The problem with them usually is that they don't heat too much and still consume the batteries very fast.

Try if you can find chemical heating pads somewhere. The are small fabric "pillows" filled with some kind of an iron compound. Once you unwrap them and they get in contact with air, they get surprisingly warm and stay that way for hours. There are at least two sizes, one to put in the boots and one for gloves. They have saved my day on more than one occasion 🙂

Many thanks for quick reply.  You are certainly in the right country to know about these things.

I haven't had any of these for a long time, but I think these are just the pads I've used in the past:

Why "Off Topic"? It's Wednesday, isn't it? 😕

P.S.: I'll be late tonight again, I'm going to a concert... See you later!

Thanks for additional info'.  I've now ordered from Amazon.  We head for the Alps early next year & my dear wife really suffers with cold hands so, hopefully, these will solve the problem.

Thanks to everyone who responded!

If you're going by plane, it might be a good idea to check in advance with the airline where and how to pack these, the new safety regulations might have something to say about them...

Have a nice trip! I might be there myself again next March, hopefully with better clothing and winter tyres 😂
