Storm Shield

Slim and provided with a handy zip-up bag, the Storm certainly looks the part. The push-button pourer worked well although, measuring only 50mm in diameter, the neck was pretty much for drinks and smooth soups only. There's only one cup, which is metal and has no handle, so if the liquid is too hot it can be uncomfortable to hold. Not that this would be a problem for very long, however, as the Storm's heat retention was the poorest on test.
