Hi! Having just spent a freezing day with the heating broken at work, I am in the market for a truly warm, thermal-type compact travel blanket that I can throw on in the office (I run a small branch library in a 'temporary' building that over the last thirty years has become permanent, so insulation is not great, though the heaters are fine when they work!) or in the car. I am in the UK, so ideally am looking for something I can get over here. I was wondering if anyone has any recommendations?
