Review on Bike Bottle Holder Bag With Phone Storage & Insulation For Touring & Commuting by Dave Albright

Has the title states, this product works as intended, however keep in mind that it weighs down and sags depending on the size of your water bottle. I have a 24 oz dual walled aluminum water bottle and this pouch cannot withstand the weight of it when it is full of water. Although it does stay on quite precariously, it sags significantly and appears as though it will detach from the bike at any minute. I have seen many people use nalgene bottles which are extremely lightweight, so it may work better in these situations.
