Size and fit Dimensions: 79in x 79in (200cm x 200cm). Sized to fit QINNLIIOP tents and most fourperson tents. Larger than many common mats for fuller floor coverage. Key benefits Triplelayer protection: aluminum foil for heat reflection, EPE foam for insulation, and a waterproof PE backing to block cold and moisture more effectively than singlelayer mats. Stabilizes your sleeping area: antislip dots on the surface reduce shifting so the mat stays in place during the night. Lightweight and compact: weighs just 0.2 lbs and folds to a 21in by 6in cylinder for easy packing in a bag or backpack. Durable construction: 0.8mm thickened foil resists punctures from rocks and roots; labtested for 200+ fold cycles for extended service life. What makes it useful Combines heat reflection, compressible insulation, and a waterproof base to improve comfort and dryness on hard or cold ground. Oversize dimensions provide more coverage under sleeping bags, pads, and camp gear. Antislip surface and tearresistant materials reduce the need to readjust during sleep and help the mat last through repeated use. Materials and performance Aluminum foil layer reflects body heat back toward the user. EPE foam layer adds cushioning and thermal resistance. Waterproof PE backing prevents ground moisture transfer. 0.8mm foil thickness and labtested folding durability give reliable field performance. Practical use scenarios Car camping: place under sleeping pads or air mattresses for extra insulation and moisture protection when staying at established sites. Tent trips: use as a tent floor layer in QINNLIIOP or other similarly sized tents to increase warmth and prevent ground dampness from reaching sleeping gear. Lightweight backpacking or festivals: fold into its compact cylinder and stash in a daypack for quick ground protection during rest breaks or overnight stays. What you get A compact, lightweight, and tearresistant ground mat that adds insulation, moisture resistance, and stability to your sleeping setup without adding bulk.
