We had two trips planned this spring/summer, and these bottles made traveling with an infant just a little bit easier! It was so useful to be able to toss the liners in the garbage and wipe down the top with a sanitizing wipe (marketed for pacifiers and toys) we weren�t constantly having to search for a place to wash bottles and missing out on important family fun activities. It also cut down on the items we had to pack, because we only brought two bottles with us for a week long trip!
The waste of disposable liners isn�t ideal for daily use, but it was fantastic for on the go travel (car, plane, out and about, boat).
