Thank you for viewing! This is a handmade mat set for use inside an ice fishing tent. The material is expensive expanded polypropylene (EPP), which excels in shock absorption, heat resistance, and insulation. It's thick, so it blocks the cold air from the ice. A silver mat with heat-retaining properties is attached to the surface. The main sheet can be folded in two, making it compact and convenient when loading it onto a sled. The step mat makes a huge difference in how tired you get when sitting cross-legged. Dimensions are as shown in the photos. The thickness is 40mm for the main sheet and 60mm for the step. The photos show one set, but I am also selling the main sheet separately. Bundling is possible. Please contact me if you are interested. #K-ZAN #VARIVAS #バリバス #クリスティア #レイクマスター #クリーク #creek #ATOLL #JJ CUSTOM #IMPACT
