Hikenture High R-value 6.2 Air Mat 【8.5cm Extra Thick ● Ultra-Lightweight ● SGS Certified】 Size: L (196*64*8.5cm) Used only once for tent camping during my first mountain climb in December of this year. I think it's an excellent mat that prevents you from feeling the cold of the winter mountain ground. For reference, as shown in the Amazon image photos, the price is 11,880 yen. An air mat with high insulation and lightweight, compact storage. Also listed on other flea market sites, Rak◯uten Points' ◯ku◯, so I will delete it if it sells there. #OutdoorMat #AirMat #SleepingMat #Hikenture #WinterMountaineering
