Summary: Naturehike's travel mattress with a high R-Value. Item Description: The Naturehike Tuye 8.8 CNK2450WS015 Mummy Regular Wide mattress will reliably insulate you from the cold ground in extreme conditions. A high R-Value of 8.8 guarantees effectiveness even in very low, sub-zero temperatures, making the mattress suitable for winter expeditions and camping. Its three-layer 3D construction, supplemented with aluminum, is unmatched in terms of protection against the cold, while the anatomical mummy shape perfectly mimics the natural lines of the body, ensuring comfort during sleep. The shape of the air chambers ensures even weight distribution, and the mattress's finish prevents slippage and is pleasant to the touch. This model is equipped with a reliable, leak-proof valve: its special double design allows for easy inflation (using the included bag) and equally easy deflation. You can easily roll it up into a compact form and pack it into the included cover.
