For wipes I just bring my cloth wipes and an empty peri-bottle, I fill up the bottle after we pass through security or in the plane and then just use that as we do at home (spray wipe or baby) and toss the wet wipe in w / dirty cloth diaper in wetbag. (clothdiaperaddiction.com)
I have been roating two of these pail liners as hanging wetbags for daily use for one year. (thirstiesbaby.com)
I would love to see nursing products and a large wetbag with handles and elastic instead of a drawstring. (thirstiesbaby.com)
