There are two basic types of collapsible water bottles that are great for runners: the smaller flask type, with a handheld carrier (such as Salomon Active Handheld), and the larger type, which can be rolled up and stored in a hydration vest or clip Hang on a belt or backpack (such as Vapur Element). The former is ideal when you really want to drink while running; the latter is more suitable for traveling or hiking-unless you run with a backpack, vest or jacket that can be stored.

Please note that the biggest complaint of all collapsible bottles is that they wear and leak over time, whether it comes from the soft bottle material itself or the valve. If you start using a leaky model, be sure to contact the manufacturer-the function of the collapsible bottle valve and the ordinary water bottle should be no different.
