All you love is the Sacred design of the traditional Nalgene water bottle, and one of the reasons for the images, narrow-mouth Nalgene Tritan. Made of super-tough Eastman Tritan polycarbonate, Tritan is preserved by minimizing the likelihood of most nalgenes as roomy as the interior of the narrower loop at the top of the cap that doesnt spill out. In addition, the bottles BPA free construction is impact-, odor and stain resistant, and it can withstand a variety of uses from -40 to 212 degrees Fahrenheit and will not be applied in the last year. The bottle also features printed sides for easy measuring water quantities. Recommended for the ultimate adventure, Tritan bottles come in a variety of Vivacious colors.
