I purchased this online last month. I've only used it a few times indoors, just to lie down on, but it doesn't suit me as I have a weak back, so I'm selling it! I think it can be used as a mat for camping or in the event of a disaster! - Model Name: Field Station - Material: [Body] Foamed PE/PE aluminum film/Polyester (belt) - Size: Approximately 60cm x 180cm - Weight: 400g - Thickness: Approximately 20mm - Waterproof, Lightweight *Please check my profile to avoid any problems. #CampingGear #CampingMat #FieldStation #WaterproofMat #LightweightMat #CampingGoods
