The beauty of purchasing water bottles from Camelbak is the ability to get replacement spare parts when you need them. We are an official Australian stockist of Camelbak and have been since 2009. If you need a spare lid, a replacement lid, a bite valve or more, we have your covered. If you're not sure which spare part you need, don't hesitate to send us a photograph of your bottle and we will ensure you're purchasing the correct item. Over the years there have been some upgrades and some of the very old bottle lids may not have suitable bite valves anymore, but the threads for the lids remain the same and you should be able to purchase a new lid.
