This modular system finally solves the restless sleeper’s dilemma by anchoring your bag directly to your pad. While the multi-layer design adds a bit of bulk compared to a minimalist mummy bag, the trade-off is unmatched versatility that lets you customize your warmth across three distinct seasons.
