This is a soft case for bottles that can be easily attached to waist bags and backpacks. The mesh bottom allows condensation from the bottle to escape. It is lightweight because it does not use insulation, and it can be folded up small. It is the perfect size for a 500ml bottle. * Depending on the shape of the bottle, it may not be possible to store it.
