[Mummy Shape for a Perfect Fit] The unique mummy shape is designed to fit snugly to your body's contours. This reduces wasted space inside the sleeping bag, preventing the spread of warm air caused by body heat and maximizing heat retention. The wide trapezoidal footbox design ensures a relaxed, comfortable sleep without any cramping around the feet.
Incredible Warmth: Filled with 95% goose down, swan feathers have long, thin filaments that intertwine in an intricate pattern, forming countless microscopic air pockets. These air pockets block out cold air from the outside and efficiently trap heat generated by the body. Compared to duck down insulation of the same weight, it offers superior insulation, providing consistent warmth even in extremely cold environments. Furthermore, goose down, despite its fine structure, possesses high elasticity and strength. This allows it to withstand repeated compression and expansion, retaining its shape even after extended use.
[3D Box Quilt Construction] Unlike traditional flat-fill methods, the lattice-like, closed-cell structure distributes the down evenly, preventing it from blowing out, shifting, or shifting. It conforms to the contours of your body without gaps, locking in your body heat while preventing cold air from entering. It minimizes heat loss through gaps around the shoulders and waist, allowing you to enjoy consistent warmth.
High-Performance Fabric: The sleeping bag's outer layer is made of durable 400T nylon, which is waterproof, windproof, and breathable. This prevents the down from escaping and protects the warm air inside the filling from condensation and moisture caused by rain. The inner layer is made of soft nylon, so it doesn't feel uncomfortable against the skin. It also has moderate breathability, preventing stuffiness even when sweating, maintaining a comfortable sleeping environment.
Lightweight and compact: The entire sleeping bag can be compressed and stored in its own storage bag, making it compact and easy to carry even on long hikes or camping trips.
