This bottle is made of grade pc and silicone and really good quality.At the bottom of the bottle there is a lemon/ citrus fruit squeezer which is so healthy and a alternative to get you to drink fruited water.I for one don't drink enough water and this bottle will encourage me to start doing so.The way to do this is unscrew the bottom part and turn it upside down and squeeze the citrus fruit out and then screw back on and fill water from the top part.There is a loop at the top for ease of carrying around with you.Good bottle to purchase.
