Finding the right hydration system for you can be a bit of a dating game: Between handheld bottles, belts, and vests, there are plenty of options—but depending on how, when, and where you run, finding the one that works best for you can take some trial and error.


How to Choose the Right Hydration System for You

Picking the right hydration system is a personal preference, but it’s best to think about the type of run you generally do or are planning on doing. If trail runs are your jam, a bigger pack could be the solution, whereas shorter runs call for a handheld bottle. Of course, if you are a runner who hits up different trails and terrain, you might want a few options handy. Here is a rundown of the three main tops:


  • Pros: Distributes weight across shoulders, can carry a lot more than just water, and usually has larger reservoirs, often two, with the option of holding two types of liquid.
  • Cons: More straps mean more areas of irritation, a larger bag can create more heat against your body, and reservoirs are harder to clean.

Belt Packs

  • Pros: Keeps arms free, can hold more water but won’t put pressure on your back, and convenient for securing other essentials like money, keys, and lip balm.
  • Cons: Smaller with limited space for other essentials, bouncing can become an annoyance and not as effortless or breezy to get a sip.

Handheld Flask

  • Pros: Soft styles shrink as you drink, easily tucks away, and most have straps reducing the need for a continuous grip.
  • Cons: Might be annoying to hold, smaller holding less water, and can affect your arms pumping.
