Today was an extra special day, because I forked up to get myself another Sigg. The ugly one to the left, I bought on sale, but it keeps my drinks extra hot or cold for hours at a time. So regardless of the color, I still rock it. My latest addition, will be used for the gym, and also for my purse.
I had another reusable cup/bottle thing that has a cute Hello Kitty design on it, but I just found out that the stainless steel inside, is leeching a nasty metal flavor into my water. All SIGG bottles have a special coating inside their bottles, so it will not react to acidic liquids, nor will it leave a weird metal taste in your beverage. I have a giant 1 liter bottle for our bike rides, but now new Sigg will be my everyday bottle.
