Don't let effects of dehydration - like headache, blurred vision, irritability, and fatigue - get in the way of being the courageous, empowered, compassionate one step ahead nurse that you are. Water infused with fruit helps with detoxification, energy and hydration - and tastes yummy! The lid on this drinkware is threaded for a tight seal and has a flip top covering the straw outlet (sturdy acrylic straw included). High-quality BPA-free acrylic. The possibilities for infusion combos are endless....but our fave is cucumber and mint leaves.
