running vest hydrationQuite naturally, the vest is intended to long races. Its capacity is just a bit smaller than of the other top-quality products. The bladder contains 1.5 L of water. 2 flasks can be placed to the front pockets. Is the capacity of each one only 250 ml? It seems to be not sufficient for ultra running. 500 ML bottles would fit good too.

Meanwhile, the total or carrying capacity of the vest is only 1.5L. It’s sufficient to carry only the minimal stuff, food, and clothes. Osprey Company was founded in 1974, in California (Santa Cruz city). It focuses on products for climbing and hiking.

  1. Lightweight;
  2. Long;
  3. Feature-rich.

Only 2 color options are available: black and red ones. I think alpine black is a bit similar to inov8 hydration vest by design. It’s a kind of minimalistic pack.

But for the handy pockets, the vest features also a sternum magnet, a whistle, the reflective logo. The straps are good both for left-handed and right-handed people.

  • the water pockets are small;
  • the mesh is not water-resistant.

Buyers’ Guide: How to Choose Best Hydration Vests for Ultra Running

What is the best source of electrolytes? You do know it already. Quite naturally, it’s water. Non-distilled solution. It is to be mineral-rich for the proper rehydration. It’s already clean if it’s the drinking water. So, just filter it not too thoroughly.

Drinking enough water is beneficial, as it:

  • maintains the balance of fluids in the body;
  • boosts physical performance;
  • prevents headaches;
  • increases your energy level;
  • improves brain function.

Water is essential during marathon and ultra marathon races. It makes running more efficient and more comfortable. However, how to run with it? We would like to avoid splashes and stops.

Best Way to Run with Water

Do you need to carry your drinking water and run with it? Use a hydration bladder. These reservoirs are made of soft plastic. They are squishy and flexible. The bladders are equipped with long tubes. They make it easy to access water.

There are also soft flasks, equipped with tubes. They are commonly placed to top, front pockets. They are simple to use and durable. The bottles are versatile. They can be used to carry various liquids. However, running vest bottles vs bladder are smaller. They are longer to refill (due to the smaller mouths). Additionally, the risk of leaks and mechanical failures is higher. Have you selected the bladder? You can use both options. However, where to place the water reservoir for the best use and stability?

Hydration Vest vs Backpack

Quite naturally, a pack is good for hiking, camping, and biking. Its capacity is huge. So, if you are not in a hurry, it’s easy to use. However, running a marathon with a hydration pack would be a bit heavy.

The vests are more lightweight. They guaranty perfect stability and fit. Multiple small pockets are sufficient for essentials and the necessary stuff.

If your race is not long-distance, you can use even a belt. These devices are small and lightweight. No chaffing or bouncing is possible. 2 small water bottles can be attached to the belt. So, the water capacity is about 0.5-0.6L. It can be sufficient up to 10 miles run. Even a zippered pocket is commonly available. You can place your keys or phone there.

However, hydration belt vs vest is too small for a marathon race. There is no space for your clothes or special stuff. The weight is spread across your hips. The shoulders and backs experience no pressure. Your movements are not hindered.

Basic Hydration Options for Runners

Looking for a suitable hydration vest, estimate the distance to pass and the necessary storage and water capacity. Additionally, consider the items:

  • durability;
  • breathability;
  • comfort;
  • useful features.

The vest is to be lightweight, soft and adjustable. Numerous, easy to access pockets would be helpful. The color and attractive design matter only at the race start and at the finish. Selecting the right size is more important. It makes you feel comfortable during a long run.

Selecting a suitable vest, don’t forget to check the bladder’s availability. It can be included or not. Therefore, if you buy it additionally, it affects the total cost.

Final Verdict

The best hydration vest for ultra running is Circuit by CamelBak. It’s bright, functional and lightweight. The item by Nathan is compact and body-mapped. The vest by Solomon features a unique, Kangaroo pocket.
