hayaku wrote a review of Stanley Outdoor Drink-Thru Bottle - 16oz on November 4, 2008
This thing is built well. As a coffee cup snob, I've gone through my share of packable bottles. While my previous one from Thermos had a cap that enclosed the drinking lip, it was too small, and not built as sturdy. 16oz is perfect and the build quality is superb. In addition, the cap can be completely disassembled for easily cleaning. As the poster above mentioned, thermally, its working very well. I've tried ice water in it so so far, and after about 3 hours, my ice cubes are only a slightly melted. If you need a secure closing commuter cup and willing to pay a few extra dollars for quality. I highly reccomend this cup. The unique copper I got is also a plus. On a side note, the Stanley logo is a sticker which was easy to peel off.
