Nalgene is an American manufacturer of sports bottles for everyday use with a tradition stretching back to 1949. You can carry them to work, on a trip with the family, and even when hiking in the mountains.
The key to their success is the recyclable and highly durable tritan plastic found in most Nalgene bottles. In addition, it contains no BPA or other toxic substances. This will be especially welcomed by parents who are looking for health-friendly Nalgene baby bottles.
Nalgene cycling bottles are also very popular. With these, all you have to do is pull it out of the bike mount, pop off the cap and squeeze the bottle. Nalgene OTFs are similarly easy to use, and you only need one finger to open them.
