The design of wind blocking strip can be tightly wrapped by blocking the convection with external cold lips around the cap. U Neck Collar for better neck warmth. Internal pocket for cell phone and other small items to prevent frostbite. Everything is designed to maximize your heat retention
C-SHAPED WRAPPED DESIGN: The sleeping bag adopts C-shaped wrapping design, U-shaped cap cover, YKK two-way zipper, and the ratio of upper and lower pieces is 6:4, allowing more down cover on the top of the body, keeping warm and comfortable performance of sleeping bags. Minimizes difficulty in thermal control during poor weather. 3D foot space allows the foot to move more freely
TIPS FOR USE: In order to better utilize the warm function of the sleeping bag, it is recommended to unfold the sleeping bag the day before use to make the down fluffier, and then store the sleeping bag before departure to take it away. It is recommended to use the sleeping bag together with a Naturehike sleeping pad to maximize the warmth of the bag
