Plenty of water without unnecessary bulk. The slim reservoir sits close to your back and fits in many trail vests and backpacks. This makes it particularly suitable for long trail runs, ultras, and mountain treks where you spend extended periods between water stations.
Refilling is easy on the go. The wide opening makes filling and cleaning easy, while the hose can be disconnected without the reservoir immediately emptying. Especially at aid stations or quick stops, you notice that you don't have to fiddle with your hydration system as much.
Drinking remains practical while running. The self-sealing drinking valve helps limit leaks, and the reservoir can be turned inside out after use to dry better. However, check beforehand whether your vest has sufficient space and a suitable mount for a reservoir.
Choose these for carrying a lot of water on your back. For short runs or quick access to various drinks, soft flasks are often more convenient.
