Criteria Used for Evaluation

Comfort

Ultra-marathon running is about pushing yourself hard and outside of your comfort zone.

Therefore, getting the most comfort out of your hydration vest is a big deal. They should have soft straps that are easily adjustable without any awkward constrictions while still fitting snug, reducing any unnecessary movement.

The best hydration vests should also breathe well and be extra light. Ultimate Direction vests are designed with attention to all these comfort details. Moreover, they know not every runner is made the same and that is why they have so many options, using runners like you to help work in comfort, catering to different needs.

Durability

Hydration vests are made to carry extra weight without adding any. They need to be able to take a little pressure and bounce while still protecting you against chaffing and the elements.

The best hydration vests will keep shape and elasticity through some of the harshest runs. They shouldn't rip under the pressure of a few water bottles and energy gels.

Ultimate Direction has many designs to choose from with high durability standards. Each one is made to cater to a certain running style and distance and is, more than not, made with rip-stop materials. Also, keeping the vest just snug enough to prevent sliding around without restricting the runner’s movement helps with durability as well.

The less a vest moves, the less likely it is to have added strain. A durable design is going to maintain the structure and hold weight, it is that simple. You don’t need a fancy vest, you need a functional and durable one.

Versatility

For some, hydration vests will be worn strictly on runs while others might use it to bike, hike, or for other types of outdoor adventuring. Therefore, versatility plays a huge part in what makes the best hydration vests.

Having enough storage without weighing your down is a great place to start. What can you use the vest for? Are the pockets and holders good for other items? What do I need to have versus what the vest offers?

These are all good questions to ask when using your Ultimate Direction vest for other activities other than running. It is also great to know what the weather is like and how the materials are going to paly into the elements. How long you will be trecking versus how much space and water storage you have will also play into the most versatile options.

Materials

Material will play into durability and comfort when searching for the best Ultimate Direction Vests. Softness, moisture retention, and seams are just some things to look at when thinking material.

The wrong material can leave you chaffed, irritated and uncomfortable. It is also where you start with durability. Most well-made hydration vests are made to not rub, tear or breakdown in sweat or wet environments. This is why we really look hard at materials, we want your best option to last you as well.

Use

Since Ultimate Direction makes 22 different hydration vests, there are a lot of options and each one has something different to offer.

We found that the smaller options are best for simple distance running or training. Others larger ones accommodate more Ultra style runners, hikers, and even light outdoor travel.

It’s important to purchase a hydration vest that has pockets and storage compartments that are easy to access and use as well. IT makes no sense to pack in water and energy where you can’t reach it. Items need to be easy to access when you’re on the go and stopping isn't an option.
