Great for a morning out on your skis, the Sigg Metro Mug allows you to enjoy a hot cup of tea, coffee, or cocoa while exploring the winter wonderland. This insulated container keeps hot beverages warm for up to six hours and cold drinks cool for up to 12 hours.
Little Gem
I love this thing. It is the perfect size. I wanted a mug that fits in my water bottle holder on my bike that is totally sealed. I can commute with my cup of joe and it will still be warm by the time I get to the office.
excellent product
I was in a big hurry to get going on the many errands I had one morning so I took my second coffee to go in my metro mug. Well, once at the mall, what can I say, I spent a lot more time shopping than I intended to. But when I got back to my car (3 hours later), the coffee was still hot - not lukewarm and barely drinkable - HOT. I was surprised but grateful.
Perfect Size Travel Mug!
I got the 8.5 and it does a splendid job. Its not too much nor is it too little. Keeps hot drinks hot and cold drinks cold.
