Thing is though, if you take it out of your pocket - say by the side of a steaming river at dusk in November or in a snow-covered, wind-blown field - and use it for any length of time to try and coax some feeling back into your frozen, insensible fingers - then it cools down pretty damn quick. It keeps your pocket toasty as hell - and I'm not knocking that; having even one warm pocket on a winter's day is a happy thing - as any fule kno - but the times when I've wanted it to bring my cold, wet, frozen fingers back to life, my main memory is wishing the damn thing was warmer. Take it out of your pocket in the cold - it goes cold.
I've never tried those burning charcoal stick hand-warmer thingies you can get - does anyone out there know if they're better than these Peacock jobbies?
I suppose that there's a question to be asked about their respective carbon footprints? Well, I haven't got a clue about the answer to that question. Any ideas?
Were Tuvalu not in danger of being submerged I suppose the ideal cold weather hunting outfit might be something like a white Ghille suit plus a patio space heater. Very cosy. One or two questions regarding mobility do rather raise themselves, mind.
