Spiritus The Muff Handwarmer

Keep Your Hands Warm. Keep Your Head in the Fight.

Spiritus Systems The MUFF Handwarmer

The MUFF is your cold-weather fallback—designed to give your hands a break between trigger pulls, gear checks, or comms adjustments without adding bulk to your kit. Developed in collaboration with the twisted minds at WRMFZY, this stowable sub-abdominal handwarmer brings compact utility to a brutally overlooked problem: frozen fingers.

Whether you’re rucking in sub-zero temps, standing a frigid watch, or just trying not to lose all sensation in your digits—The MUFF’s fleece-lined, compressible main compartment is your new best friend. And because every inch of real estate matters, it also packs a built-in gear pocket so you don’t have to give up mission storage for comfort.

Mount it to your plate carrier or wear it as a standalone with the included waist strap. Either way, your hands will thank you.

Note: No plate carrier, accessories, or attachments included. Includes handwarmer pouch and waist strap only.
