Buying Guide
So, you have learned about the best packs currently available on the market. Now let’s look at the elements which actually make these the best hydration pack for running. You need to consider these factors before buying the pack if you want to make a smart purchase.
Capacity
Capacity is the most essential factor to consider while buying a hydration pack. As it depends on the amount and the way you can carry your load while running. Typically packs have two ways to carry water: in water bottles in the front of the vest or in a hydration bladder that is inside a pocket in the back. Which style you choose depends on your personal preference.
To help you decide which is best for you, you need to consider fluid and gear capacity both.
Fluid capacity
Generally, it refers to the amount of water or hydration beverage a pack can carry. The hydration capacity means the total amount of liquid a pack can hold including its carrying containers. It usually ranges from 20 ounces to 2 liters and is carried in bottles, flasks, or reservoirs.
How much water you need to carry depends on your intended use of the pack. If you are planning on a shorter run around the neighborhood, then a smaller size is enough as you’ll have access to water and refill. However, if you need one for trail running on the wilderness or practicing for marathon running, then opt for the larger fluid capacity.
Make sure the design of the hydration pack is well built and leak proof. Moreover, if the pack is also designed to keep water cool, then it’s an added perk. If you can’t make up your mind, go with the larger size. It’s always better to have extra water handy. When you don’t need the extra water, just don’t fill it all the way.
Gear capacity
Most packs offer plenty of space to keep commonly used items. It could be anything from food, electric gadgets, toiletries, accessories, an extra set of clothes, etc. It actually depends on you, the gear you prefer to bring on a run. The more you need to carry with you, the more space you’ll need in your hydration pack.
Normally capacity is described on the pack in liters. For one to two hours run, you’ll need about two liters of space. For runs lasting three to six hours, you’ll need a capacity between four to twelve liters. 5 liters is the average medium-sized pack. If the run lasts six hours or longer, then you’ll have to look for the largest capacity available there.
Just like with water capacity, determine the gear capacity according to your requirements. Sometimes, small capacity doesn’t mean worse quality. If the pack is efficiently and well designed and fulfills your needs, then it’ll be a way better option than larger packs. So, look for the one that specifically meets your choice and preference.
Pockets
The best solution is to have a pack with different pockets for multiple uses, at least one zippered smart space for storing small and valuable items, and an easy to reach and access design.
However, for a running pack, if you get a heavy pack with multiple pockets with accessories, it’ll be more of a burden. Too much weight on your pack will definitely slow you down. Better to leave unnecessary supplies at home and just bring the basics.
Additional pockets come in handy as the deciding factor when you are confused between two models. It is not an absolute requirement, but more of an added bonus of a great hydration pack.
Comfort
One of the key factors to consider is to check for comfort.
Running with a hydration pack for hours is already exhausting enough. And if your pack causes chafing, rubbing, or discomfort on top of that, it’ll become a run from hell. It won’t be a surprise if you take a break from running after that. Bad experience with an uncomfortable pack can make you drop running altogether.
So, look for a pack that is comfortable to wear and fits properly. The pack should be tight enough to avoid awkward bouncing but not so much that you can’t breathe well. Look for stretchy, elastic, breathable, and fully-adjustable straps and materials. That way you can be sure of breathability along with even weight distribution on your body.
Also, packs hold heat closer to the body and cause overheating or extra sweating. In that case, you need a pack with good airflow circulation. So, consider a well-constructed pack with see-through mesh material for the shoulder straps and padded back panel.
Sizing & Fit
Along with comfort, the fit is also another important factor to consider. Fit is personal for everyone and will vary according to different preferences. The ideal fit will snugly hug your body without hindering arm movement or breathability.
Usually different sizes like small, medium, large, etc. are available with most hydration packs. You can also find models with one-size fit all. These different styles come with adjustable straps for the best fit. The one-size fit all packs tend to have more strap and adjustments to suit a wide range of body types.
You need to consider the pack which is not too big or not too small for your body. A bigger pack may bounce and sit ill-fitted while running, whereas a smaller pack may restrict your breathing and cause rubbing and chafing.
So, how to decide which size should you get? For that, it’s best to try on the hydration pack yourself. That way you’ll be able to determine how well the pack adjusts or contours to your body. In case you are unable to do that and actually shopping online, measure your body and follow the manufacturer’s sizing guidelines to get the right fit. It’s better to compare different choices before finally deciding on a model.
Our advice? Try on different models and feel the fit. Your body will let you know which one you should get.
Women’s Fit
Women’s fit usually refers to the hydration packs specially designed for women’s bodies. It’s certainly true that there are fewer women-specific models out there. However, you can still find many, with tons of variety in size and shape.
The women’s fit is mostly different from men’s models in the shoulder and chest straps. These are designed for a more petite build. Women’s hydration packs for running have more room in the bust and narrower shoulders while also being cut shorter overall.
Still, everyone has different body types and different comfort zones. So, it’s better to choose one accommodating your body.
Weight
When running with a hydration pack, you need to consider the factor of weight. As you will be carrying additional water, your pack needs to have a lightweight design. Along with comfort, you should be able to run freely for hours, without the weight of the pack slowing you down.
Moreover, the lighter the pack, the less strain you’ll be putting on your body.
The trick is to choose a lightweight hydration pack without sacrificing durability or functionality. People tend to have a misconception that lightweight = less durability. That used to be true to some extent. However, many companies nowadays make lightweight models without compromising quality.
Additional Features
Nowadays modern hydration packs offer more advanced and different models that come with smart features. However, all these extra features have the same goal – to provide more storage, ensure safety and comfort.
Packs made with reflective and high-visibility materials or having a reflective trim are easier to spot from far or on the night. Adjustable and compression straps will help you secure your pack. Built-in safety whistle will reduce security risk, whereas water-resistant material will make the pack durable and waterproof.
Different users want diverse features specialized to their needs. So decide what is more important for you to have in your hydration pack. Try to look for what are the additional features the pack is offering and whether it’ll be useful to you.
Final Verdict
So, are you ready to get your own hydration pack now? Rest assured you will not regret buying it. These packs can provide you the mobility and comfort while running as no other generic backpacks can. After reading on surely you have got a clear idea about what you need and prefer in a hydration pack. Even if you are still undecided, don’t worry.
