1. Hydration backpacks – These have a standard backpack design but come in a wide variety of sizes. They are popular for cycling, mountain biking, hiking, skiing and snowboarding. Backpacks are best for users who need to carry additional items such as extra layers, rain gear, nutrition or tools.
2. Hydration hip packs – This style of pack has become popular recently with mountain bikers, but it is a good option for hikers too. Hip packs keep the weight off your back which helps you stay cooler in the warm weather. Additionally, and for cyclists specifically, this style of pack distributes the weight to your lower body and around your hips, helping you maintain balance.
It’s important to remember that carrying water on your back may feel a little heavy at first. 1 liter of water adds approximately 2 lbs to your pack, so carefully consider how much you need.
1. 0.5 liters (16 fluid ounces) is a good amount for lower intensity activities like walking or hiking.
2. 1 – 1.5 liters (32 – 50 fluid ounces) works well for riders, runners or hikers who want to keep overall weight down so they can still move quickly.
3. 2 – 2.5 liters (70 – 85 fluid ounces) is the obvious choice for those who are planning longer adventures and want a pack large enough to carry other types of gear.
