GREAT BOTTLE! The lock system on the lid is really useful while traveling and racing. The bottle is also see through which is a real game changer for my racing. Now when racing I can see when it’s time to switch for a refill. It’s really lightweight, which is a great way to shave off those extra grams. The quote (STRENGH TO GO FUTHER) is something really special. It’s a one of a kind brand, that would put in the extra effort for the athlete to have extra motivation in their hand.
