sleeping bag 3d model

A long, narrow survival sleeping bag standing upright, charcoal black, dark colored, with a smooth tapered profile that gradually narrows toward the feet, has a zipper to open and close the bag, The hood is rounded and sculpted, rising gently at the top with a structured rim. A visible side zipper runs from the midsection up toward the hood, allowing the top flap to open slightly. The outer shell has fine horizontal quilted baffles running across the body, giving a padded segmented texture. The interior shows a dark fabric lining with a subtle sheen, and a glimpse of a silver colored heat-reflective thermal layer inside of the bag. The overall design feels practical, expedition-ready, and built for harsh wilderness survival.
