This is a Z Lite Sol small size (authentic) closed-cell mat, a THERMAREST (Therm-a-Rest) classic. I only unfolded it once indoors after purchase, and have not used it outdoors. There are no noticeable stains or damage, and it is in very clean condition overall. It requires no inflation and is ready to use simply by unfolding it, making it a popular model for mountaineering, camping, car camping, and disaster preparedness. The small size makes it lightweight and compact, especially recommended for women and those who prioritize packing size. 【Condition】 ・Only unfolded indoors ・Never used outdoors ・No tears or missing parts 【Specifications】 ・Closed-cell mattress ・Foldable ・Small size ・Uncut ・Authentic Please purchase only if you understand that this is a used item.
