If you're a wheelchair user or if you suffer from bad circulation it's easy to get very cold very quickly, but it's not so easy to warm up again. This heated jacket equips you for the cold, so you can get on with your day a usual. It spreads warmth across your back and chest and the heated element at the collar is in just the right place to keep chilly breezes at bay. The rechargeable batteries keep going for up to ten hours, depending on the conditions outside. If you're likely to be out all day it's a good idea to buy the extra battery kit. That way you can keep a couple of spares with you to make sure that your jacket stays beautifully warm all day long.
