Hydration backpacks worth considering for your next hike

Expertly reviewed by Judd Nesmith


It’s important to stay hydrated, especially when hiking, running or biking outdoors. This is especially true when it’s hot since intense sweating quickly depletes your body’s fluids. But it’s inconvenient to fish a water bottle out from the depths of your day pack whenever you want to quench your thirst. Hydration packs solve this issue by combining the day pack and water bottle. Some have room for tools and gear you might need on a long day hike, though more streamlined ones hold little more than their included water bladder.

Size and capacity

First, consider how you’ll use the hydration pack. If you enjoy long hikes in all seasons, you probably need something with plenty of storage space so you can pack everything you need. This might include a jacket, trail snacks and emergency first aid and survival equipment.

For some activities, though, a hydration pack is basically a flexible water bottle strapped to your back. When cycling, for example, a compact model minimizes drag while making it easy to take a drink. Even if it’s compact, the pack should still have enough space for small, critical items. This could include keys, identification and a flashlight.

In either case, you have options of varying sizes with exterior pockets. These are great for holding sunglasses, maps and other accessories for quick access. They’re also perfect for expanding your water supply beyond the water bladder’s capacity using lightweight water bottles.

Strap configuration

Hydration backpacks don’t have or need the same kind of support and suspension as full-size hiking backpacks. It’s still important to consider the shoulder strap, hip belt and adjustment strap layout. Thick strap padding and a chest strap are essential for hiking comfortably. Consider how far you can adjust the straps in either direction if you’re significantly bigger or smaller than average.

Even though hydration packs usually don’t weigh much, a wide hip belt with a little padding can make a full water bladder feel like it’s barely there. Also, keep an eye out for external fasteners or extra loops and straps for attaching miscellaneous gear to the outside of the backpack.

Durability and price

You can pay as little as $25 for a functional hydration backpack. Don’t expect it to withstand frequent heavy use without special care or significant upkeep, though. That’s not to say affordable outdoor gear isn’t worth getting. Some bargain-basement hydration packs hold up well over time. Hydration packs in and around the $100 range are more likely to be lightweight and comfortable with plenty of storage and durability.
