Enclosed Heat for Both Hands

WarmHeart combines an insulated hand muff with heating areas across both sides, creating one shared warm space for stationary cold-weather use.

Front-and-Back Heating

Heating areas are positioned across both sides of the muff so the front and back of both hands receive heat inside the same insulated compartment. Elasticized openings help reduce heat loss while allowing quick hand access.

5V Power Removable battery system
5000mAh 18.5Wh lithium-polymer battery
Double-Sided Heat Heating areas on both sides of the muff

Three Heat Levels

Select the output that suits the conditions instead of running the highest setting throughout every use.

Low

Lower output for milder cold.

Medium

Balanced heat for general outdoor use.

High

Maximum available output for colder periods.

Temperature and runtime vary with the selected level, ambient conditions, battery charge and battery age.

DWR Polyester Shell

Helps shed light moisture, but it does not replace a waterproof membrane or protection from prolonged rain and soaking.

Soft Insulated Interior

A soft fleece lining and insulating fill retain warmth around both hands inside the enclosed space.

Waist-Worn Fit

The adjustable belt positions the muff at the front of the body for quick access while standing or sitting.

Small-Item Pocket

The front zip pocket holds compact essentials such as a phone, keys or cards rather than bulky equipment.

Best Used While Stationary

WarmHeart suits sidelines, outdoor events, hunting blinds, camping stops and cold-weather work breaks when both hands can rest inside the muff.

Keep Your Hands Available

Do not keep both hands inside the muff while driving, cycling, operating equipment or moving where balance and hand control are required.
