Thank you for viewing. This is the EXPED SynMat UL M. I purchased it for winter mountain climbing, but I'm no longer going on serious climbs, so I'm selling it unused. Retail price: 20,900 yen (tax included). This is a highly-regarded inflatable mattress from EXPED, popular on PORTAL. The SynMat UL uses microfiber insulation, providing excellent warmth while remaining lightweight.
