R-Value 2.2 Good down to 2°C

With A full 4 cm (1.5 inch )of foam, FlexMat Plus is the thickest, most-comfortable closed-cell mat available. It is highly versatile for stand-alone use and will increase warmth and puncture protection for inflatable mats. The rapidly-deployed folding form makes setting up and striking camp a breeze.

Extend your 3 season inflatable mat with FlexMat Plus

For a relatively small outlay the Flexmat Plus can be used as a great way of extending your 3 Seasons air mat to be part of a winter sleep system. For example place your air mat with a R-Value of 3 on top of the Flexmat Plus with R-Value of 2.2 and get the R-Value equivalent of 5.2 (Typical operating temperature down to -20°C).

Another benefit of using the 2 mat system in the winter is, should your inflatable mat develop a puncture, you at least have some reasonable protection from the cold from your FlexMat Plus.
