Bests & Worsts Reviews from Amazon

I was searching on the internet for a water bottle for hot yoga and read many reviews which lead me to The Coldest Water bottle. Originally, I was leading towards the Hydro Flask, but was uncertain if their sport cap would leak, so I went with The Coldest Water bottle and am very pleased with my purchase. I fill the bottle with ice cubes to the top, then fill it with water the night before I go to work, leave the bottle in my car, take it to hot yoga (100+ degree for over an hour) at night and the next morning, ice still remains. Mater of fact, I did this on Wednesday night, had it at yoga on Thursday evening and ice was still there on Saturday morning, granted I did not refill it much with water. Although, the colors of bottles available are boring the sport caps does not leak at all, even when the bottle is left on its side. Their cleaning brush also makes cleaning the bottle easy. Definitively a recommended purchased.
