For those who prefer a roomy bottle with a smaller opening, we offer our narrow-mouth loop-top Tritan bottle. It offers all the same advantages as our wide-mouth, with a top that minimizes the chance of spills and a cap that never gets lost.
 Made of super-tough Eastman Tritan polycarbonate, the Tritan offers the same roomy interior as most Nalgenes, but with a narrow loop top that minimizes the chance of spills and a cap that never gets lost. In addition, the bottle's BPA-free construction is impact-, odor-, and stain-resistant, helping it withstand a wide range of temperatures (from -40 to 212 degrees F) and last for years. Finally, the bottle includes printed graduations on the side, making it easy measure water quantities. Recommended for extreme adventures, the Tritan bottle is available in a variety of vivacious colors.
