A mattress is essential for a good night's sleep. The Comfort Plus S.I. comes with a high thermal resistance and can achieve a low weight yet. This is worth its weight in gold when it comes to trekking! The smart, patented system of the valve prevents the PU foam in the mat from drawing air when packed together. So you can achieve a minimal pack size.

The R-value (thermal resistance value) is a measurement of a given material's resistance to heat flow. The higher the R-value, the greater the insulating effectiveness and the slower the heat flow through it. With increasing R-value the weight also increases. A mat with an R-value of 10 weighs around 3 kg. On a scale of 1-10 an R-value of 1 is suited for temperatures up to +7°C. Mats with a value of 10 are designed for temperatures down to -50°C.

Delta Core™ Technology
In these lightweight Sea to Summit models, the weight and mass of PU foam has been reduced by 20% using the vertical Delta Coring method. In the more stressed areas of the shoulders, hips and feet, the Delta Cores are smaller to guarantee a higher level of warmth and comfort. In less stressed areas, more foam is punched out to minimize weight and pack size.
