Envelope Sleeping Bag Naturehike U350 Hollow Cotton Hooded Brown

Envelope Sleeping Bag Naturehike U350 Hollow Cotton Hooded Convertible Brown

Envelope Sleeping Bag Naturehike U350 is a versatile piece of equipment designed for camping and active leisure, featuring a convertible model that can be fully opened into a blanket. This outdoor gear effectively retains warmth with a comfort temperature of +1°C, shielding the user from moisture, dampness, cold, and wind during overnight stays. Constructed with a 190T polyester water-repellent outer coating and 350 g/m² hollow cotton filling, it ensures a hygienic and pleasant feel against the body while maintaining a total weight of 1700 g. The hollow cotton insulation technology utilizes synthetic fibers with a hollow core to trap air, mimicking the thermal properties of natural down while providing superior performance in damp environments. This specific insulation ensures the bag remains breathable and maintains its loft even after repeated compression, providing consistent thermal regulation throughout the night.

Features

• ➤ Convertible Design: The zippered closure allows the unit to be fully opened for use as a blanket or combined with another bag to create a double model.
• ➤ Thermal Insulation: Filled with 350 g/m² hollow cotton and cotton feather imitation to achieve a comfort rating of +1°C and an extreme limit of -13°C.
• ➤ Water-Repellent Shell: The 190T polyester outer material resists moisture and wind, keeping the internal environment dry in outdoor conditions.
• ➤ Spacious Dimensions: Measuring 220 x 75 cm when unfolded, the hooded shape comfortably accommodates tall adults and ensures optimal positioning.
• ➤ Compact Portability: The gear folds down to 27 x 44 cm and fits into a specialized storage bag for efficient transport.
• ➤ Maintenance: Technical fabrics and synthetic filling make the sleeping bag fully machine washable for easy long-term care.

When trekking through the high-altitude forest paths of the Tatra Mountains in Poland, the hollow cotton insulation provides necessary warmth as night temperatures drop toward the comfort limit. The water-repellent 190T polyester shell prevents dampness from mountain mist or ground moisture from penetrating the interior during rest. Users can transition the gear from a secure hooded bag to an open blanket when resting in sheltered mountain huts to better regulate body temperature. This adaptability ensures a healthy sleep cycle regardless of the shifting weather patterns found in Central European mountain ranges.
