The Katadyn MyBottle Drinking Bottle is ideal for work, leisure activities or sport. The ergonomically shaped drinking spout, with soft mouthpiece, is easy to fold in and out, doesn't leak, and the straw makes it possible to drink without tilting the bottle. The carry loop on the lid makes the MyBottle convenient to carry or hook to your backpack. The MyBottle is BPA-free, taste-free and dishwasher safe. With the Katadyn ViruPur, it can be easily upgraded to a water purifier.
