noe, no problem for sharing. Think all mummies are here to share.
Wan wan, i have bought the nivpak bag, its slightly heavier than the popkids one ($69.90) i checked out yesterday, went to the fair and great to find out that they are selling the bag at $39.95. After chatting with the sales person who show me how their bags shoulder straps are made which was better than some brand. Even my petite son carry also just nice.
I also went to check out one of the brand sold by robinson, i forgot the brand, that one, selling about $89.90 but haven;t put anything inside already can feel the weight, I thought the interior bands design in cross like our luggage bag was better than the nivpak straight across ones though. But comparing, i think its worth to get this nivpak.
The popkids ones are wrapped in plastic bag and no one to assist me so can't see the inside. can't compare much but this one comes with a open top concept, got good got bad.
