All lovers of car camping will appreciate the luxurious features of the large BaseCamp mattress. This warm and comfortable mattress has a 5 cm thick, self-inflating foam with an R-value of 6.0 for even more enjoyable nights under the starry sky. The thoughtfully designed cover is lightweight and feels soft to the touch. The versatile, self-inflating mattress features a high-quality WingLock valve, allowing it to be inflated three times faster thanks to the larger opening and one-directional inflation.
