Water bottle cover Size: Approximately 8cm in diameter x 24cm in height Strap length is adjustable This is a water bottle cover that came with a stainless steel water bottle purchased several years ago. The water bottle is a NEW Energy Charger Direct Bottle 800ml. I think it can be used with other water bottles if the size fits. I only used the water bottle and kept this cover stored without ever using it. When shipping, I plan to fold the bottom flat to fit within a 3cm thickness, so there may be some loss of shape or folding marks. Please read the profile before purchasing.
