Sea to Summit UltraLight Self Inflating Mat Small orange

From backpackers trying to shed grams to car campers who want glamping luxury, the range of self-inflating mats provide consistent warmth along the full length of the mat in a compact, comfortable, easy-to-use package.

Delta Core-V
In the lighter models, Delta Core-V vertical coring technology is applied to remove 20 % of the weight and bulk of the mat's polyurethane (PU) foam. Sea to Summit uses sophisticated pressure-mapping data to define body contact areas which becomes the blueprint for the  distinctive graduated core pattern. In body contact areas where extra warmth and support is needed - shoulders, hips and feet - the vertical core holes are smaller. In the less critical areas, more foam has been removed to minimise the weight and packed size. Delta Core-V technology is used in the Ultra Light SI and Camp Mat SI models.
