The Naturehike M300 right sleeping bag in grey is the perfect choice for trips from early spring to late autumn. On warm summer nights, it can be fully unzipped and used as a duvet. Thanks to the cotton filling with a density of 300 g/m2, the sleeping bag effectively retains heat, protects against moisture, and provides good ventilation, guaranteeing a long and restful sleep. The inner layer made of washed cotton is soft and durable, while the sturdy Pongee 210T polyester shell is gentle to the touch and resistant to damage. Its innovative design allows for complete unzipping and connection to a second sleeping bag with a zipper on the opposite side. When packed into the compression sack, it measures 43 cm in height and 25 cm in diameter, making it extremely compact.
