Sea to Summit Comfort Light S.I.™ Sleeping Mat — Regular

Using Sea to Summit's Delta Core™ technology, the Comfort Light S.I.™ sleeping mat is for those of us who are looking for the perfect compromise between comfort and weight in a traditional self-inflating foam mat. Their Delta Core™ technique is a truly innovative approach to reducing the weight and bulk of the polyurethane (PU) foam core of their self-inflating mattresses. The patent pending coring process removes up to 40% of the initial volume of the PU foam, retaining enough for optimal support and comfort, while minimising the packed weight and size of the final mattress. At 5 cm thick, you can be sure of a great nights sleep, while the Sea to Summit R-value of 3.1 will give you plenty of insulation for 3-season comfort and still leave you with plenty of room in your pack for everything else.
