Sigg bottle!! This is actually the second Sigg bottle I've owned, but earlier this year I left a Vega Shake in my former Sigg and then it rolled under the car seat and let's just say I haven't fully finished cleaning it out yet.
At any rate, I was in Central New York earlier this year and I had to visit Wegmans. While I was there, I figured I might as well get myself a new water bottle for travel. I hesitate to admit that it probably took me between 10-15 minutes of looking through all of the design options on the Sigg shelves at Wegmans before I could choose this winner, but I did. Flowers? Technical designs? Doodles? Ultimately, this werewolf won out because it is pretty awesome. I like these bottles because they are the perfect size and don't have a "sport" top which I find pretty useless with a bottle that you can't squeeze and also hard to clean (see above for a hint at my issues with cleaning). There are a lot of debates over which kinds of reusable bottles are the healthiest to drink from, but I feel pretty good about the Sigg and I like that they must be invested in supporting design by offering a huge variety of styles to choose from. So, Sigg gets my vote.
