Naturehike Ultralight Square Standard R3.5 CNH22DZ018 Black Travel Mattress. 6975641888567. A spacious travel mattress for a backpack, bike pannier, or even a bushcraft bag – the Naturehike Ultralight Square Standard R3.5 CNH22DZ018 inflatable mattress. Who remembers the days when hikers with huge backpacks with external frames would wander off, half their belongings strapped to the outside of the backpack? Today, manufacturers are competing to make their equipment lightweight, space-saving, and durable. Travel mattresses are one such product. Next to self-inflating mats, they are probably the most frequently chosen travel "beds," primarily due to their size and weight. Thanks to their compactness, inflatable travel mattresses are a popular choice among cyclists and motorcyclists, whose panniers have very limited capacity.& xa0. This lightweight hiking mattress has standard dimensions – 183 x 64 x 7 cm. Certainly, few will feel its weight during a hike, as it weighs less than 550 g! The Naturehike Ultralight Square Standard R 3.5 CNH22DZ018 is designed for three seasons – from spring to autumn. This is made possible by an R-Value of 3.5 (Resistance-Value). If after a long day you don't feel like inflating the mattress yourself, don't worry – the Ultralight Mummy model comes with a special inflation bag. This will allow you to save your remaining energy, for example, for preparing a campfire.
