I take this bottle with me every time I go to the gym and its’ great for many reasons. Drinking cold water not only boosts your immune system, it helps you burn more calories. I’m a high performing athlete and every advantage I can get over my opponents allows me to take my game to the next level and potentially score more goals.Why this is the perfect gym bottle?-It keeps your water cold at the gym the entire time-For soccer games, I always have ice water. HUGE PLUS-Easy handle for long journeys. I uses The Coldest Water Sports Straw cap for short journeys and biking-Its’ a lot more durable and higher quality than I thought it was-It can float in my pool while I’m swimming for easy accessThank you for creating such a great gym bottle!
