A hydration pack or vest is very useful for speed hiking, long-distance running and similar activities. Hydration packs come with hydration bladders (often referred to as hydration reservoirs) and thus allow you to drink on the go without stopping. Although hydration packs and vests differ in cargo capacity, they typically don’t provide a lot of storage space and are thus best for activities where you don’t need to carry much besides water, snacks, an extra layer and other essentials. If you are not used to pack minimalist and often do lengthy activities such as day hiking, you might also want to check out our selection of hydration system compatible daypacks. These provide more cargo capacity but are also heavier and the hydration bladder has to be purchased separately.

Below is our selection of the best hydration packs and vests for speed hiking and long-distance running. We only included lightweight products that come with high-quality hydration bladders and provide good functionality and durability. To suit everyone’s wishes and needs, we included hydration packs of various sizes (i.e. cargo capacity and water capacity).

For shorter hiking trips a lumbar waist pack can also be a great alternative to a hydration pack; check out our selection of the Best Lumbar Waist Packs.

4. Buying a Hydration Vests for Hiking and Trail Running – What is important?

Harness:

The harness of a hydration pack or a vest has to be adjustable for good fit. Hydration packs typically have adjustable shoulder straps while vests feature adjustment systems that shorten the sides of the vest and thus bring the vest closer to your body. Both hydration packs and vests have at least one sternum strap which ensures that the shoulder straps are not jumping of your shoulders while you are active. Vests are often available in multiple sizes while packs are typically one-size-fits-all. The harness should also be made of mesh fabric for good breathability.

Weight:

A hydration pack for hiking or running should be lightweight because lightweight equipment puts less strain on your muscles and thus allows you to hike/run faster (read more about this here). In this selection of the best hydration packs, we only included lightweight products.

Hydration Bladder:

The hydration bladder that comes with the respective pack/vest should be easy to maintain and durable. Hydration bladders that are easy to maintain have wide openings which allow you to clean the interior of the bladder. Most hydration bladders also feature an antimicrobial film which prevents/minimizes the growth of microorganisms. The durability of a hydration bladder depends on the quality of the material and joints – such as the mouthpiece/tube joint, tube/water reservoir joint etc. In this selection we only included hydration packs which come with durable and easy-to-maintain hydration bladders. Furthermore, all hydration packs here come with hydration bladders with bite valves. Bite valves provide the most hassle-free access to water.

Storage any Hydration Capacity:

The hydration packs and vests in this selection have from 3.5 to 7 liters of storage capacity and from 1.5 to 2 liters of hydration capacity. All packs in this selection are big enough to fit a full hydration bladder, snacks, a lightweight rain jacket and essentials such as sun cream, phone etc.

Pockets:

Pockets allow you to organize your gear. Therefore, it is a great benefit if the hydration pack has multiple pockets. Some products listed below also have pockets for soft flasks which are very useful if you need to carry more water than what a hydration bladder can hold.

Attachment Points:

Some hydration packs have attachment points for trekking poles which is very useful for adventures where you might switch between running and walking uphill.
