Soft Comfort Lining:
The inner lining features a soft comfort polyester material that enhances your sleeping experience by providing a smooth and cozy surface against your skin, helping ensure restful sleep in the outdoors.

Durable Outer Fabric:

Mummy-Style Shape:
The ergonomic mummy design helps trap body heat more efficiently than rectangular sleeping bags, reducing excess space and improving thermal performance. It also contributes to a smaller packed size for enhanced portability.

Usage Tips

Layer Appropriately for Cooler Nights:
For lower temperature conditions near the 2°C mark, wear thermal base layers or use an insulated sleeping mat to enhance warmth and comfort.

Store Loosely When Not in Use:
To maintain loft and insulation efficiency, store the sleeping bag uncompressed when not in use.
