Under Jacket USB Powered Warmer
The HEATSYNC VITAL is an under-the-jacket heating system designed to keep you warm in the harshest conditions. The harness design is one-size-fits all, so you can keep one for every member of the family who needs to take the edge off an especially icy winter day. Ideal for cold weather situations where movement or activity is low, or in dire situations where the user has become trapped or lost, HEATSYNC VITAL rests against a shirt or base-layer and is powered by any BRUNTON 5V/2.1AMP USB power bank (not included).
