How are Sea to Summit self-inflating sleeping mats lighter than others?

Our innovative design Delta Core and Delta Core-V strategically removes cores of PU foam where they’re no longer needed, which makes our self-inflating sleeping mats lighter to carry, whilst not compromising on warmth.

Our unique Delta Coring means that in thicker mats the outer fabric layer has full contact with the internal foam. This results in a more reliable connection and prevents mattresses suffering from delamination.
