great item

they arrived quickly in minumul packaging.
easy to understand instructions and was up and running quickly.
the fit is good for size and id recommend to get the closest fit, no need to size up as this needs to feel close to the body for max effect.
This gives good gentle heat in parts where you would fell the cold the most, my son is wearing whilst riding  his motorbike in winter.
only downside is the battery doesnt last as long as stated so if wanting to get warmth from this thoughout a day it may struggle to do this.
would recommend as its a nice well made product and it does do what it states.
