Criteria Used for Evaluation

Capacity

When trying to figure out the size of your hydration backpack, you’ll need to think about what you’ll most likely be doing while you are outdoors. If you know you need a hydration backpack for road cycling and you only plan to be outside for a couple of hours, then getting a more simple, lightweight pack would probably suit your needs and save you money.

However, if you are the type of outdoor enthusiast who likes to be outside for several hours, and you like to plan a lot of long-term activities, then you will probably want to consider a larger pack that will also provide you with extra storage options. Also, depending on the activity you partake in, like mountain biking or climbing mountains, then you’ll probably need more rock climbing gear carrying capacity in your hydration backpack anyway since you’ll need to carry more with you based on what you might encounter when you are outdoors.

If you’re doing anything for long periods of time in the mountains, you’ll need to carry a lot of water with you, but you’ll also need to hold extra food and extra clothing, and you might even need some type of emergency shelter. Hydration packs designed to hold several liters of water typically offer these other benefits, like the CamelBak M.U.L.E.

Ease of Use

Hydration Systems and Ease of Drinking
When you are selecting a hydration backpack, you’ll want to see how easy the hydration backpack is to use each time you need to take a drink, since some hydration packs work better than others in this category. Typically, higher-priced hydration packs perform very well each time you take a drink and usually provide you with hands-free options so you can get the water you need while you stay active. Also, if leakage is a concern, then look for a bite valve that features an on and off switch.

When you’re considering what hydration backpack to buy, you want to make sure the hydration backpack allows you to easily drink from it while you are actively moving. Also, you want to make sure you don’t wind up with anything that will leak onto you and create discomfort. So, look for hydration packs that have easy-to-drink from systems that are hands-free, and feature valves that can be turned on and off easily.

Filling
Another thing you’ll want to factor in is how easy the hydration backpack you are considering for purchase is to refill while you are outdoors and on-the-go. You want something that is both easy to drink from and easy to fill so that you won’t have frustrations when you are in the middle of your outdoor adventures and active.

So, how do you check your hydration bladder choices to figure out how easy each one is to fill? First, you need to see how easy the pack is to fill by trying to access the hydration bladder in the pack. Some hydration packs make their hydration bladders easier to access than others, usually by design.

To check and see where the hydration bladder is located in your hydration backpack, lift up the hydration pack’s cover, and look through the opening. Then, you’ll be able to see where the hydration bladder sits within the hydration back.

Some hydration packs still provide easy access because they feature hydration sleeves that keep the bladder in a zippered area of the pack. Hydration packs designed like this gives you full access to your hydration bladder without you having to totally take your pack apart.

Either one of these hydration backpack styles offers easy refill hydration systems, and you want to think about which style you prefer by analyzing where you are likely to be refilling your pack. Almost all hydration bladders are easy to refill from a kitchen sink, but if you need to refill from more shallow sinks or natural bodies of water, then you might want something that has a quick disconnect fitting. Hydration bladders that feature this make it easy to both access and refill them.

Comfort

How comfortable your hydration backpack feels when you wear it will depend on a wide variety of factors which include support, ventilation, and the straps on the system. We’ll cover each in a bit more detail below.

Support features
How much support you’ll need from your hydration backpack will depend on the amount of gear and items you typically bring along with you. If you tend to need a lot of gear when you are outside, then you’ll definitely want a hydration backpack that features extra support. Most manufacturers know this and design their hydration packs to fit this concept. Minimalist packs won’t give you a lot of pockets or carrying space for extra storage. So, if you plan on taking longer outings and know you can run into a variety of weather conditions, you need to consider purchasing a larger pack that will bring you both more support and comfort when you need it.

Larger packs are designed to carry more deals, and also feature better overall support systems to balance out this need. Most larger hydration packs give you more padding in your waist area, in your should strap, and also have a back pad. Also, some larger hydration packs are still made to be fairly lightweight and feature wireframes. Having extra support will give you more comfort when you know you’ll be going longer and need to carry more items with you.

Ventilation systems
Most high-quality hydration packs feature good ventilation systems, meant to help air out your back, shoulders, and waist as you move and sweat. It’s nice to keep both yourself dry and your back dry as you perspire and stay active, and most hydration packs offer a decent amount of breathability to assist with this issue. Remember, the hotter the temperature is when you are outside, or the more you sweat, the more ventilation you will need out of your hydration backpack.

To get a hydration backpack that offers a good ventilation system, consider hydration packs that have open mesh construction to enhance breathability and keep you cool. Most hydration packs have mesh-covered foam back pads that also have air channels to boost breathability. One pack on our list that offers a great ventilation system is the Osprey Syncro 10 because it has a mesh back pad and a lightweight wireframe.

Straps and belts
Depending on the amount of gear you’ll be carrying when you venture into the outdoors, you’ll need to factor in what you need for your straps and belts. The more gear you decide to bring along with you, the stronger your shoulder straps and waist belts need to be designed. Some packs give extra padding in the shoulder strap area and use wider design materials. Wider straps mean you have more strap contact with your shoulder, which decreases the number of pressure points you’ll feel in that area of your body.

Waist belts are typically designed with the same features of functionality in mind, and hydration packs that are made to be more stable will also be designed to spread the weight across your waist. Similar to shoulder straps, the thicker and wider the design, the better the support you’ll get from the waist belt area.

Read more

Capacity
The hydration bladder of the Seral can hold up to 1.5-liters. For a short ride, or for races with refill stations, this is great. However, if you’ll be out for hours with no chance to refill the bladder, odds are that 1.5-liters won’t cut it. And if it does, you’re not drinking enough water.

You’ll notice that the hydration bladder resembles a ziplock bag. It is thin and long and sits at your back. It is easily removed and put back into place and held securely in place with a divider sleeve and clip. The opening of the bladder is wide and allows you to small ice cubes if desired. Because the bladder is thin, the shape of the cube will be important.

Comfort
The AirScape back panel provides great comfort and breathability. There are compression straps on the sides of the bag and a pull-to-tighten waist strap for a great fit. The well-thought-out design of the bag keeps it from bouncing around on uneven terrain.
