The Criteria We Used While Searching For The Best Ultimate Direction Running Vests

Whether you’re hiking, biking, or running, we know how important it is to have a reliable  vest to keep you hydrated  and fueled during even the most intense trail-traipsing and mountain-scaling adventures. The following is a list of the metrics used for comparing each Ultimate Direction Vest.

Are they comfortable?

Training for an ultra-marathon is all about pushing yourself outside of your comfort zones. Yet, the last thing you should be worrying about is the comfort of your hydration vest. The straps and back should be soft and adjustable and not feel overly constricting or awkward, while still fitting snugly against your body to reduce movement to a minimum. They should also be breathable and lightweight enough so that you don’t have to carry too much additional weight, while not chaffing if you choose to go shirt-less.

Do they have room enough for adequate water-storage capacity?

The whole purpose of investing in an ultra hydration vest is to ensure you remain hydrated even on your longest runs. While bladders and reservoirs are typically sold separately from the vest, each vest needs to have the ability to hold enough water that will meet your particular needs.  Ultimate Direction vests hold a range of different size bladders, from from 1.5 ounces  in the more lightweight vest models intended for shorter distance running, to being able to hold 4 ounce reservoirs and bladders in the bigger vests that are perfect for longer hikes. In addition to reservoirs and bladders, some vests come equipped with water bottles, sizing up to 20 ounces each of additional water storage.

Is it easy to use?

It’s important to purchase a hydration vest that has pockets and storage compartments that are easy to access and use. Stuffing your gels into a pocket that you can’t reach with ease during your training is no good. The same goes for the accessibility of water bottles, water bottle storage compartments, and the straw if one is included – they need to be easy to reach, easy to use, and easy to clean.

Are they durable?

Whatever your sport is, if you opt outside you’re bound to face some kind of inclement whether at some point during your training. A hydration vest needs to be able to endure the hottest of days, the coldest of mornings, and the heaviest of rains and snow storms. A good hydration vest will keep its shape and comfort no matter the forecast. They also need to be able to stand up to sweat and moisture. The water bottle holders need to keep their elasticity, the water bladder shouldn’t easily break or rip, and the straps and clips should remain tight and secure even over time, so as to maintain a snug fit.

Other Important Factors to Consider When Choosing The Right Vest For You

Purchasing a high-quality hydration vest can be a serious investment, and we want you to be sure you make the best decision possible when shopping for a vest.


One of the first questions you may want to ask yourself is, what are all the ways in which I plan to use my vest? For some, the vest will be worn strictly on runs. Others might need theirs for biking, hiking, casual outings, or all of the above. If you plan to use yours for more than one sport or purpose, be sure you think about all the features you would need to fit your specific uses. For instance, if you plan to be hiking for days, you would definitely want to have enough storage pockets to store snacks and emergency essentials. But then if you also intend to wear yours for marathon training, you also need to consider a vest that has pockets that are not so big that they get in the way of a comfortable run. Are you going to need a place to store your car keys? do you need water-proof pockets for enduring possible rainstorms or treading through rising bodies of water? Whatever your needs, make sure your vest can cover them all.


Especially if you plan to use your vest for running, you may want to purchase one that isn’t bulky or too heavy. While a vest with two water bottle storage compartments that sit directly on your chest might be easy to access and convenient, they might block your natural running arm swing. Consider your particular running style. If you tend to exaggerate an arm-swing from left to right, a bulky vest is going to get in the way of your natural swing and be uncomfortable and annoying (although, it might end up helping your form in the long run!). The same goes for considering the bulk that is carried on your back: while the vest might have enough storage to carry all of your fuel and emergency essentials, the bulkiness might not suit your specific running style.


The type of material a hydration is made out of is certainly something to consider when thinking about comfort and use. While you probably want to stay away from vests that are not soft to the touch, you also want to avoid materials that are not waterproof and will not wick sweat and moisture. Obviously, the most important thing is to choose a material that is comfortable to you.

Pressurized or Not?

A pressurized hydration system will allow the user to squirt out water from the pack, as opposed to sucking it through the hydration tube. This might be useful on those especially-exhausting runs, climbs, hikes, or rides when your breathing is heavy and you just need to quickly and efficiently get water and/or electrolytes into your body. Consider how hard  you plan to work out before purchasing a vest, and if a pressurized hydration system makes sense for your needs.

How Cold Will it Be?

If you plan to use your hydration vests for winter sports or outside in sub-freezing temperatures then you will need a vest that has an insulated tube and bladder and water bottles to avoid freezing. You may find that you can additionally purchase a neoprene sleeve to cover the separate vest features, and provide some insulation (if they are not already insulated). However, in most hydration vests, the bladder is located on the inside of the vest, closer to your back, and so won’t as easily freeze since it’s so close to your body heat. Bottom line: if you plan on being in extremely cold conditions, take insulation into heavy consideration. Otherwise, it does not have to a top concern.

Can you clean it easily?

To avoid bacterial growth in bottles, bladders, tubes, and mouth valves, you will need to choose a vest that can be easily cleaned and disinfected. This is especially true if you plan to consume sugary liquids that might leave behind sticky residue. Ultimate Direction vests pride themselves on easy cleaning, for the most part, but at a cost. To clean the mouth valve and tubes, Ultimate Direction advises purchasing a special tube cleaning brush, and rinsing with soap and water. The bladder and reservoir are typically much easier to clean, in that they can just be turned inside-out and scrubbed by hand (or by filling with warm water and dropping in a dissolvable cleaning tablet.) As for the vest itself, consider how often you will be using it and, thus, how often you will be cleaning it. All of Ultimate Direction’s hydration vests are machine-washable, which will save on time and convenience. (However, Ultimate Direction advises to never machine-dry their products, but instead to hang dry).

Are they safe to consume liquids from?

If you’re going to be ingesting anything, you need to make sure it is safe. Ultimate Direction’s bottles and bladders are all made with BPA-free plastic and an FDA approved Polyethylene. In addition, Ultimate Direction uses a plastic urethane film in their bottles because it is safe, but its slightly porous texture may result in a slight yellowing effect. Users should not be alarmed by any yellowing – it is not dangerous and can be easily cleaned.



Q: How much does an Ultimate Direction vest cost?

On Amazon, Ultimate Direction hydration vests typically range from $80 to $160, depending on the size and storage capacity available, with most hovering around $120.

Q: Do Ultimate Direction vests come with a water reservoir and/or bladder?

No, most reservoirs and bladders for hydration vests need to be purchased separately.

Q: Do Ultimate Direction vests come with water bottles or flasks?

For the most part, yes. While reservoirs and bladders are sold separately, most vests include bottles.

Q: Other than a bladder and the included water bottles, what additional items can I fit in my hydration vest pockets?

Depending on which Ultimate Direction vest you purchase, there is enough room to hold two GPS Locators and/or smartphones, up to four gels, bars, and small snacks, and a small key in the larger models. Smaller models will generally have enough space for one or two gels and a smartphone or GPS locator.

Q: Can the hydration vests be washed?

Yes. All of Ultimate Direction’s hydration vests are machine-washable, but should never be machine-dried.

Q: Can trekking poles be attached to Ultimate Direction hydration vests?

In some of the models, yes. If you’re a hiker or climber and need to be able to attach trekking poles, look for models that are larger and with more storage capacity. Certain models come equipped with specific trekking pole attachments.

Q: What sizes do the Ultimate Direction hydration vests come in?

Most vests come in small, medium, and large.

Q: How do I know which size will fit me?

Most Ultimate Direction vests fit true to size, so purchasing a vest in the same size shirt you wear is a safe bet. Specifically, the following unisex guide may be helpful for pinpointing your size: size small for individuals with a 24 to 38 inch ribcage (61-97 cm), size medium for a 31-42 inch rib cage (79-107 cm), and size large for a 36-50 inch ribcage (91-127 cm). Ultimate Direction advises taking measurements wearing the style of clothing you intend to wear with the vest.
