At Sea to Summit we set out to design a mat that was better than what was already available. ?Better? is of course a very subjective ambition: while we could have made the lightest, or the most compact mat ever designed, we ultimately went back to why we carry a sleeping mattress into the wild in the first place ? to give us a better night?s sleep. We?re really proud to present what we consider to be the most comfortable sleeping mattresses available. Happy sleeping!
