What to Look for in the Best Hydration Packs for Hiking
Now that you’ve got an idea of the best hydration packs on the market, here are a few things you may want to keep in mind to ensure you find the absolute best hydration pack for your needs:
What are you going to use your hydration pack for? If you’re going to be hiking, you’ll probably want an all-in-one pack that you can keep all your supplies in along with your water. You’ll also want something as lightweight as possible. If you’re camping, then you’ll only really need your hydration pack to hold your water, and maybe some snacks, since you’ll have a home base to hold all your other important necessities. If you’re a runner, a cyclist, or even a triathlete, you’ll need a light, aerodynamic hydration pack designed for comfort and speed.
The reservoir size directly corresponds to the amount of water you can bring with you. The volume of water you need will depend on what activity you’re planning on doing, how long you’ll be doing it for, what weather you’re expecting to be doing it in, and your own body’s specific needs.
Are you looking to carry anything else other than just water (like snacks, equipment, or clothes)? If so, you’ll need to find a hydration pack that has suitable additional cargo space. A tactical hydration pack is going to have a lot more storage and places for equipment. Check how many pockets or compartments it has and whether it can fit the things you need. The best hydration pack with storage will have the water kept separately to protect your goods.
Consider how much your hydration pack will weigh, both when it’s full and empty. If you’re running or hiking, the last thing you want is a hefty pack weighing you down. It will only make you tired and slow.
Straps and Belts
Some hydration packs have straps and belts that clip together across your waist or chest. These keep the pack in position while you’re traveling, making it easier and more comfortable to use. They also help more evenly distribute the weight of the water to avoid over-burdening your shoulders. The best hydration pack for trail running and hiking will have these attachments, so you’ll barely notice the pack while you’re running.
Is the temperature of your water important to you? If you’re going to be using your hydration pack in particularly hot or cold weather conditions, you might want to choose one with insulation.
