The Naturehike Penguin Cotton Sleeping Bag is engineered for serious cold-weather camping. Available in two fill densities — P300 (300g/m²) and P400 (400g/m²) — it uses a down-cotton mixture fill (cotton base, down top layer) that delivers exceptional warmth-to-weight performance. The polyester pongee outer and washed cotton lining create a durable, skin-friendly shell that holds up across seasons.
Rated temperatures are precise and tested: P300 is comfortable to 6°C, with a limit of 1°C and extreme rating of -13°C. P400 pushes further — comfortable to 1°C, limit -4°C, extreme -18°C. At (190+30) × 80 cm, the extended footbox accommodates adults up to 1.8 m with room to spare.
