Engineered for those who toss and turn, this bag features a unique shape that moves with you rather than restricting you. It balances warmth and weight by mapping synthetic insulation in high-pressure areas while keeping premium down where it counts most.

This mummy bag solves the age-old frustration of sliding off your mat by integrating a dedicated sleeve for your sleeping pad. While the slim, heat-trapping silhouette sacrifices a bit of wiggle room, it creates a secure, efficient sleep system that keeps you warm and centered all night long.

This is the rare sleeping bag that actually adapts to your sleep style, shifting from a roomy, rectangular shape to a heat-trapping mummy configuration on demand. You sacrifice a bit of weight for that modularity, but the integrated arm holes and damp-resistant down make it an incredibly versatile shelter for unpredictable shoulder seasons.
