Attaches easily to the main food carrying bag. Has a mechanism at the top to narrow the top so the bottle doesn't fall out. Keeps the bottle cold many hours.
Perfect match for my lunch bag, easily accommodated my thermal mug or 1-1/2 liter water bottle. 👍
Excellent. Well built and sturdy. Holds a 32oz insulated bottle. The extra insulation in the holder keeps ice water cold much longer than just the bottle itself even when stored in my motorcycle saddlebag all day
