The clear Nalgene water bottle is perfect for all my travels. Mum active and concerned about ecology, not wishing to accumulate plastic bottles, its capacity is perfect and I can fill it anywhere. Very hygienic, it washes easily, including dishwasher and retains no odor or mold. Having started using a Gobilab during my pregnancy, I was disappointed because it quickly abyss, I had to exchange his cap with that of my husband (who never use it) because-he had started to crack (without passing through the dishwasher) and capacity less than 50 cl was not enough for me. The longer the Nalgene water bottle, beyond its qualities, of course, one-handed opening with the push button up, which is very convenient when you always have a stroller at the end of the arms :-)! Again, delivery by Amazon ran perfectly on time, no problem, without altering the product ... I am very satisfied, as with all commands I spend on Amazon :-)! I highly recommend this bottle I have chosen after having studied much!
