I always carry water with me and am a fan of the 32 ounce Nalgene bottles. I freeze 16 ounces of water the night before and fill up the other half with water when I go in the morning. I didn't like how much the bottle sweated as it dripped all over my desk so I bought it mainly to prevent condensation from getting all over my documents. I took the bottle to work today (half frozen as usual) and got home with about 6 ounces of ice left in the bottle. There has never been ice. Not only did I survive a work day, but I walked home (about a mile) in 85 degree heat and still had ice cream. I need to start freezing 8 ounces instead of 16 because it insulates so effectively. There is also no condensation. It seemed a bit pricey but I'm glad I spent the money.
