Abstract: An information handling system carrying soft case includes fabric forming an interior, such as within a backpack or briefcase form factor, and a sleeve disposed in the interior and sized to contain a portable information handling system housing. The sleeve has a rectangular cover of sufficient area to hold a portable information handling system and coupled to the fabric interior on three sides with an open mesh material at an interior of the sleeve and a corrugated foam at an exterior of the sleeve. The open mesh material has plural evenly spaced openings that pass air in the event of thermal heating in the sleeve and that pass particles out of the sleeve and away from the information handling system.
