The Primitive Warm Sun Adult Sleeping Bag: Extra-Thickened Winter Comfort

Experience the ultimate outdoor rest with The Primitive Warm Sun Sleeping Bag. Designed for those who refuse to compromise on warmth, this all-season sleeping bag is engineered with a specialized three-layer temperature-locking system. Whether you are trekking through a chilly autumn forest or camping in the heart of winter, this thickened, cold-proof bag provides the cozy security of a home quilt in the rugged outdoors.

Key Benefits

Advanced 3-Layer Insulation:** Featuring a 210T Pongee outer shell, high-quality hollow cotton filling, and a 190T Pongee lining, this bag creates a windproof barrier that traps heat effectively while remaining breathable.

Superior Hollow Cotton Filling:** Unlike standard imitation down, our high-loft hollow cotton offers better thermal retention and moisture-wicking properties, keeping you dry and warm even in damp conditions.

Oversized for Maximum Mobility:** With an extended length of 230cm and a widened width of 85cm, this bag offers significantly more room than standard models, allowing you to turn and move freely without feeling restricted.

Modular Splicing Design:** The intelligent side-zipper system allows you to connect two bags (left and right versions) to create a spacious double sleeping bag for couples.

Dual-End Temperature Control:** A dedicated bottom zipper allows for independent foot ventilation. If you feel too warm, simply unzip the bottom to let your feet breathe without exposing your torso to the cold.

Versatile Utility:** The full-perimeter zipper allows the bag to be completely unfolded, transforming it into a large, soft quilt for indoor use or a clean ground mat for picnics.
