This has been out for like 3 or 4 years already, lol so it’s nothing new, but Amy just started using them when we were playing tennis in Central Park, and let me tell ya, I wish I had them!! It’s the best designed water bottle for any sports activities. There’s a special top that locks in securely, unlike the other “sports bottles” that basically just has a little snout that you pull up or down, not very secure. Plus the Evian “Action” water bottle has a little hoop on top so you can hook it to your backpack or belt or whatever when you go do your sporty things whatever that is. Now all I need is invent a hook on my iPod then my sporting accessories will be complete… lol, it only gets a “kinda” HOT because I probably would’ve liked the to be a little skinnier, but Fat Bottles need lovin’ too right?? lol
