Ultralight and leakproof, made in the USA
For those who prefer a roomy, lightweight bottle with a smaller opening, Nalgene offers the Poly Narrow-Mouth Loop Top Bottle. It offers all the same advantages as the wide-mouth, with a top that minimizes the chance of spills and a cap that never gets lost. Printed graduations for easy measuring. Available in 16 and 32 fl. oz sizes.
