Sizing Guide for Hydration Packs



Hydration packs combine two things that are imperative to outdoor activity, a backpack and a water source, voila! There are many activities and sports that you will find these packs very useful for. Hydration packs are fairly easy to size properly, that is, if you know what you will be using the hydration pack for.


The best way to size a hydration pack is by the activity you will be partaking in and for how long. Here we will go over basic suggestions of hydration pack sizing based on activity.


Day Hiking, Climbing and Backpacking: Here you will want to mesh a decent amount of water with lighter weight to carry so keeping the water reservoir to 2 to 3 liters you will have a good mixture of both size and amount of water.


Running, Marathon Running and Walking for Fitness: Here you want the absolute minimal design of a 1 liter reservoir to give you just enough water and not packing on much weight at all.


Road Cycling: Road cyclists may prefer to have a standard water bottle to shed any unneeded weight and keep themselves as streamline and aerodynamic as possible. If you choose to use a hydration pack while road cycling we would recommend the slimmest 1 liter to keep it light and streamline.


Recreational Cyclists: You will still want a streamlined hydration pack somewhere around 1 to 2 liters with some decent pockets to keep belongings while you ride.


Touring Cyclists: You will want a small to medium sized pack to fit all the essentials you need to bring with you and a reservoir between 2 to 3 liters to ensure you have an adequate amount of water.


Mountain Biking: Mountain bikers tend to use a larger bag with a 2 to 3 liter reservoir. Mountain biking is a very taxing activity making the thirst for water greater and with the extra pockets and room you can store spare parts, tools or anything else you may need.
