Ok... So, I would never say anything bad about my bag people-especially my customer service rep Johnathan.
But this bag was not venting. So I called up Johnathan and told him my issue: I got 20 of the vented bags and it seems like they aren't doing their job. Is there some way to prep it?
He assured me I was doing the right thing and they are ready-to-wear right out of the box. He offered a suggestion as to why my bags are still puffing with air. He said if you have a large puff of air at one time, it could take minutes for it to filter out...
Ok, so the product is not faulty. Apparently I am just unusually gassy... ALL THE TIME!! Must be all those burritos. :)
