This waterproof folding mat combines a reflective aluminum surface with a lightweight EPE foam core to deliver insulation, puncture resistance, and easy portability for outdoor use. Key benefits Protects gear and body from rough ground: the 9 mm EPE foam cushions against stones and branches and reduces pressure points when sleeping outdoors. Thermal insulation and heat reflection: doublesided aluminum foil helps retain body heat in cold conditions and reflects sunlight when used as a sun shield. Waterproof and wearresistant: the outer aluminum layer sheds moisture and resists abrasion for reliable use on wet or uneven surfaces. Lightweight and portable: folds compactly and stores in the included carry bag for easy transport and storage.
