This is an inflatable mat with excellent sleeping comfort. It's been a year since I purchased it, and I've used it about 5 times for car camping. I used a cover when using it, so I think it's hygienic. There are no air leaks, and I believe it can be used comfortably in the future. 【 SPEC / Product Specifications 】 ■ Brand Name: NEMO Equipment ■ Product Name: Roamer XL Wide ■ Product Model Number: NM-RMR2-XLW ■ Color: - ■ Size: 198 x 76 x 10cm, Storage Size 40 x Diameter 25cm ■ Material: 50D (Top) / 75D PU Stretch Polyester (100% PCR) ■ Weight: 2.27kg ■ Country of Origin: - ■ Insulation: Open Cell Foam ■ R-value: 6.0 ■ Accessories: Dedicated stuff sack, compression straps, Vortex pump sack, repair kit ■ Features: ・Provides the best sleeping comfort with a combination of 10cm thick, hollowed-out foam and brushed stretch material. ・The Flow Core structure allows for setup and storage in less time than conventional models. ・Can be stored in half the size of a typical mat of the same size. ・Vortex pad pump is standard equipment.
