The Evernew Miyama Sleeping Mat is a full length sleeping mat designed for those who want warmth without the bulk. The foam ratio is adjusted to be lighter than conventional mats while the material itself is naturally non-slip. Aluminium is deposited on the surface — use the reflective side up in cold conditions to bounce body heat back to you, or flip it in warmer weather to stay cool. Although Evernew doesn't publish an R-value on this mat, we recommend it for the milder months (spring, summer and autumn in New Zealand) or to add extra insulation under your inflatable mat in winter.
