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.
