I have had no problems with the zippers. After I read your question I grabbed my Fuego and zipped/unzipped the two main compartments several times trying to figure out what the fuss is all about, but I just can't find anything wrong with them. Maybe my pack is newer (I've had it for two months) than the other packs being reviewed here. But I would say that it is definitely NOT a big deal. I think you will LOVE this pack.
