Nalgene OTG Tritan Bottle Features
The side has graduations in ounces and milliliters to help you keep track of your intake. The clear plastic also allows you to get a good view of what you are drinking.
The wide mouth of the bottle makes it easy to add ice cubes or powdered sports drink mix. It's dishwasher-safe.
The Nalgene OTG Tritan is made of clear, hard, impact-resistant Eastman Tritan plastic. Don't fear your Nalgene. It still has a 7 in the triangle on the bottom which denotes its recycling stream, but you can look for the BPA-free or Tritan designation.
The top of the OTG Tritan Bottle has a handy loop you can use to hook the bottle on a clip or hook, or dangle it from your finger. The bottle itself is a little too large for my small hand to grip comfortably. But I do not recommend carrying a water bottle in your hand for walks of more than a few minutes, as that can lead to repetitive stress injuries.
Do You Need a BPA-Free Water Bottle?
Many water bottles have always been BPA-free, as they are made of opaque or semi-opaque squeezable plastic rather than the rigid, clear polycarbonate. If your clear plastic water bottle has a 7 inside a triangle on the bottom, it might be polycarbonate, although it could still be BPA-free.
The 2008 version of the Nalgene OTG Tritan is BPA-free even though it has a numeral 7 inside the recycling triangle on the bottom of the bottle. Look for labeling on the tag that says it is made of Eastman Tritan plastic, which is manufactured without BPA.
