This sports water bottle is perfect for taking with me to yoga class, the gym, school, and work. It holds 1 Liter of water, which is perfect, and helps me make sure I drink the full recommended daily amount of water, no matter where I go. The adjustable shoulder strap makes for easy, hands free carrying, and I love the built in straw, which makes it quick and convenient to grab a quick sip or two without missing a beat or having to slow down my heart rate to rehydrate. I highly recommend it to anyone who is health conscious and on the go most of the time.
