I absolutely love the Nalgene-Tritan Silo bottle!!! I really like the optical measurements of the amount of water, and I love how the uncharted logo boldly stands out. I’m very proud to show off this brand because of how well their products are made. The lid and bottle have an excellent ergonomic design, particularly how well I can grip it and how the lid latches on to the bottle. This is a great bottle to have and I definitely recommend it.
