Ever walk into Starbucks and ask for a cup of water? I do it all the time cause their water tastes so good. There have been plenty of theories of why their (free) water is so good but it comes down to the filters they use. Simply put its much better than tap water.
Luckily, with Camelbak Groove Insulated Water Bottles you can drink water straight from the tap because it has a filter inside the water bottle. Just to be clear I am not saying this filter will make tap water taste like Starbucks water. Nonetheless, it does make tap water taste pretty good.
These reusable water bottles also keep your water colder longer because they are insulated as well. Basically, these water bottles from Camelbak combine all the best features of water bottles into one.
