The truth is this is a knock off of the beautifully made one on etsy.
It allows me to keep drinks in the insulated back for traveling. Very easy to install. After letting it off gas for a week, i notice no more potent smell.
The bag is very flimsy. After one week of carrying gum, crackers, and five mini water bottles, it continues to tear and fall apart. The zipper is super flimsy and gets caught on the nylon dangling strings.
