• Premium 750+ Fill Power Goose Down Filled with high-quality 90% goose down and certified by RDS (Responsible Down Standard), ensuring excellent warmth-to-weight ratio and ethical sourcing. Each bag includes a traceable barcode to verify down origin.

• Comfortable Temperature Range Engineered for mild conditions, with a comfort range of 10.5–19°C (50.9–66.2°F). Ideal for spring, summer, and early autumn camping, providing just the right amount of warmth without overheating.

• 3-in-1 Versatility Easily converts between three modes:  Sleeping Bag Mode  for full coverage,  Blanket Mode  for relaxed lounging, and  Shawl Mode  for hands-free wear around camp. It can also be used as a warm liner inside another sleeping bag for extra insulation.

• Durable & Thoughtful Details Built with a water-repellent 10D nylon shell that is PFAS-free and breathable.
