A mummy bag in two warmth ratings — pick your season. MJ300 for 3-season nights down to +4°C, MJ600 for deep winter to −12°C. Contoured to trap heat, compact enough to disappear into your pack.
Mummy shape isn't about looks — the contoured cut cuts the dead air your body has to heat, which is exactly why it stays warm when a rectangular bag would leave you shivering. Match the model to your coldest expected night, not your average one.
