Improve the comfort and protect the Kamaboko Inner Tent floor with this rugged Mat Set. The set comes with a ground sheet that goes under the Inner Tent and an inner mat that fits perfectly inside the Inner Tent. All DOD products are built to last but even the strongest tent floor can be damaged by rocks and debris under the tent. The 210D woven polyester protects the Inner Tent floor from damage. The polyurethane coating makes it waterproof to 5000mm so you can be confident that you’ll stay dry in the most adverse conditions. The groundsheet hooks to the outer tent ribs to hold it in place. The inner mat consists of 2 layers of 210D woven polyester with PU coating, encasing a ¼” (6mm) thick rubber pad. This makes the tent floor softer and smoother. It also protects the Inner Tent floor from the feet of furniture used in the tent. Available in 3 sizes to fit your Kamaboko. 210D woven polyester for durability. PU coating for a waterproof rating of 5000mm.
