Naturehike Mujin™ Pro Synthetic Mummy Sleeping Bag utilizes Sundounce™ Gold-label fill, a high-performance synthetic insulation, paired with an openable foot box and soft-touch lining for versatile comfort in the backcountry.

Key Features:

  • Sundounce™ Gold-Label Fill
    Sundounce™ is a high-performance synthetic insulation with a bionic down-like structure. Microporous fibers trap heat, while far-infrared technology boosts warmth retention—delivering down-like warmth with a superior warmth-to-weight ratio for a lighter, more compact bag.
  • Openable Foot Box Design
    The foot section unzips independently, allowing you to stick your feet out, move freely, or step in and out without fully exiting the bag.
  • Lightweight & Packable: Weighing approximately 670g / 1.48 lbs (M/75*190cm), the bag compresses down to the size of a 1L water bottle, making it easy to carry and store in tight backpack spaces.
  • Antibacterial & Skin-Friendly: The soft fabric offers over 90% antibacterial efficacy, providing a comfortable and hygienic sleep surface for sensitive skin.
  • Eco-Conscious Materials: The face fabric is made from GRS-certified recycled yarns, ensuring the materials meet globally recognized standards for sustainability. A PFC-free, skin-friendly water-repellent treatment provides reliable weather protection without the use of harmful fluorocarbons—better for you and the environment.
