core holes are smaller. In the less critical areas, we have removed more foam to minimize the weight and packed size. Delta Core-V technology is used in our Ultra Light SI and Camp Mat SI models.
