How do Milwaukee heated jackets work?
They're powered by an M12 REDLITHIUM battery (via a USB adapter) that drives carbon-fibre heating zones across the chest and back.
Is the battery included with Milwaukee heated workwear?
Some are sold as kits with a battery and adapter; others are bare garments - check each product and add an M12 battery kit if needed.
What size should I order?
They fit true to size with room for a base layer - size up if you'll wear it over heavy clothing.
