【Built-in Pump for Fast Inflation】With the built-in foot-operated air pump, you can inflate the camping mattress fast in 2 minutes. No need to pack an extra pump to save backpack burden, and worry about batteries on your trip. Note: Please make sure to close the 2 valves on the back of the pillows before pumping air. Open the valves under the pillows then the sleeping mat could be deflated in seconds. 【Double Size & Extra Thickness】This double camping mat is designed with a super large size: 76" X 52" and 4 inches extra thickness after inflating, which provides generous space and strong support for 2 adults to sleep comfortably. Perfect camping accessories to share with your girl/boyfriend, wife/husband, kids, friends, and dogs. 【Waterproof & Scratch-resistant Materials】The fabric layer of this camping sleeping pad is made of thickened 400D nylon that protects the mat from scratches and helps to hold your body from sliding. TUP Inner Coating seals air in place, preventing air leakage and water infiltration. 【Lightweight & Ultra Portable】The camping pad can be folded down to 6.8" X 14.8" and weighs only 5 pounds, just fits into a backpack or suitcase without adding any burden to your trip. Outdoor mats are also useful for daily activities.
