Nalgene was one of the companies hardest hit by fears about BPA in polycarbonate bottles, as they have long made their excellent line of outdoor bottles of the clear plastic polycarbonate Lexan polymer. They swung into action to replace Lexan with Eastman Tritan copolyester, which is BPA-free.

Nalgene OTG Tritan Bottle Features

The OTG Tritan Bottle has a flip cap to close off the mouthpiece. I didn't find it as easy to open as I would like, which is why I give it less than 5 stars. But the mouthpiece is easy to drink from. You can really gulp down the water versus being stuck with the slow flow that you get from squeezable sports bottles.

The side of the bottle has gradations in ounces and milliliters to help you keep track of your water intake. The clear plastic also allows you to get a good view of what you are drinking and the level of water in the bottle. The markings can help you ensure you are drinking enough to replenish the fluids you lose during a long workout.

The wide mouth of the bottle makes it easy to add ice cubes or powdered sports drink mix. That's important for me as I like cold water. It is also easier to refill on the go at a water fountain or from a tap. The bottle is dishwasher-safe for cleaning.

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 walkers are concerned over reports that damaged clear polycarbonate water bottles might leach bisphenol A (BPA) into the water. While many research studies show the polycarbonate bottles to be safe, manufacturers are moving swiftly to provide BPA-free versions.

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.

As of 2008, 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.
