I have 5 of these water bottles! lol and one of them is a hello kitty one :D I love them. They come in soo many different styles and they're so much better for your body. Plus they last alot longer than the plastic ones and are environmentally friendly. If you have kids, they also make little 4 oz sigg bottles with kids designs on them! they're waaay cute! My husband used to work for the company and it really amazed me how many different styles they have. You could literally have one for every mood and outfit :P seriously, i would invest in one though, because beside the awesome style, the water tastes so good and so cold for so much longer :)

I completely ADORE my Sigg. It goes everywhere with me. Like the last reviewer, I also bought mine when Nalgenes were pulled and I don't think I will ever regret this purchase. Sure, the bottles are pricey...but they have designs to suit pretty much anyones taste - from conservative to ultra funky. The contents never taste stale and in the month I've had it, it hasn't taken on any odd smells. I resisted the move to a metal bottle for a long time and now I regret not changing over sooner.

I bought both myself and my hunny 1 litre bottles. He loves his just as much as i love mine...and even said "Don't expect me to have just one of these" ... I fully anticipate myself buying a second one shortly to keep at the office.

I love my Sigg water bottle! I bought it when manufacturers decided to pull all Nalgene water bottles from the shelves from the whole controversy of the chemical bisphenol. Aside from all the cute designs you get to choose from, it really is a sturdy water bottle! And most importantly it doesn't leak at all! I've left soda in there for several days and it will still remain as carbonated the day I poured it in. The water doesn't taste stale or plastic even after it's left in there for several days. I used to have that problem with regular Nalgene water bottles. All the materials used to make the Sigg bottle are environmentally and human health friendly. I would definitely recommend this as the alternative to the other water bottles. Unfortunatlely they are hard to find in Toronto, so you either have to buy them online or check their website for the locations that are selling them.
