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 inflate three times faster thanks to the larger opening and one-directional inflation. Like all Therm-a-Rest mattresses, the BaseCamp is manufactured domestically for quality and environmental protection reasons. A compact stuff sack is included.
