This is a Canadian company that carries one of..NO sorry the best Hot/Cold stainless steel bottles ever!! Their bottles are now triple insulated, at the time I purchased mine they were double insulated I can't even imagine it getting any better. I was convinced this bottle would do its job at keeping temperatures for hours after being shown a sample of both hot/cold temperatures being kept at the time of purchase. I bought my bottle 3 years ago at the CNE ( in Toronto ) it was later in the evening when I bought it and the lady selling them was showing customers how the ice in one bottle had remained solid and had been there since morning and while another bottle held hot water which when she opened still released some steam, this was at about 7pm. I couldn't walk away knowing this was not only an awesome bottle for water or anything else I'd want to drink cold but I could also use it for coffee or tea. So now it was time to decide which colour I wanted, and with a few to choose it took me a min or 5 :) I finally decided on pink and then was told the bottle came with TEA/ICE strainers INCLUDED this was a bonus as this has really come in good use. These bottles are made of stainless steel and are very safe to use, the company has a website so if you've been looking for that PERFECT bottle that will stand behind its claims and will last you a long time visit their website @ www.greensyourcolour.com they also carry many cool accessories for your bottle like different lids such as coffee lids, sports lids, straw lids so now you've got one bottle with endless uses.
I must also mention they also carry a baby bottle sets made of stainless steel as well but come with transitional lids so you would just be changing the lid as your chid grows. very cool!!
