Most heated base layers can be machine-washed on a gentle cycle after removing the batteries and controllers. Always use a mesh laundry bag, cold water, and mild detergent. Never use fabric softener or bleach. Do not tumble dry—air dry only. Check the manufacturer's specific care instructions, as some models require hand washing.
