The Nalgene Ultralight HDPE Wide Mouth bottle is very light (3.75 ounces), BPA free and sports the retro Nalgene logo of old. The wide mouth opening is compatible with many filters and accessories and makes cleaning or adding ice easy. The 63 mm loop top closure is leak proof and stays attached to the bottle.
Available in three colors, the translucent bottle has graduations on the side to help you gauge your intake. HDPE bottles are dishwasher safe (away from the heating element) and have a wide temperature tolerance. Made in the USA.
