The MUFF is a stowable, sub-abdominal handwarmer designed in collaboration with Spiritus' friends over at WRMFZY. It was built to remedy to the pain of operating in cold temperatures and having nowhere for hands to retreat to in between fine motor skill tasks. Unlike much bulkier offerings, The MUFF is designed to be compact and stay out of your way when not in use. It also features a multi-purpose gear pocket, so the wearer does not have to sacrifice as much valuable storage real estate on the body in exchange for maintaining finger dexterity in the winter. The MUFF can be mounted to the bottom of a Spiritus Systems plate carrier or chest rig system using the integrated hook & Mfg: Spiritus Systems
