Airflow2×active fans
A dual-fan ventilation path moves air through the laptop compartment while the system is running.
SessionKeep awakeoptional closed-lid mode
MoonStat holds a macOS power assertion, with separate controls for display sleep and closed-lid work.
Sampling60 seclocal thermal history
Battery-sensor temperature and Apple’s system thermal state are recorded locally once per minute.
Safety cutoff45°Cadjustable default
The session can stop at the configured battery-temperature limit or a serious or critical thermal state.
OuterTyvekultralight shell
A compact, low-mass exterior gives the bag its paper-like texture and distinctive technical profile.
CoreRipstopnylon reinforcement
A reinforced grid-weave structure supports the high-use areas without turning the bag into a heavy case.
Background work · Active airflow
Pack up before it's finished.
Don't wait for an upload, render, export, or agent task to complete. Start a MoonStat session, switch on both backpack fans, and move while the Mac continues working in the background—awake, ventilated, and thermally supervised.
Two integrated fans ventilate the laptop compartment while Tyvek and ripstop nylon keep the carry system compact and light.
MoonStat records the battery sensor and Apple thermal state locally, then ends the session at the configured safety limit.
Sensor note · MoonStat reads the MacBook battery sensor and Apple's qualitative system thermal state—not CPU-core temperature. Both fans must be running and all MacBook vents must remain unobstructed during closed-lid use.
Dual active cooling
Two integrated fans are positioned to move air through the laptop compartment during long sessions.
Ultralight build
A Tyvek shell keeps the form light, while ripstop nylon reinforces the structure for everyday movement.
Compact profile
A focused silhouette for a laptop and daily essentials, without the bulk of a conventional technical pack.
Material study
Paper-light.
Built to move.
Tyvek
Distinctive texture and an exceptionally light hand.
Ripstop nylon
Lightweight reinforcement where the bag needs added resilience.
Active airflow
Dual fan grilles make the cooling system visible and direct.
Keep the fan intakes and the MacBook's vents unobstructed. MoonStat can monitor battery temperature and Apple's thermal state, but physical testing remains essential for every supported MacBook configuration.
